My mates got a Cannondale F400. We think its about 8 years old.
The front mech is near on impossible to change up due to friction in the system. The mech itself works and moves fine. The gear changer is working fine, and the cable is lubed and clean.
So all I can think it is now is the plastic cable guide that the cable runs around under the bottom bracket. It is deeply grooved, so I assume this is creating the friction ?
What do you call that piece of plastic under the bottom bracket? Ive googled front mech gable guide and nothing is coming up...
