I'm talking the whole assembly, Andy. I've seen enough trashed brake levers, bodies, etc. to consider all of the unit expendable. (I haven't priced brifter assemblies but I am guessing virtuallly all are more than the $30-80 of a good old-school pair of aero brake lever assemblies.

I was under the impression from j-a's post that these brakes could be used with conventional cable brake levers actuating a hydraulic system so the Tektros I mentioned that were simple cable only would work just fine. Now I realize I have no idea what "cable to hydraulic" means.

Oh yeah Ben, a whole brifter costs your left nut. But the vast majority of folks who would buy the Tektro would still have a brifter. For a cross bike DT shifters would be particularly awful.

At this point, dt shifters are an absolute non-starter in cross. Might as well ride single speed, you'd be at almost the same disadvantage.

This whole thing is headed toward dis-integration of the brake and shifter anyhow. Electronic shifting and hydraulic brakes. The relationship to the two will likely be that the brake pod is a piece of real estate on which the shifters go. See Cav's bike from this year's Tour. Hydro levers are less expensive than brifters (I had to replace a brifter from a crash last year - $$), so at least that's a plus.

My pit bike still has BB7s, which, to be honest, stink on a cross bike. I find them to be bad enough that my bs meter screams when anyone proclaims how much better they are than cantis. Maybe if you're using absolute crap cantis like Shorty 4s or something else, but Shorty Ultimates blow BB7s away if you ask me. I'd like to try these new TRP deals.

These are pretty good, I just built up a Pivot Vault cross bike for a client, these work very well, nice and crisp, and they don't look much larger than traditional hydro calipers. The set up was very simple, no jacking with hydro hoses, etc....
I'll have to get pics of this bike for you all, pretty nice, about 17lbs with tubes, etc...
a buddy of mine just built a Cannondale with SRAM hydro brakes, he said it was 2lbs heavier than his caliper brake Cannondale cross, that is crazy
dkri, if you don't like the BB7's, check out the Shimano CX75's, I have these on a single speed MTB, and a prototype 650b bike, these work far better than the BB7's

Gonzo: Are they an open system or closed? The literature didn't say. I assume open because closed would be truly stupid. Some of the early mountain bike discs were closed.

I have seen the SRAM hydraulic kit first hand now. The master cylinder end does not look as bulky as in photos. And I did not realize that SRAM has a couple levels of hydraulic road discs. I have ordered a Giant TCX 1 with the Force(?) SRAM stuff. I like how the Giant cross bike uses mountain width drops and a 15 mm through axle on the front. I can use my 29er wheels on it if I wish.

Stoked. The Steed Cycles riders are on these bikes and have had great success racing this fall on them. They all like them a lot and say the brakes are way better than rim brakes. Kim Steed set his up with Red and built wheels on DT240 hubs and ENVE 29er tubular rims. Totally hot bike.

Sorry I missed this. I just started another thread on these brakes, as I now have one one my bike.

I think I a call bs on two pounds more. I think there is weight penalty but two pounds sounds like something more than just the brake change.

eh, could be old fart, just repeating what he told me, he works in bike shop, and has access to a scale, could have been something more, tubes vs. tubeless?
Not sure if they are closed or open, I think closed?
The SRAM offering looks pretty good, heard about one issue of rattling levers? Who knows, I think this is pretty cool with the evolution of road discs, Shimano stuff looks really nice, but you just have to go with Di2
