Road Bike Disc Brakes: Latest Roundup

The whole “hydraulic disc brakes on a road bikes are inevitable” thing that we have been bumping here on BB for some time now has, it seems, crossed some sort of critical threshold in the past couple of months. As well it should. The tone is shifting from, “here is a crazy idea that might work” to, “this is going to happen, but when will SRAM or Shimano get off their asses and make a hydraulic road lever?!” This was most recently illustrated by Velonews’ general article on road discs, by Caley Fretz. His conclusion:

Without the availability of a hydraulic road disc, this is all conjecture. There are far more hurdles to be overcome, too many for this space.

That said, with every innovation comes the inevitable “my gear is just fine” argument. Friction shifting was satisfactory, as were six-speed indexed downtube shifters. Single-pivot brakes were great in their time. Eight-speed Shimano STI was phenomenal.

We never realize what we have is inferior until its (superior) replacement becomes commonplace. Mountain bikers will never go back to rim brakes, roadies will never go back to downtube shifters. Ten years from now, perhaps we’ll be wondering how anyone rode with those old dual-pivot rim brakes.

Yup, pretty much the BB party line.

Here is a little bit of a link roundup, highlighting a few of the fairly recent contributions to the ongoing discussion:

  • CX Magazine just now put up a little piece on Tim Johnson’s disc-ready Cannondale cross bike. The Cannondale fork is quite nice as well:

  • Last, but most intriguing, is this update to the Volagi from Procyclingnews’ Interbike coverage. I mentioned Volagi quite a while ago as I somewhat randomly came across their site very early on (in the life of the company) – you may recall that they are building a brand entirely around a platform of disc-only, full carbon sportive/gran fondo/”comfort” frames with all mod cons (BB30, tapered steerer maybe?). If anyone had incentive to grab one of these Macgyver-ish cable-to-hydraulic converters (that we’ve linked to here on BB in the past), string it together with some high-end gear and roll out a pro-style hydraulic disc’d road bike, it was Volagi. Looks like they’ve done so, and looks like Pezcyclingnews has it on test. I’ll keep an eye out for the review. In the meantime, here is a pic:

Hydraulic Road Disc Brakes: Shifting Update!

Following up on my post on Di2 shifting options and the Fair Wheel Bikes Di2 hack, I’ve looked a bit longer at the Calfee Design Di2 battery modifications displayed on a titanium frame from Vuelo Velo. Looks like Calfee has actually been doing this for a few months now and can also retrofit other carbon frames for the internal Di2 option. Here is the core of their kit:

Also turns out that my old buddy Mike is now working on promotional type stuff for Calfee…and his brother and other buddy, Ian, owns a shop in Waco, Texas that is taking delivery of some really nice Calfee rigs. Ian’s own personal bike is simply incredible – not to mention WHITE! – and employs the internal Di2 setup. Apparently Ian will also be on Calfee’s new “Adventure” frame for gravel road riding as well. Take the following as a teaser; he’s got gobs more photos on his shop’s site…but that white Specialized crank setup (on a PressFit 30 bottom bracket, I would assume) definitely warrants a picture here on BB:
