frame conversion- mtb to CX?(3 posts)

frame conversion- mtb to CX?bk19
May 2, 2003 11:36 AM
Having a road frame converted for CX use is fairly common, but I don't know if I have ever heard of anyone converting an mtb frame for cross use (700c tire). It would have better tire clearance and longer chainstays than a road bike, so it would be better suited for conversion. I would think all that it would involve is moving the canti posts and maybe the brake bridge. Am I missing something? Would the rest of the geometry be screwy?

I already have a 26" drop bar bike that I use for commuting and for one CX race, but that spare 700c wheelset is begging for some knobbies.

main issue with MTB to cx is top tube length. MTB's have long TT's so when drops are added they tend to overstretch. some of the chainstay lenght will be negated (abot .5") with the addition of 700 wheels. You are correct with the rest, just buy a 700c fork and make adj. to rear brake issues and you are ready. with 700's it will also increase your bb height and decrease standover by same .5".

longer 700c fork will slacken both head and seatube angles making bike possibly too relaxed.
