Hydraulic Road Disc Brakes: TRP Hywire Edition

No sooner had I spoken about being behind on the hydraulic brake lever news than another round of information on this TRP system pops up. I guess it is the TRP “Hywire” that will integrate with either Dura-Ace or Ultegra Di2. Bike Rumor – which somewhat out-of-the-blue has become a favorite destination for tech-ish info – has some interesting shots, for instance:

While this is neat to see (as it becomes more production’ish rather than purely proto)….is this not just a brake lever with the Shimano “satellite” Di2 shifters glued on?!

And, from the front:

This last angle is most interesting, for it demonstrates the big advantage I’ve been pointing to in my earlier posts: that is, the more you can pare down specific parts to a single function (or fewer functions), the more refined they can be for that specific function. In this case, the lever here only needs to function for braking (at least in as much as the shift buttons are placed in a reasonable position). No need for the brake lever to also initiate shifts and so forth. And, if the brake lever is really about braking, then why not radically reshape it to maximize ergonomics for braking from the hoods as well as the drops? Not very pretty, I’ll admit, but definitely demonstrates the great potential with this approach.

If you want more shots and information, Bike Radar has also posted an update on the system (including the calipers they have paired with these levers).

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….
