Just asking...?
Because there aren't many drop lever hydro's about at the moments.

To confuse the retards. 😉
Why do you think they are cross? It's because their owners dont care enough to buy them hydraulic ones of course.

Because there's no advantage in using hydraulic disk brakes on a cross bike.
Because hydro systems would boil dry trying to cope with the much higher speeds achieved in cx.
V-twin isn't a drop bar lever hydraulic brake.
Red isn't (and by the sounds of it won't be anytime soon) released.
Formula seems closest but it's Di2 only.
You can get a Hope system, which uses a device mounted under the stem to transfer cable effort into hydraulic but that's gotta be a compromise; I'm waiting for the first Shimano or SRAM fully hydraulic system. Hope tell me they have no plans to make one.

It's not really Hopes "thing" is it? They specialize in carving from aluminium and a shifter/brake is a lot more complex than that.
The SRAM ones seem to be just about there now, so doubt it'll be a long wait!
Anyone else think the brake manufacturers have been caught napping on this one?
Not that BB7s are really much of a compromise, and what will be offered will no doubt tie you into 10 speed+
Shimano have full wireless electric shifters/brakes coming soon with little electric motors to work the pistons. I'm waiting for them rather than messing about with oily stuff/cables.
electric braking? you sure? haven't heard a word about that and it makes no sense given hydraulics.
I dissolved my rear canti brake pads yesterday. Only 2 races and 3 short rides worth out of them.
Got me thinking that disk brakes may have been a good option if only for a longer lasting sinter pad option.
Anyone else think the brake manufacturers have been caught napping on this one?
Until the UCI legalised disc brakes for cross there was far too little demand for them to make a decent system.
because cyclocross bike shouldn't have "good" brakes, its the law
I'm becoming more and more tempted to swap to disks when they come in, I don't really have any issues with the power of my canti's as yet, pad wear, rim wear and clearance are pushing me towards discs.
Regarding clearance mind not many of the top pro's are using discs even they could have access if they really wanted them
1:14 for Stybars overly aggressive finish
Powers and some of the US riders were showing new Hydro reds a couple of weeks ago, even though every course seems to be some dusty dry school field, closer to SRAM for feedback I 'spose...
Don't think it will be long before they do!!

Hoping not too long before hydraulics as just picked up my new road bike a few weeks ago for commuting to work 🙂

Those Srams are unspeakably ugly. I'd miss out on my favourite position with my hands cupped over the top of the hoods too. Surely there is some way of doing something with a specific bar and using the cavity within to hold the reservoir?

I thought something similar, like hope's solution but with the reservoir/cylinder buried in the bars.
Personally I prefer the hope solution, it might be overly complicated compared to the SRAM Red but it's more compatible, cheaper to break in a crash (can you think how much hydro STI's will cost!), can be integrated with any groupset (not just Red, or if it ever happens DA).
The only place i can see it working is in the formula Di2 levers as presumably the levers are going to be cheep and compact, being just normal levers with a couple of switches?
I much prefer the Hope v-twin system to the BB7s they replaced (commuting not racing!)
A friends bodge on the CX bike

Regarding clearance mind not many of the top pro's are using discs even they could have access if they really wanted them
I noticed that. I've made the decision to go for some high end cantis for next season, and won't be opting for discs until the market forces me to.
Mud and rain have been in abundance during this years cross season and my cantis have delivered impeccable braking every time.
OP No one I know wants discs. Of the five people I know and race with all opted for catis on the bikes they bought this year
I want discs...
I have an article ready to go about why pros aren't that keen on discs (yet).
Discs are far more controllable and can be made (nearly) as light. They're coming, don't you worry. Remember when pros didn't run suspension forks because they made their XC bikes heavy? And now everyone uses them. That'll happen in 'cross in the next two years...
It's a shame that we'll have to wait 4 years for the trickle down.
I'm currently crafting something to run hayes hydros on my genesis. Sorta a home brew trp/ hope type thing.
Different to the one above but same principle

Yeah, but you only changed to pneumatic tyres last year. 🙂
Discs are the biggest technological advance since I started riding bikes. .
Not yet heard a decent argument against them.
Most anti-disc logic appears to be along the lines of:
'My grandfather's brakes were crap, my father's brakes were crap and by God my brakes are going to be crap too'.
The worst thing is that it means that last years/ years before road stuff gets thrown away rather out into the cross bike and properly killed off. It's a new standard, it means buying new wheels, new frames, etc etc. I don't want to.
Bland - how does that bodge work? I can see normal cables coming out of the bar tape, plus a pair of MTB levers in the middle. Is he running 2 sets of brakes? I can't see a front canti 😕
I reckon it'll happen, I'd go disc if I was buying a cross bike now, rude not to!
As great as hydraulic CX disc brakes would no doubt be what is so terrible about mechanical discs?
Surely a BB7 road and your current preferred STi are a step up from canti's.... No?
It's the ability to slough off mud that attracts me to discs. That and the sadness of wearing through a pair of carbon rims...
The braking advantage is not so great at races but improves off-road technical riding and fast downhill road sections in the wet. The ones I've tried have been mechanical and worked marvellously for all these uses.
I've been running mech discs on the work bike for 10 years, and I'm looking forward to hydraulics when they are available (and affordable).
The only reason hydraulics are not in use is because they have not been available. Once they are out there, they will largely displace mechanicals for the same reasons they have done so on MTBs.

Your finest work!
Been messing around with a rather tidier vesrion of that "conversion" pictured about for ages. Hindered by using ancient Hopes that are siezed! :roll:It would give me bar top levers activated by the cables. My desire is to give me decent brakes on my rough stuff bike. I do use BB7's but why not go the whole hog?
I do doubt any urgent need for them on a CX bike. After all braking isn't needed to a great extent when racing (3 Peaks excepted!)
I see the biggest use will be on those who ride dropped bar bikes off road recreationally.
Please note that I think its about time that we differentiated between CX which is racing on bikes that don't even need bottle cages let alone mudgaurd eyes and what ~I have called rough stuff which to me is recreational.
As for road use I reckon modern DP brakes are good enough to overcome grip in many cases and thus need is limited. Aero and rim weight reasons my be important though.
they will come.

er...they weigh more, are less aerodynamic, offer minimal performance benefits over dual pivots or canti's for race purposes...
One thing I wondered... For cross, do you reckon that if discs take off, that might influence the course designs and other parts of the bike spec? (tyres, especially).

why would it? seriously, most courses are based in parks and the like so only so much you can do, councils don't like there parks being trashed in wet weather for a start.
I suppose nice hyrdo drop lever would be easy to make if you put the shifters back on the downtube where they belong.
mrmo - Memberwhy would it? seriously, most courses are based in parks and the like so only so much you can do, councils don't like there parks being trashed in wet weather for a start.
There's trails round here that were purpose built for the limitations of cross bikes, so if you change those limitations presumably that'd change the designs.
TBH I'm not sure if any of that's desirable, seems like it just ends up narrowing the gap between cx and xc... But I can easily see it happening.

this is the thing i think most people know what a cross race means, add in UCI guidance and we have what we have. Consider too that trails and race courses aren't the same thing.
Sorry, could have been clearer there, these were built for use in race courses (not sure anyone builds trails for any other reason for CX?)
I'll happily use discs one day, but I hope the evolution is slow. I like many that only ever race their crossers are more than happy with cantis.
I do begrudge a little the fact that CX discs are being championed by those that want a cross bike to emulate their mountain bikes. The brake issue never had a voice, all was well until the bandwagon rolled into town. You can't argue that discs coincide with the increased popularity with the 'ownership' of cross bikes.
The pitch I feel is being queered by those that will never venture out onto it.
That said, give me a super lightweight set of hydros, chuck in a new frame and wheelset for free to put them on, I'd happily get on with it.
Building a Kinesis Crosslight pro 2 at the moment .
going for bb7 road .
i use bb7 mtn on the mtb so will be good to have same pads .
shame that bb7 road are so expensive compared to the mtn version .
Hence me wanting a division between CX which is racing and everything else.
Actually that's a good point the UCI rule change that has sort of triggered the current push towards discs in CX (rather gentle compared with other cycling industry technology/marketing pushes) was probably brought about more by cycle industry pressure than rider demands.
Those consumers with the most interest in disc braked CX bikes (including myself) would probably use such bikes primarily for recreation and commuting before actual racing...
The slower, patchier adoption of discs by serious CX racers suggests the perceived benefits are more towards the commuter/leisure rider (already used to discs on his or her MTB) than the serious competitor who isn't keen on a heavier stopper when the extant bit of kit does all that they need for ~200g less...
I still fancy a disc braked 700c wheeled bike but I doubt I would do much actual CX racing on it...
