Front derailleur broken?

[jon.mithe]

lol no, thats a little face of despair. Managed to of saved over £800 from riding into work rather than tubing it in with an oyster travel card (less £200 for pay as you go trips, so £600) so the bike even with this sort of expendature is working out alot cheaper - so alls not bad.

I have had exactly this problem with my bike. In my case it was because I had routed the cable incorrectly where it ataches to the front derailleur. There is a small lug next to the attachment bolt and the cable needs to be routed OUTSIDE of this before being bent round and held by the clamping bolt. See the instructions on the Shimano website (Page 3 figure 2)

This gives it more mechanical advantage. Judging by your photo you have routed the cable between the lug and the bolt as I did (it is hard to be sure because you have taken the photo from the other side of the mech).

Hope this helps.
