I have a 31.8mm front derailleur clamp, and would like to use it for a bike I'm building, however the bike specs call for a 35mm front der clamp. I attached the 31.8 and it looks okay (the very edges of the clamp don't exactly approximate eachother, but it seems to be stable when tightened down). Is there a problem with using the 31.8mm derailleur on the 35mm down tube? Thanks.
