Also the bloke I bought the bike from was a bike shop mechanic and he set the bike up before I bought it, and the front shifter didnt work then either, I just thought it needed adjusting but now Im not so sure, perhaps that's why he sold it. My fault for not asking him about it, doh! I have read up on 105 shifters and compact chainsets and it appears the earlier ones did have issues changing up and down on a 2 ring setup vs a 3 ring set up so I might contact Shimano and see what they have to say, it might be that Ive got one of these dud shifters and just need to change it, if the design's fubar then I wont be able to repair it anyway.
