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:

Good News/Bad News: Di2 11-speed And Disc Brakes For 2013?

Cyclingnews is reporting today a number of insider rumors on the next iteration of Dura-Ace and Di2. Shimano might finally jump up to 11-speed cassettes, which is not that surprising given Campagnolo Some of this is the obvious stuff you might expect, namely that they will be “harmonizing” Dura-Ace with Ultegra Di2 so that the systems would be interchangeable and D-A would use the better wires and harnesses.

They note:

Indexing control will supposedly be moved to a front-derailleur-mounted microprocessor, turning the levers into ‘dumb’ switches that merely send binary signals – just like on the recently introduced Ultegra Di2.

What is interesting here is that this clearly sets the stage for a “controller” paradigm that we’ve been talking about here on BB: with the “brains” moved to the derailleur units themselves, the actuators on the bars (or elsewhere) do become “dumb” switches. As we’ve also been saying on BB, this frees up space in the levers and it appears Shimano will be using that space to integrate a disc brake option as well.

Sounds like the disc option would be mechanical in the 2012 year, but maybe hydraulic by 2013. Can’t wait to see what Shimano would do with a high-end road hydraulic caliper, though it sounds like another year or two before we see that.

The bad news in all of this, though, is what will become of Bliggity Blog once I can no longer pontificate about hydraulic disc brakes on a road bike. Maybe then I will move into advocating for internally-geared hubs on road bikes. Or, I could actually write more about the state of the world, the collapse of global capitalism and the future of market-based socialism. Time will tell….
