Avid has introduced a new road specific disc brake system. The question is, has anybody used any disc brakes or combination disc / canti. on their cross bike? Comments appreciated.
I would imagine discs to be perfect for crossAlexR

The mud clearance and the great emergency braking should make discs perfect for cross. I've got a bianchi DISS with Avid mechanical discs and the difference between these and V's is night and day - and from what I hear hydraulics are an additional order of magnitude better.

If there are no hidden downsides and discs work as well as they do on smaller wheeled mtbs, I say go for it.

What aboutmuncher.

Bend a disc in a tumble and you are stuffed (not that I have ever done that, but it happens apparently). And extra weight of course, for those that care.

Are fast wheel changes harder or easier with discs?

At least with my Avid mechanicals. There is no quick release to be disengaged for the brake caliper to open.

And as far as bending the disc - they are pretty well protected by the stay or the fork leg.

Fragility would not be an issue on a cross bike. I have been racing Downhill for a few years, and have never harmed a rotor in that time. I have had some nasty nasty spills in some of the most jagged rock courses, and my rotors are still straight. The rotors are actually in a more safe location near the hub than are the canti's up on the stays. Plus, for those of us with big gangly feet, we no longer have to deal with our shoes or calves hitting the brake arms. There are a few companies already making CycloCross frames ready for disc. I know Kelly Bike Co. has made a disk version of their cross frame, and probably would make a custom ready to go if they don't already. Indy Fab is another place to look.

My 'cross bike came with the frame set up for disc brakes. I have added mechanical discs as road bars will accomodate them. They have been a great upgrade as I have had hydraulic discs on my mountain bike for the past two years and can't even imagine struggling with anything less. If the marginal weight difference isn't a problem go for it...I've never had any problems with them.

What 700c wheels do you have that accommodate disk hubs, and do you get one finger type braking with road levers?

Any hub will fit a 700c rim with the right spokes.

Hope has a converter kit, mech to hydrau, which is mounted under the stem. Gives a true disc-feel. I saw this system on a Morati bike with STI levers and Hope Mini discs. From the way it felt on the stand at the bikeshow, I'm sure 1-finger braking is possible.

Guys, what do you think? Will fork scattering be less with discs, or more? I hate it on both my bikes, makes it hard to keep control under hard braking.

Very good to know,I am anxiously awaiting the new Avid road disc system to be used on a custom (Strong) frame. Thanks

Will be following the posts to see how the Avids work.
I would need to have disc mounts welded onto my Ritchey Swiss Cross, but have been warned that the thin steel tubing may not hold up to the added stress of discs- any opinions or experience? The clay-mud here in Virginia is very abrasive and has ground through my rims within a year (3000 trail miles), so discs may have an advantage for me.

I would like to know more about the disc brakes. What kind of bike?
I use Magura HS-66sTonyD

I just installed them recently but so far LOVE them....fantastic modulation, unaffected by climate conditions.

I also have a Bianchi DISS. I put a RockShox Duke Race fork on the DISS and for grins we put my friends Cross front wheel onto the original DISS fork. It fit like a glove so IF you guys want to mount up a 700c rim to a Disc mount hub it will work no problem. Just make sure to 3 cross your spokes as there is much more load on the spokes with a disc.

Where can I get info on these - There isn't anything about them on Avid's website. Also, do they work with STI?

Click on the Interbike virtual trade show and go to the Avid booth. They are supposed to be available by the end of December, and yes they are designed for STI levers. If you try to correspond via e-mail with Avid I hope you have better luck than I did ,they have yet to answer any of mine.
