    As has been mentioned elsewhere, Canyon may stipulate that bikes that break in use are hidden from the public to avoid bad PR.

    Remember when the DS chainstay on Cadel’s BMC snapped in the TDF? Not a good look for a major CF manufacturer.

      Great quote! ;)

  • RayG

    The broken bike is also the most likely reason the mechanic had the saddle and seatpost in his hand. That headline wouldn’t have us clicking on the story, though

  • Baz

    Clickbait much?
    Motorised bike theory is bullshit. As everyone has said, broken bike made PR for the brand. Of course everyone wants to be on the wagon of the motor theory as it’s a good story.

    • La Gazzetta, who showed the video, reported: ““Vuelta, bikes and scooters? What was there to hide in this bicycle mechanic of Movistar.” This story explains that this was probably not the case, and that a broken bike is the reason.

      • Hugh Davis

        I feel its pretty unfair to accuse CT of clickbait. This is the one of most “clickbait”ish story they have posted, and it is still super informative. Not to mention 200 less bait filled than 99% of other sport reporting articles.

        • Thanks Hugh. I think that the definition of clickbait is in question here. Creating catchy headlines has been around since the creation of the press, however clickbait is a headline that promises one thing, and doesn’t deliver on that promise. In this article we referred to “motors in bikes” because that’s what La Gazzetta had reported, and we tried to put further explanation around. Perhaps we could have used a headline like “Movistar hides broken bike” but all the conjecture around this topic had to do with hiding motors and is what warranted the title.

    Bugger, the clickbait got me !! CT ..you’ve gotta drop a “thug-life” parody into the bottom of these articles, totally taking ownership of the industry move to this kinda article. You may as well have fun with it :)!

    I now wonder whether the broken frame is a consequence of not using a torque wrench. Having seen a lot of footage of pro mechanics assembling bikes, I barely remember seeing a torque wrench in any of those videos… Anyway, would be interesting to see some statistics about broken CF frames and relating them to the weight of frames. I suppose that these very light frames of today must be more suspectible to material fatigue than CF frames produced 3-4 years ago? I wanted to buy an Aeroad frame soon, but having seen this makes me only wonder whether selling my “old” Dogma 60.1 (which is definitely a heavy frame by today’s standards) is actually a good idea… Taking into account how much abuse that bike surived, and is still in pristine condition :)

      I use a torque wrench and/or one of those torque-keys, but really, once you’ve become used to what 5 or 6 NM feels like, you can get away without it. The window of tight enough, but not too tight, is reasonably wide for most things. The exception is seatpost clamps where you might need to be right at the maximum to prevent slippage. A bit of carbon paste helps a lot there.

      Last week I broke yet another metal bit (aluminium handlebars snapped while just riding along), but I’m still yet to break a single carbon thing in over 20 years of riding carbon frames.

      I’m sure that’s what the marketer (can’t really call them the maker as I doubt there’s a factory in China with a “CANYON” sign out front) will claim. Reminds me of the guy who told me about his plastic fork snapping into pieces and the marketer blaming it on his filing off the lawyer lips from the dropouts! They paid his medical bills and gave him a new bike, but insisted he’d somehow caused the failure….despite the fact that the front wheel was still securely attached to the broken-off fork blades. Personally, I believe most of the pro team mechanics have enough experience that torque wrenches are overrated in importance – all those warnings are for liability issues and the ham-handed garage guys who seem to believe more force is always better when it comes to securing fasteners.

      • jakub

        Well, that’s not true, you can’t gauge what 5 or 6 Nm feels like. There was a test being conducted at one of the bike expos where people had to guess a specified torque. Out of many particpants (30+ at least, including experienced mechanics) there was only one person that got it right. The variance was huge in both directions, with many people overdoing the bolts in excess of +/-10Nm. As an applied statistician, I can tell you that the fact that only one person got it right was not due to his skills, but merely by chance.

        • Larry @CycleItalia

          First, how many PRO mechanics took this test? As an “applied statistician” you should readily admit attendees at a bike expo are not a representative sample of the pro mechanics who assemble and maintain pro team bikes but rather those “ham-handed garage guys” I mentioned the industry fears – hence the dire warnings.
          In three decades of wrenching on bicycles and with plenty of framed certifications on my shop wall, I can remember just ONE instance of my own error in this area. My own fault for sure as I failed to notice that the fastener I was securing with 4 mm hex key was TITANIUM. It snapped off under torque that a steel fastener of this size would normally require. While I quite often use a torque wrench on these tiny fasteners (more for the client’s peace of mind than anything else) I routinely secure similar screws on my personal machines without one, though I will admit I DO test my “feel” against a calibrated torque wrench from time to time. I’d bet a survey of pro-level mechanics would reveal the same.

        • winkybiker

          Like I say, I generally use a torque wrench or key, but if I don’t have it to hand, I feel confident enough that I’m not over-tightening my bars or seatpost clamp.

    • Chris Garrison

      It’s entirely possible to make a light carbon bike that isn’t fragile. Carbon fiber has an infinite fatigue life, so within a certain range of flexibility, it should be able to flex and return to form without danger of cracking or failing. This is one of the things that separates it from alloy frames. The cracking or breaking is usually the result of something other than fatigue. It could be that the frame isn’t constructed well enough in high stress/high flex areas of the frame to withstand the amount of flex to which it’s subjected. This is the trick to making light carbon frames. You can use less material in the low stress areas of a frame, but the high stress areas still need to be robust. Even in these ‘thinner’ parts of a tube, a sharp-edged impact that’s hard enough to damage carbon would also damage alloy to the point that over time, fatigue would be a factor in the frame’s demise (think soda can that has a dent that you can break in half by flexing it).

      • Sean Doyle

        Not to be pedant but “Carbon fiber has an infinite fatigue life, so within a certain range of flexibility” most materials if you only flex it within a certain range of movement has a ‘infinite’ fatigue life. It has been shown if you flex carbon enough and often enough it doesn’t lose some of it’s internal bonding and soften.

        • Chris Garrison

          Alloy frames will become more elastic over time. This is why bikes often feel ‘noodly’ after a period of use. Sure, the quality of the resin used in carbon frames is just as important as the carbon strands itself, but providing that the resin in the laminate, and the epoxy used to bond the joints, is high quality, a carbon frame shouldn’t develop the relaxed ride feel that alloy frames will.

          • Sean Doyle

            Sorry, you are wrong on this alloy frames do not go soft. Steel frames do not go soft but carbon frames actually can go soft if not designed properly.

            • Chris Garrison

              Alloy frames absolutely have a fatigue life. Does that mean it’s not possible for an alloy frame to last forever? Of course not. If that was the case, aluminum wouldn’t be used to make airplanes. But, the multitude of stresses placed on any alloy structure can limit its endurance if other variables aren’t considered. The ‘softening’ of a carbon frame is not down to the strands of carbon within the laminate itself, but rather subpar resins. The resin material is just as important as the quality of the strands themselves, but it is often overlooked in any discussion about carbon frame quality. Poor resin is like having great alloy tubing, and really terrible welds.

              • Sean Doyle

                Every material has a fatigue life. Even the often touted ‘infinte’ fatigue life of Titanium can fail if not designed properly. Dont confuse fatigue life and going soft. Not the same thing and going soft does not exist in the alloy metals used for bike frames. Whether it be aluminium, steel or titanium. This is where marketing has confused people. Every material when designed to operate with in its range will last a long time. Resins make up the carbon composite and like you said you have to take into account each variable and engineer the product so tha the materials are used appropriately to ensure longevity or maximum oerformance but dispisable.

  • Tim Rowe

    Hard to believe people even chose to report on this conspiracy theory idea. Hell, when we see broken bikes at races, it’s out of common courtesy that we don’t go taking photos etc, as much as they might make for interesting discussions and stories. Manufacturers don’t need that kind of stuff going around out of context.

    • Dave

      Hard to believe people even chose to report – but not hard to believe that La Gazzetta chose to report on it!
