Am looking at specing a new bike-its a cross bike and the brake options are Shimano BR-R550 which are cantilever brakes which I do not particularly want or BR-6700 which i would prefer.

The problem is can the 6700 brakes clear a 28 section tyre which I want to use?-I know the R550 brakes would clear but have had problems with previous cantilever brakes sticking on.

Thanks for any advice.

    If the frame will take BR6700 and the blocks will reach the rims then they will clear 28mm tyres. Most CX frames would need long drop calipers due to the extra mud clearance. Best to check.
    You would not get mudguards in as well, Possibly not even Crud RRs.
    To get correct modulation with the 6700s you would need to use 6700 levers as well.
