Milk - Good or Bad?

So chocolate milk has been a major part of my recovery diet for a long time. In fact, I was probably one of the leading milk drinkers in Canada. And the benefits of milk are scientifically proven - "according to one study". The Got Chocolate Milk folks say so. I found one too (1). That's definitely science - a little tiny bit. Most claims for milk show that it is equally as good as sport drinks as a recovery drink (1, 2, 3). So it seems clear, milk is a good sports drink. And it is real food, so you feel better about drinking milk than drinking a Coke for example.

But many of the papers note that milk isn't suitable for everyone. Here is my experience as an "everyday athlete". I have been having sore knees after hard rides for quite a while now. Yeah, I'm getting old and that seemed like a reasonable explanation, as sad as that might be. But on a whim, I thought I would search the web for foods that could lead to joint inflammation. Milk came up regularly as did other foods. But since I was such a milk pig (cow?), I decided to try eliminating it from my diet for a bit and see what happened.

Holy milk intolerance Batman! I felt noticeably better in a day and even better the day after. My knees felt numb - or maybe that's just what normal knees feel like? Practically instantaneous results and the dramatic improvement was totally unexpected. I have since been putting in hard consecutive rides and the knees still feel great. I also find I am sleeping better through the night, for whatever physiological reason. I don't think this is a placebo effect as I actually had no real belief that this would work. Of course if it continues - who cares? I generally consider food-phobes crackpots. Now I'm a crackpot too.

It would be easy for you to try this same experiment, particularly if you are feeling your joints are sore.

We are all different and have different allergies and intolorances to food and other things in our environment. Bottom line, don't believe something is good or bad because somebody tells you it is (assuming it is real food and not processed crap - processed crap is still crap). You need to find out what works and doesn't work for you. I've dropped milk from my diet completely. It was easy - I switched to almond milk and don't miss cow milk a bit. I still plan to experiment with cheese as cheese would be hard to give up.

I did briefly consider soy milk, but the word is it sucks. And it contains female hormone-like substances which I am quite certain I don't need. And may increase the risk of dementia which I can guarantee nobody needs. Soy scares me.

The almond milk was tasty off the get-go. And the health risks seem relatively few and minor compared to soy milk. I like the Silk unsweetened for my chocolate milk as it is creamy and has a distinct almond flavor - chocolate almonds anyone? And only 30 calories per glass versus the 100 in skim milk. I like the Earth's Own unsweetened version better for cereal - not as creamy, less almond flavour - doesn't overpower the cereal. 35 calories per glass. Both brands match milk for calcium, vitamin D, etc. exactly - as they are fortified. The other thing - I'm going to avoid going overboard with almond milk the way I think I may have with cow milk. Keep it to only a few glasses a day and make sure I drink other stuff like tea, water, and those nasty sports carbohydrate drinks.

Actually, I do miss ice cream and milkshakes too. Especially the chocolate variety.

Schwalbe Marathon Winter Studded Tire Review

Marathons after yesterday's snowstorm
I hate to say it, but it's (winter) stud time again. I have had the Schwalbes mounted for a few weeks now and they have been necessary. These are the best winter commuter studded tires I have found so far. Sure they're heavy (920 g each for mine, listed at 910 g) and they roll slower than normal cyclocross tires, but they are lighter and faster than other studded tires I have tried. The tread is reasonably aggressive, but not overly deep. Squirms and slips a bit on deep snow, but most tires do. These aren't ice spikers after all.

I rode these tires for most of last winter as well. When I got the tires I noticed there were a number of studs that were not properly embedded. So I embedded them properly. From Schwalbe:


In order to ensure that spikes are permanently fixed, tires should be run in for about 25 miles (40km) on asphalt, while avoiding any fast acceleration or heavy braking.
 
I first rode them for 50 km on pavement without any fast acceleration or heavy braking and lost 3 studs anyways. They were all in the same area of the tire so probably a single bike handling episode ripped them out before they were embedded properly. I replaced them with new studs. Since then I haven't babied them and have only lost a single stud in quite a few km of ice and pavement riding - 2000+ km? Who knows, but I do commute year round and use these for 3 or 4 months each winter whenever its icy. In this neck of the woods, we get a snowstorm followed by warmer weather and lots of salt applied by the city. That turns the bike paths and roads to a mix of ice and bare pavement, mostly. Hard on studded tires, but these tires have the carbide studs so stud wear hasn't been an issue (unlike steel studs). The rubber itself shows no sign of any wear.

The tires make the bike ride very rough on rough pavement when they are pumped to 80 psi, but at lower psi they are smoother, if slower. Not an issue if there is a bit of snow on the ground. I tend to pump them to the high end of the range so they roll faster and assume the rough ride increases my bone density. Win, win. If it is extremely icy I will reduce tire pressure for more grip though. You can still slip around, even with studs. But for the most part I can ride as hard as I want without crashing and pass lots of tentative people on the bike path on slippery days. I haven't crashed once with these tires, fingers crossed.

I like the reflective sidewall for the dark days of winter, but to be honest, it gets all dirty and not so reflective after a while. Could wash them off I suppose. I don't fuss it.

I wish they made a narrower version for my particular application. And in a folding version for lighter weight. I have the 700x35 which is their narrowest version for 700c wheels. Somewhat overkill for me. Can't imagine using the 700x42. Those would be real beasts. This tire is also made for several other wheel sizes including 26 inch.

The tires have a belt of something or other for flat protection. Good idea as fixing tires in winter sucks. No flats for me to date. The tire is very solid and thick so it would take quite a nasty piece of road garbage to cause a flat. Pinch flats are pretty much impossible with minimum recommended tire pressure or more. The tires should last for a very very long time given their heavy construction.

All in all, these tires make the best of a bad situation for commuting on icy roads. I do take every opportunity to swap them out for my Schwalbe CX Pro tires though, conditions permitting. I like the speed and stopping the clackety-clack of the studs on the pavement. Am I purposely picking only Schwalbe tires? Not really, it just worked out that way.

January 18, 2014 Update: Lots of miles (80 km yesterday), no visible wear, studs are staying put. Never had a flat. Very good tires.

Lance on How to Prevent Doping


Talk about irony. It is 2007 and an expert speaks.... I'm amazed Lance can sing from the songsheet so well. It's not enough just to dope, you have to believe.

Genetic doping, the next big thing. Wonder if that is happening yet? Apparently it is.

Sky - Can They Be Trusted?

Let's look at the question - is Sky clean now? Well let's review a bit of Sky history.

Wiggins jumps contract to move from Garmin to Sky
Once Wiggins came 4th in the 2009 TdeF, Sky became interested in him as they needed a GC rider and Wiggins was British to boot. There was no need to let a little thing like a contract get in the way and Garmin didn't have the legal resources to fight Sky, who had the legal hammer in terms of resources. So Sky got their way and in the process demonstrated questionable ethics. Garmin took the settlement as they really had no choice.

British Pro Cycling and Sky - Equipment
Sky is the principle partner for British Pro Cycling. Their websites are intertwined. Now there is a UCI rule designed to keep a level playing field for the sport. It came about after the 1984 Olympics where the Americans spent big bucks on high-tech bikes and people won medals who were not perceived to have been the best athletes. The UCI rule requires racers use equipment "of a type that is sold for use by anyone practicing cycling as a sport." Neat concept. If you are a manufacturer, you certainly aren't going to make money producing equipment that is so specialized and expensive that no one will buy it. So despite the shocking sticker prices you see, bikes are relatively cheap and are not Ferraris. No one wants a Ferrari in cycling after all.....

And then along came Sky. Their deep pockets mean that British cycling can flaunt the spirit of the rule. By creating specialized high tech equipment that they could care less if they sell, ever, as they don't need the money, they can provide a little extra edge for the Brits. An edge that no one else can match at this time. The equipment is for sale if you have ridiculously large amounts of money and can wait for an indefinite period for delivery. See what they have for sale on their online catalog. No prices but if you have to ask, you can't afford it. For starters a helmet is $4700. This strategy only works for the Olympics (and track cycling) where branding rules limit the ability of sponsors to get their brands on the equipment anyway. In your usual UCI race, sponsorship branding is only limited by bad taste and the equipment sponsors ensure the rules are met.

Is it cheating? Perhaps the lawyers would tell you they meet the letter of the law which makes them innocent of course, doesn't it? The spirit of the rules are irrelevant. But is this behavior ethical?

Thanks for the Omerta Dave
Omerta
In pro-cycling the Omerta is the shunning of anyone who speaks honestly of doping. They can't get jobs, they can't win races, they have no friends. The riders, sponsors, journalists, team managers, etc. enforced this rule. As a result, it was impossible to clean up cycling and still may be impossible, thanks to organizations like Sky and Omega Pharma. Sky's "holier than thou" anti-doping policy which prohibits anyone ever involved in doping from being on the team in any capacity sounds a lot like Omerta doesn't it? Forcing their employees to sign a pledge claiming that they had no involvement in doping or they lose their job certainly won't help cycling identify the facilitators of doping. The riders were mostly victims (not Lance though) and it is the facilitators and promoters of doping that have to be weeded out. This approach enforces Omerta and keeps everything hidden and out of site.

Does it help clean up the sport? I don't think so. Does it push people to be dishonest and protect the facilitators? Definitely. Does it allow Sky to pretend they are better than everyone else and therefore more deserving of your support?  I think that may be it....

Tour de France Performance
In 2012, we saw Sky take a page from US Postal's How to Win the TdeF Manual. Ride at the front so fast that no one can pass you. Easy to do when you have a world class doping program - which takes up most of the rest of the Manual apparently. How exactly did Sky get their domestiques to that same level? I have no idea.

Is There a Doctor in the House?
What's Up Doc?
Geert Leinders was a questionable choice, even before the USADA report came out. Sky hired a doctor who others warned was associated with doping. And defended that choice through the TdeF and until USADA made everything crystal clear to everyone. Without USADA, he would presumably still work for Sky. Now just what was Geert doing with the riders at Sky and why was Sky defending him knowing of his employment for teams that had a doping history. I thought they had a zero-tolerance policy? Zero-tolerance or zero-tolerance to anyone who gets caught? I'm sure the lawyers have this one under control too.

Wiggins doping denial has an eerie similarity to Lance denials don't you think? Just a little more colorful, that's all.

Payback Time For Wiggins?
Apparently, even the nouveaux riche don't like to pay taxes. Even when they got where they are through state-funded sports programs. Wiggins is engaging in a tax dodge that is legal, but certainly not honest. Check it out here. I guess that flag is just a scarf, he must have been chilly.

In Summary?
If you are rich and big enough, you can manipulate the rules and get away with it. It's good to be big. Sky has a history of doing what it takes to win/get their way without being too troubled by ethics. They don't act like the good guys (they're not Garmin Sharp). I don't have to trust them, do you?

Oh yeah - I think doping is alive and well in today's pro cycling. Perhaps not as blatant a boost, but a boost none the less. But only if you can afford a truly sophisticated doping program - like US Postal but with 10 years of improvements. Genetic doping is likely here. Anyone need a little repoxygen? And it appears there are undetectable versions of EPO on the market.

Theoretically, the ultimate program would be one where even the riders didn't know - they just take their special gels, pre-race and recovery drinks. Then you tell them all the little things add up to big performance improvements and watch them go. Of course, many will do it without having to be fooled. But they lie better if they don't know they are doping (except Lance).

Avid Shorty Ultimate Cyclocross Brake Review

So last Xmas, Cyclocrossworld had their big sale and I was able to buy both front and back brakes for almost half price. Everybody raves about these brakes, price was right, and I wanted something that was easier to swap wheels with than the mini-V type brakes. Thanks Santa. I've been using the brakes quite a bit lately as I smell cross in the air.

The good news - yes the brakes work very nicely. I only use the power setting and I can negotiate just about anything out there, even ridiculously steep mountain bike downhills where my butt is well behind the saddle. I ain't afraid of nothin (if they aren't too rocky).

The brakes seem to have found that magic balance between power and rim clearance. They have a goodly amount of both. Brakes like the mini-V versions have even more power, but little rim clearance. Difficult to swap wheels in a hurry. Brakes like the TRP Eurox cantilevers have lots of rim clearance (easy to swap wheels fast), but no power.

And they are light - mine weighed 130 g versus 160 g for the TRP 9.

All good right? Well there is a fly in the ointment. For some reason, the engineers at Avid decided to make the brakes use just about every tool in my toolbox for one thing or another. Really, 4 different hex wrenches and even a torx are required for set up. Plus a 15 mm wrench for pad clearance adjustment - feel like carrying one of those with you on your rides? Fortunately, my clearance has stayed put OK. Particularly irritating as I realized just last night, swapping out brake pads requires a ridiculously small 1.5 mm hex wrench which I couldn't find and had to buy. I guess the more typical brake pad holder hex sizes weren't good enough - far too large and ungainly.

Really? Get with it Avid. You have a good working design, but your insistance on cobbling together a multitude of nut and bolt sizes takes the shine off it. The brake pad holder micro hex is a poor design in my opinion. Some people have to switch between carbon and aluminum brake pads and I envison that teeny tiny hex is going to be quite easy to strip if you have a bit of dirt in there or you haven't cracked the hex bolt open for a while. Fortunately, you can buy brake shoes made by someone else that don't have this flaw. Some are even cyclocross specific!

So the Avids work well, but still room for improvement. They aren't the "ultimate" despite their name.. You'd think getting parts from the odds and ends bin would make these relatively cheap, but they are rather pricey. Maybe Tektro can come up with a cheaper version - you really just need to get the right arm length - and use SRAM-type brake pad holders. You could probably charge $25 and make a killing.

Of course disk brakes will take over soon. Except who wants to toss a perfectly good bike just to get better brakes? I'll have to wear my Ridley out first and I expect that will take some time. Like forever.

January 20, 2014 Update: Still using the Avids and they haven't given me any issues whatsoever. No tuning, no adjusting, they just work. Which is good, eh?

Halo Headband Review

Well now the sweaty season is well and truly upon us, I thought I would mention the Halo headband. I have noticed that with advancing years and retreating hairline that sweat now gets in my eyes quite a bit more easily than it used to. I think hair is a built in headband, mopping up excess sweat and providing a larger surface area for evaporation. That's my theory anyways.

Nowadays, I do know sweat in the eyes can be a problem, particularly with certain helmets. Stings, doesn't it? So here is an invention that I have used for about 5 years now that works. Despite the cheesy, cheap illustration the product is well made. The lateral transfer of sweat is a bit of a stretch I think. And I have never personally experienced sweat dripping down the side of my head or behind my ear. I think the rubber just stops it from running down your forehead and the sweatband provides a good evaporative surface.

Importantly, regardless of the mechanism, it works much better than no headband. This one is nice and thin so it doesn't unnecessarily add to the heating problem and readily fits under a helmet. Works great on the trainer too. It easily rinses out under the tap when it gets kind of salty and smelly. Good product that does what it is intended to do.

Wiggins Olympic TT - Maybe It's Not The Bike?

What the heck? This bike isn't high tech. The brakes aren't integrated and hidden, there is no nose cone, the forks look like they are from a road bike, no electronic shifting, and the seat tube isn't even protecting the rear wheel. What's that bike worth - 500$? How could he possibly win on that? Unless... it's not the bike that wins races? You mean if I rush out and buy the latest, I can still be beaten? This is really bad news.

Glad he wore the booties - I have booties too. Maybe it's the booties?

CycleOps Powercal versus Quarq Review - Is Powercal Any Good?

Short answer - YES, it's surprisingly decent. Long answer - see below

Well if you're like me you have been wondering how you can measure power in a cheap way, but you don't want a piece of crap. And you want something that can take a hike, a run, (probably not a swim), hockey, etc., etc., and convert it to a cycling equivalent that I can put in my WKO+ to find out how tired I am and how fit I am getting. Theoretically, this thing does all that - if it works. Multisport power measurement nirvana.

Reading the reviews on line I have found them to be lacking significant details - like plotted comparisons. And all the armchair experts whining about how heart rate and power aren't fully coupled and therefore it can't possibly work made me think that there had to be more to this thing than a simple heart rate to power correlation. Any high schooler could do that and everyone who has used a powermeter would know it wouldn't work very well. Obviously, change in heart rate had to be part of the calculation, but nobody seemed to mention it. Where are the data?

Anyways, I felt the potential benefits outweighed the potential for a piece of crap and I bought one for a very reasonable price. Really, price is the other huge advantage for this thing compared to other power meters (can you say "an order of magnitude"?) - if it works of course. Seemed to be vaporware for a long, long time, but finally I was able to buy one - arrived yesterday.

So I took my Quarq - recently calibrated and rebuilt to boot - hitched to the Garmin 500 and my brand new Powercal hitched to my Garmin 705 on a 3+ hour training ride today. Talk about data - two displays to watch while listening to tunes on my Blackberry. I was wired to the gills. Radiation nirvana.

The value of a long ride is that I could put the thing through a variety of activities - short sharp efforts between stop signs and lights, small hill attacks, longer hill attacks, some steady riding and some slacking off of course. About the only thing I didn't bother with was high intensity sprints because I doubted it would work for those anyway.

Now for the stats:

Surprise! The Powercal isn't simply using heart rate as predicted by power. Actually not a surprise as that would be pretty useless. When riding, it is obvious that the meter is using the rate of change of heart rate as well. When your heart rate is increasing, power is high for a given heart rate, when your heart rate is dropping, power drops, even to 0 at high heart rates. Which is entirely realistic if you stop pedaling. Looking at the data, the algorithm is complicated - e.g., for a rising heart rate followed by a steady heart rate - power rises and then drops - for both the Quarq and the Powercal. That's comforting.

Looking at the scatter, it is similar to the Quarq, but notice the banding of the Powercal relationship. I could speculate that it is using discrete categories of rate of change of heart rate instead of a continuous relationship. But I prefer not to speculate. The important part is that this scatter looks realistic. Since points are obviously plotting over top of each other due to the discrete nature of the relationship, we can't tell if it matches the Quarq really well or not. Who cares. The next graph is what you should care about.

Well I'll be a monkey's uncle. That's not too bad is it? This is without calibrating anything. Apparently, calibration didn't tend to make anything better for most of us, so CycleOps removed all the videos on how to calibrate that used to be out there. That's a timesaver. And you don't need another powermeter to use this thing. This graph shows that the Powercal does a decent job of tracking all kinds of efforts.

I wanted to zoom in on the first part of the ride where my power was more erratic due to lights, pedestrians, stop signs, etc. Here's what I saw:

Again, amazing. There seems to be a noticeable delay in peak efforts which is understandable as there is a time lag for heart rate to respond. But only a few seconds and the peaks are mostly all there.  Anything over about 20 seconds is nicely tracked so you can use this for most types of intervals. Nice and not unlike comparisons of powermeters that measure power directly I have seen.

Unfortunately, for me it does tend to underestimate power at higher power levels and slightly overestimate power at very low levels. I expect results will vary depending on your unique heart rate versus power relationship. I think the relationship is a bit better than the trend line shows - the very low values are pushing the line down a bit at higher wattages. The scatter is expected due to the time lag relative to the Quarq inherent in heart rate.

How important is this? Well for comparing to other cyclists, this suggests I'm not working as hard as I really am. Might matter for bragging rights for example - (My power was X for 5 minutes, what was yours? Yeah but who got up the hill faster? Just export your files as GPX for upload to Strava and no one will ever know.). For planning and evaluating workouts, this lower power doesn't matter at all. Relative to itself, it is consistent and therefore doing a pretty good job. There are occasional random spikes, but not a big deal.

There you have it. I can self calibrate - on this ride the Quarq TSS was about one third higher than the Powercal (actually 38%, average power was 13.5% higher, normalized power was 17.6% higher, VI=1.25).  Maybe do a couple of more rides to check. I'm not too worried that the power values themselves don't match but I want a good measure of training stress. If you didn't have another powermeter, you wouldn't have to care about calibrating one to the other. You don't need to match anything.

Other comments - I really like the heart rate strap on this thing - very comfy but it may be a bit short for big guys. Works fine for me though and I'm over 180 cm (5 11 - used to be 6 feet, but I shrunk). I did have to loosen it almost all the way to fit my gigantic chest.  Maybe it stretches, I don't know. No trouble syncing to my Garmin. Heart rate average was 1 bpm lower than the Garmin strap. Go figure. Makes it that much harder to hit threshold I guess.

Multisport nirvana? - check. Low cost? - check. Good buy? - checkmate. Unless you are a bit anal, this thing is all you really need for training with power. Buy one, determine your threshold power using it as described in many training books and blogs, and then train, dammit. You just saved yourself a couple of grand or so and guess what? You will get faster just as quickly with this as you would with the expensive powermeters.

Additional Calibration Rides
Did various rides and portioning of rides to get Variability Indices of 1.01 to 1.43 for 30 to 200 minute chunks. And lots of variability of effort from cruising to time trial mode, to intervals. No apparent relationship to variability index. Stopping does tend to give you a power reading on the Powercal when you move around so that of course is wrong - it reduces the difference between the Quarq and the Powercal. Normally not significant (e.g., traffic lights) unless you do it for a good chunk of your ride - pause that Ant+ device when you stop for lunch. Other than that I am getting an average of 31% higher TSS, 11% higher Ave Power, 14% higher Normalized Power for the Quarq on this hodgepodge of data.

August 24, 2012 Update - Well I have had some quality time with the Powercal and I still like the way it works... most of the time. I have encountered one problem that also occurs with my Garmin heart rate straps, but not as badly. They only work well when you are sweating at least a bit. When you are a bit chilly, like today unfortunately, it takes some time for the monitor to give you a reasonable reading. On the bright side, I have never hit over 3000 watts until recently. But I'm a little concerned that might be incorrect. I am finding the Powercal heart rate strap is a little more temperamental in this regard than the Garmin strap. Once you are fully warmed up and sweating a bit, it works well. That can take 15 or more minutes though depending how cold and windy it is. And yes, I put spit on it.

October 14, 2012 - more update and some comment cleanup - I am finding the meter works well when I'm sweaty and works really poorly when I'm a little chilly as happens all too often for the foreseeable future - until spring. I don't have to be hypothermic chilly, just that "warm enough to keep riding and not put on my jacket" chilly. Basically, the heart rate readings get sporadic and the power readings get really wacky. I did try an assortment of cremes and some helped a bit. But none solved the problem. The heart rate monitor definitely does not pick up your heart rate as well as the Garmin strap and it seems to be getting more sporadic over time for some reason. Here is a very good thorough discussion of the issue and solutions. This can be quite irritating if you are a detail person. Plus your TSS can be somewhat out of whack compared to the TSS when you manually remove the spikes.

The strap doesn't receive data from the Garmin, it only sends. I made my weight 270 kg and my power readings were unchanged. I'm pretty sure I was the fastest climbing 270 kg person in the country but I didn't check. To do list for Strava? Course then I'd have to pay.....

Schwalbe Ice Spiker Pro Studded Tire Review

Well I did finally wear out my original Ice Spikers. Basically the beads broke and they wouldn't stay on the wheel. Both broke in about a one month period. Of course I did ride a bit on the flat tires  - once it was really cold out and I didn't want to stop and fix it. So I just kept a ridin. Second time I forgot to bring a pump. Rode part way home until the tire wouldn't stay on the rim and then had to walk. I hate walking on a bike ride.

Not a big deal as I probably had those tires for about 10 years and they had seen their share of salt. I definitely got my money's worth. But there really is no substitute for heavy duty studded tires. You can boldly go where no man or woman (without studs) can go. Unless they walk. Actually, I can ride stuff you cannot walk.

The lowdown: I bought the 2.35x26 tubeless ready tires. With the kevlar bead they are supposed to be lighter, but at this width they are still pretty heavy. They did come with some poorly installed studs that I had to push back in. Studs are carbide of course so they last and last. Installed them with Stan's and running them at about 25 psi for my 155 lbs. I think I can go even lower on tire pressure but one step at a time.

Upon riding the tires, I lost 2 studs in the first 55 km. I was riding on mostly pavement to break them in properly. All were in the same spot, so it was probably something I did that rubbed the studs out of the knobs. I bought some Nokian studs and replaced them. Since then, no lost studs at all. Wish I had saved my old tires - the studs in them would have been quite useful this year. Given the cost of Nokian studs, the old tires were worth a bundle, just for the 300 studs or so. Something like $200!!!

Anyways, I had forgotten just how good a super studded tire is in winter. We get lots of freeze and thaw weather here in winter, so lots of icy trails. Any good knobby tire works on snow, but these work on ice as well. These tires really do allow me to blast downhills that I would be very nervous about with unstudded tires and would not enjoy at all. And ride up hills that I cannot ride with unstudded tires. Almost as good as summer, although I am still a bit tentative. But lots of fun riding on days when the trainer would be the only alternative to a nice trial ride. To celebrate my Xmas present, I made a video with another Xmas present (my Gopro 2) and uploaded my vid to Youtube. A fun downhill, a couple of steep icy climbs and a flat section at the end. Enjoy.

December 20, 2014 Update - Well these are good tires, but check this out for another alternative.

A Fix For Slipping Gopro Mounts

I got a Gopro 2 for Xmas. Yay. Mounted it on my bike and every time I hit the bumpy stuff, especially the fast bumpy stuff, I got an excellent video of my front tire. I tightened her up pretty tight, tight as I dared without breaking the mount, but no luck.

But wait a minute. Isn't that carbon paste supposed to make carbon parts stop slipping? Maybe it works on the cheap plastic mounts Gopro uses? So I tried it and guess what? It works pretty well. So get yourself some paste and start filling up the Youtube servers.

Or you can buy these K-Edge beauties. I don't have one, but I'm guessing they work the way we wish the Gopro mounts work. Nice reliable aluminum. Reducing the linkages between the camera and the bike is another big plus over the Gopro mounts. Google and ye shall find.
