Hello,

I recently tried to re-adjust my front mech. Ive done this a few times now and it has been fine, but Im either doing something wrong now, or something is broken! Its a shimano ultegra front mech with shimano 105 flightdeck shifters.

So I decided to fit a new cable etc. Did it all, set the low, tightened the cable, tried shifting to the highest (big ring) and it just would not go that far - even with the limiter screw all the way out. I literally tried for hours, playing about with cable tension etc, then I realised that the end ferrules going into the shifter had broken and the housing cable was pulling through - I think as a result of pushing the shifter too much to try and get it into the highest gear. So I replaced this etc, but still it will not work well.

If i set the low limiter too tight, then it just about gets into the highest gear, but it wont go back down to the lowest and vice versa. The barrel adjuster is also extremely hard to turn - think it needs replaced, but I dont think it is causing any problem.

So I am now left able to shift from low - middle - (alot of clicking) - high then back from High - low, completely skipping the middle ring. It is proving to be an absolute ball-ache and I just cant figure out where Im going wrong! Help need urgently!

Thank you.
