probably daft, but after seeing that HOPE thingmybob/contraption to convert cable pull to hydraulic, why hasnt anyone ever developed some hydraulic disc brake, cable pull gear levers for CX bikes, or have they? the reservoir chamber on my elixirs is small enough to incorporated into/onto a standard levers.
Is it only a matter of time as disc brakes havnt been allowed for that long on CX bikes?
Mainly because virtually all CX riders ride with STI levers of some form. The creation of hydraulic STIs would be a mammoth task and only SRAM or Shimano I think would touch it.
Bodging with an adaptor is an easier task which would be retrofittable and substantially cheaper!
but why couldnt they create a hybrid sti lever? Not hydraulic sti's, but hydraulic brakes incorporated into sti levers?
I probably have a fundamental lack of knowledge of how sti brake/shifter levers operate, but it was just a thought?
EDIT: Maybe i should patent that idea.
Too complicated. Besides, the whole point of CX brakes is that you don't need to stop, you just need to slow down enough to leap gracefully off and shoulder your bike in one smooth fluid movement. 😉
Well Shimano did that for mountain levers and it had some fans, although a lot of people didn't like it... I doubt if there's a big enough market for a roadie version.
Probably because mini v-brakes are more than powerful enough to stop a CX bike.
It would still need a lot of investment to turn the braking part of an STI lever to hydraulic and I'm guessing if SRAM/Shimano aren't already working on it it's because they see it as too small a market to be worth it.
There's already a lot going on in the STI/Ergo/SRAM brake/gear levers.
All that's concealed in a tight space, and the part of the brake it's all in is also used to hold onto. Adding hydros wouldn't be a problem, but it would probably render the lever as useless to hold onto.
I assume the remote master cyclinder is the way to go.
Happy with cantis for racing.
I am sure it will happen, but disc brakes have only recently been allowed in cyclocross. It's rumoured that the rule changed because a major manufacture has something in the pipeline.
Most of the people I race with are not that excited about getting disks, as they just use old road bike kit which will get wrecked after a season of cross. You can use all your existing road bike wheels with cantis and they are generally considered good enough.
So you are looking at a subsection of an already small market.
Same here, no one I know that races is interested. With a top ten rider still wearing out his old Sora, you'd have a job convincing him that he needs discs.
I don't see the point of system like the hope one. As you still require cable quality to determine braking quality.
A good set of cable discs like bb7 with decent cables and levers will be lighter and work as well.
Oh yes, just thought with electronic shifting coming in at more affordable levels than before, I think that there will be an electronic shifting with hydraulic disc groupset on the way. It would be good for cross, monster clearance, nice carbon wheels with no braking surface, and no cables to constantly be cleaning and changing. I would love to get ride of cables but I'm not sure that I'm going to be going out of my way to save for such a replacement.
Slight thread resurrection but this article over on road.cc:

(scroll down a little bit) show Hope's new device for converting normal road STI's to pull hydraulic disc brakes.
Looks like Paul Oldham will be riding it at the Three Peaks...

No he won't. His frames aren't disc compatable (yet) The owners of Hope (Ian and Simon) will be on it though.....

No, they won't. you think Hope have just got this adapter sorted and thrashed on a pair of M4 calipers and 200mm rotors??? The full version in the end is likely to have a slimmed down caliper with smaller pistons, 120-140mm rotors with thinner brake tracks. Don't forget this adapter is just a prototype.

Yes but you still (unless they release a sti lever) need the cable to determine the power of the brakes. You can use a powerful calliper but you still will have the drawback of a cable operated system. All the added adapters and reservoirs adds to the weight which you wouldn't have if you went will a solely cable operated system.
A fully hydraulic system is a different mater.
finally someone listens to me....
It's on the cards for 2013, apparently. Every roadie who says "naaah, why would I want discs?" will rush out and buy the system because they are fashion victims and won't be able to resist the industry hype.
Triathletes will, and your MAMIL types will, but I suspect most dyed-in-the-wool roadies will be far more reticent.
Not fussed myself!

AS soon as they are in the pro peleton I bet the roadies will be tripping up over each other to buy them, after 18 months of "Ooh I don't like the look of them, I bet they don't work" etc.
