View Full Version : Disc brakes: possibilities for further evolution/refinement?

I suppose this really is only known to the engineers inside the Big 3, but my general impression of disc brakes so far:

-Bulky levers. Getting better, and maybe resolved w/ electric shifting but for purely mechanical shifting, still a big "horn" and longer reach on top the shifters of all the different groups

-Some wonkiness in terms of rotors under heat warping and rubbing on the calipers

-general clunkiness of the hoses and reservoirs.

-Slightly heavier in terms of componentry

-more flexibility in wheel design/components

-possible design trade-offs in the frame - beefier/heavier?

-Some minor rattling/clicking depending on how warm the rotors are.


Overall, though the braking does seem "better" overall, although noisier...


However, this is really the 1st gen where all 3 main component suppliers have disc brakes as part of the main lineup (sort of...). I'm wondering that with the next few generations of groups, are we due for a massive refinement on road disc brake groups? Can we expect a dramatic improvement in weight, refinement, etc? Or are they mostly a mature tech from all the R&D in MTB component technology?

We're likely to see refinements rather than wholesale upgrades from here out.

Take a look at moto stuff for examples.

Stage 18 of the Tour

15:56:56 CEST

85km remaining from 171km

Hayman flats in the break. He's on disc brakes and so it takes the mechanic a fair bit longer to change the wheel.*

His day out front could be over.

My guess is something needs to be done about that...

-Bulky levers. Getting better, and maybe resolved w/ electric shifting but for purely mechanical shifting, still a big "horn" and longer reach on top the shifters of all the different groups - Not true, campy reach is about the same. Its whole thing is barely bigger, it also gives you an extra hand position which is pretty cool

-Some wonkiness in terms of rotors under heat warping and rubbing on the calipers - this still happens for sure, I bet will get better

-general clunkiness of the hoses and reservoirs. - hose is like a cable, new bikes have pretty much hidden all the cables. Its not that bad as is.

-Slightly heavier in terms of componentry - yes, its a lot heavier, this will come down I am sure. That said, you can get a disc brake bike at UCI weight

-more flexibility in wheel design/components ok

-possible design trade-offs in the frame - beefier/heavier? - disc frames are really light still

-Some minor rattling/clicking depending on how warm the rotors are. - never experienced this

As in MTB, the expensive stuff will be nice.

Actual bulkiness is due to mechanical shifting. Wait until you see Di2 105 or whatever. Res and caliper don't have much to them. The game changer is tire and rim size when you're not constrained by a rim brake. A roubaix is basically an anyroad as a result

With road/gravel, probably see some sort of trim adjustment to combat drag and wheel change on the shifters/levers. Metal matrix/carbon disc technology like the race cars and the most out there thinking and wouldn't be surprise to see some sort of anti-lock system since electronic is making its way already in cycling. Also experiment with rotor sizes.

I think we're going to see incremental improvements in the component that won't require frame changes, same way that STI shifters have gotten way better in the last 20 years.

I think the more interesting question is whether flat mount or post mount will win in the end. I doubt we'll see a 4th standard (IS tab already having lost for the most part).

flat mount already won when it comes to road. All the new road bikes are coming in flat. All the new groupsets are flat (not sure about sram but campy and shimano are flat)

Heyman made it back into the break.

Once refined, I think the future is positive.

Maybe better hydraulic brake decouplers for travel bikes where you split the cables? This has to be a very niche market, though.

How much refinement do you think there's likely to be? These brakes have existed in the MTB world for decades. And the seals STILL leak.
I'd be much happier if TRP refined the Spyre caliper.
