Problems with front derailleur.
#1
Hi
I have just done a complete overhaul on my wife's mountain bike, here is a list of what I have replaced;
Shimano MF-TZ 31, 7 speed 14-34 mega range cog set.
Shimano FC-M 171, 48\38\28T Chain set.
Shimano RD-TX35 6\7 speed rear derailleur.
Shimano FD-TX51 front derailleur.
Shimano CN-HG40 Chain.

I have adjusted and indexed the rear mech. The problem I have is with the front mech, I can change from smallest to largest cogs OK but when I change from the largest it changes to the middle cog fine but will not go to the smallest cog no matter what I do even if I disconnect the gear cable.

Has anyone got any ideas please.
Thanks
Neil

Refer to the Parktool procedure, complete from the beginning, paying special attention to derailleur height and parallel to chainrings. http://www.parktool.com/blog/repair-help/front-derailleur-adjustments
