Hydraulic disc brakes for use with sti road levers.

Plod

I thought these might have become available by now but as far as I'm aware nobody makes them.

nicklouse

nothing mass produced.

Canyon did a proto build with some.

there have been some wire operated things made to operate some Hydros.

Nope nothing attainable yet.

If you've had a keen eye on the CX scene you'll ahve seen that some German dudes make a cool junction box that can fit under the stem which converts cable pull into hydraulic master cylinder pull.

Killer idea but like nicklouse says, nothing mass produced.

(Nick if you have louses you should get de-loused - har har har...)

Well, manufacturers should read this then set about designing and manufacturing some. Surely there would be demand and no just for CX.

I don't rate disc brakes for road use. Unless you're a tourer with a heavy bike, or maybe a tandem.
I've used Juicy 5 disc brakes on my commuter for a while now (21 lb S-Works MTB frame) and the pads quickly get covered in all sorts of road grime, oil and other 'orrible stuff.

Then, due to not braking as much as I do on a MTB, the heat never really gets into the pads to burn it off. It ends up as a vibrating, screeching event, with little stopping power. New pads work OK for a bit, but quicky grime up.
Also, the amount of rubber from the skinny tyres I have on it are the limiting factor on how quickly I stop.

Not convinced!

Oh, fair enough...

I reckon for road/commuting/cx use full hydraulics would be slightly overkill - a decent set of cable actuated discs would be more than enough power to lock up both wheels in any conditions - i'd like to see lightweight cable discs on road bikes, spoken to a few folk with disc equipped cx machines they use for commuting & they love 'em!

The Canyon concept Nick was talking about had twin 120mm discs up front to compensate braking forces twisting the forks, think Canyon also patented the shifter housing contained brake reservoir technology too... looks like this:

Other way round for me- after getting through countless rim brakes pads and a set of rims commuting to work all winter on the roadie, getting a pompetamine that runs discs is just fantastic. You have to be a little more careful with the power, but I can now stop when I want to consistently in all weathers, which wasn't always the case before. Also, I haven't had to do anything to them in the 4+ months I've had them, which fits the commuter bill perfectly for me. I'd love some sti hydros.

I was trying to figure out if you could mount the cylinder in the hook of the bar, under the hoods, with a push rod coming through/round the bar, rather than trying to package them all up front. Never quite got round to trying out any cadding though.

Not a roady, would love a time trial bike just because they look cool, but the main benefit would be to allow wheels to be designed differently without a braking surface. Also roadies could ditch a lever and go for a CBS like system as found on most honda bikes.
