How do I reset my front derailleur?
How do I reset my front derailleur?
Begin with the chain on the smallest cog. Relax the cable tension completely using the cable barrel adjuster. Place a hand on the derailleur body to feel for any lateral motion, and select one screw to turn one full turn clockwise and then counter-clockwise. If you felt motion in the derailleur, this is the “L” screw.
Why is my bike not shifting right?
Cable tension and limit setting The most obvious and common causes for poor shifting are down to poor adjustment and the most common thing to go out of adjustment is cable tension. In the simplest of terms, sluggish upshifts can be caused by too little cable tension; while slow downshifts could be too much tension.
Should the front derailleur touch the chain?
A properly adjusted front derailleur should shift the chain between the front chainrings but will not throw the chain off the rings. The basic adjustments for the front derailleur are the height, rotation, limit screws and inner wire tension (index setting).
What to do when front derailleur does not shift?

Why does my front derailleur have multiple bends?
A bent cage can result from a crash or getting the chain jammed at the ring and being forced open by pedaling. Re-bending a cage is difficult. You often end up with multiple bends because it is difficult to isolate the first bend when attempting a fix.
Where does friction occur on a front derailleur?
An often overlook place for friction is the bottom bracket cable guides. Bare cables may pass under the shell and this contact is not easily seen. If the guides get dirty it will act to slow the cable passage.
