This here is one of those posts I started to draft during the past summer – during the 2011 Tour de France, to be more precise – but then put aside.
One of the more notable trends in bike design at this summer’s Tour de France (2011) has been the proliferation of intensively engineered time trial/chrono bikes. With Evans winning aboard a BMC, that bike clearly got a lot of attention….but BMC was not the only manufacturer rolling out totally “bespoke” chrono machines. Custom chrono machines is, of course, not a new trend. What distinguishes this batch from prior years is the attention going in to integrated braking solutions. Google Evans’ BMC chrono bike and you will see: they’ve been working to integrate traditional calipers into the fork and seat/chain stays such that the brakes are almost invisible, save for the arms and brake pads.
Now, it appears that this approach is shifting over (at least for a couple of manufacturers) to traditional road frames as well, of which the Ridley shown below is a prime illustration:
Now, don’t get me wrong here: this is an amazing piece of engineering and problem solving, in my view.
But, mark my words here: in only just a few years (2015?), this bike will be viewed as a joke, a kind of last gasp of an earlier paradigm that is now completely outmoded. This bike, in other words, will be regarded in 5-6 years as Lance Armstrong’s ’99 TdF winning Trek was regarded by the time of his last TdF (2010) entry: an odd bird and kind of joke. [Armstrong’s ’99 bike, you might recall, was a Trek carbon frame, but with a 1″ threaded headset and a massive (albeit pretty) Cinelli quill stem. This was essentially a cutting-edge carbon frame, brought down by a sizing standard that had prevailed for decades; Trek probably managed to shave close to a pound from the bike in the next two years simply by shifting the headtube size and moving to a threadless setup]
These integrated braking solutions are the sine qua non that the limitations of the rim brake model have been reached (or even exceeded). Rim brakes must die, in other words, because the “best minds in bike engineering” are having to spend their time on stuff like this in order to keep rim brakes alive. Designers and engineers are turning themselves inside out to find a way to disguise and deal with rim brakes….all while the totally obvious solution is right in front of their eyes. Dump the rim brakes, dump the cables, mount a tiny hydraulic disc back there in the junction between the seat and chain stays, run some internal hydraulic lines that need no service, and you are done. Same with the front.
If I had any insider connections to “the biz” I’d make some ambitious prediction: 2012 will see the first TdF chrono bike with hydraulic discs. But, I don’t have any idea what goes on inside the biz, so I won’t be so bold. However, in subsequent posts – on Eurobike and Interbike 2011 – I’ll harp on this “so obvious the manufacturers can’t even see it” argument a bit more.
