Ronster Posted March 30, 2010 Share Howzit Guys, I have a raleigh team frame. The frame is made to take a 34.9mm deraileur front clamp with a 53t chainring. However I would like to put a 55t chainring on as I'm converting the bike into a tt from. The frame gets wider towards the seat post and therefore I cant move the front deraileur up as it doesn't fit. I can however do some mods to get the deraileur to fit by just skimming the inside of the clamp, but my question is would I crack the frame, as its not meant to have a deraileur that high? Thanks Link to comment Share on other sites More sharing options...
techguy Posted March 31, 2010 Share I think it'll take more than a bit of skimming to make it work, and there's a strong posibility of cracking the frame as where the FD sits is normally reinforced to take the load of the clamp. A 55 chainring is also a bit enthusiastic... Link to comment Share on other sites More sharing options...
Ronster Posted April 1, 2010 Share Sorted. For some reason where the bike shop thought the deraileur was meant to go was actually an indent to accomodate a triple chainring. The deraileur fitted further up where is is meant to go but needed a bigger bolt. For some reason the frame is abnormally wide, in fact wider then spec.
