CX w/ Road Calipers?(4 posts)

CX w/ Road Calipers?Gripped
Nov 27, 2002 11:18 AM
I was going to try out a cross race to see if I really like it. The weather should be dry -- high pressure is holding steady over the PNW. I figured that I would put a cross tires on my Trek 560 (circa 1988) and give it a go. Since it won't be wet, I figure that standard road calipers should stop me okay. What does convential wisdom have to say?

I suppose I could try to scare up a 1" threaded steerer fork with canti bosses and throw that on the Trek. I think I have some old cantis laying around in the garage. That would improve breaking power in the front.

On another note, the 560 originally came with 27" wheels so I have less clearance with the 700c wheels under the rear break crossbar (side to side has plenty of clearance) so I hope that cross tires will fit.

it's not stopping power you should worry about. it's clearance for the bigger tires. most calipers give very little room for bigger knobblies

If you've got the clearance go for it. I'm going to try it with an old set of Campy speed modulators with a pad upgrade on a lugged 531 road bike.

I used my Lemond Zurich road bike 2 weeks ago for half a race (until I crashed and had to switch to my cross bike in the pits cause my left STI lever was all wonky). I had only a little problem with tire clearance- was running 700x35 tires, there was one section of sticky mud only 3 feet long followed by loose gravel. A couple of times some leaves or stones ground away for a while before letting lose. I had plenty of stopping power, which was basically not needed on this course. Probably could have raced w/o brakes, now that I think of it. That would give better clearance. Just kidding. Don't try that unless your course is really flat.
