Do you think that disk brakes will be the standard brakes on cross bikes in the future?

Sincerely,

standard? no, more popular? yesclimbo

I'm sure they'll grow in popularity but I don't think they'll be standard, maybe in about 5 years or more. I would get them if comnpatibility with frames was available but it's not right now.

Considering building up a cross frame and changing some of my MTB components to the frame, what (inexpensive) frames are disc brake compatable?

This Kelly frame is the first I've seen using Avid mechanicals. But some of the small frame builders might be able to this too.

i had built up a cannondale bad boy, which comes with discs and 700c wheels on their mountain bike frame, with hayes mechanicals, and it worked great. if you're talking about switching your discs from your mtn bike to the new cross bike, don't forget about the possibility of trying to get 700c wheels with disc hubs for you mountain bike frame. of course, this all depends on whether or not your frame will fit the wheels, but the brake alignment isn't an issue with discs at the center of the wheel. then you could throw on some drop bars, and you could ride cross without getting a new frame.

Sure, it is doable, I did it even with brakeconverters to make my V's work with the higher rims. But 700c wheels in a MTB, do you realise that the BB hight will be some 1.5" higher? This, while a crossbike has an up to 1" lower BB than the average MTB.
My converted MTB with 700c wheels felt like a full-suspension bike to mount on, but there was no sag. This much higher position did not affect me much, maybe because of my 6'4", but perhaps a shorter rider will have difficulty balancing in the technical stuff.

For discs, maybe HYDRAULIC Hope's are an option. although I've been told that they won't be making them due to capacity problems, I saw them on the Morati stand at Eurobike last weekend. Normal STI's, mech-hydau converters under the stem, and the feel of the brakes was truly that of a good hydraulic set. Incredible!

I am currently using Formula B4 disc brakes & would use them as well. Would not opt for a 700 cc wheelset, just use some 1.5 26" tires on my current wheelset. Just trying to locate what cross frames are available that are already disc brake friendly.
probably never standardEricM

I don't think they will every be standard at least not untill they become faster to change than a cantilever. In a cross race you have to be able to get the wheel off and have a new one in in seconds.
They've been faster to swap than canti's for me.jw25

Canti brakes : release cable, undo QR, remove wheel, replace wheel, close skewer, squeeze brake arms together, reconnect cable.
Disk brakes : open skewer, remove wheel, replace wheel, close skewer.

A little bit longer for the rear wheel, but swapping disk wheels should be faster, and since they can be ridden when out of true, the need to change them while racing may decrease.
