Question

How do I tune a front derailer?

Matt Gander

Community Answer

Start with the H and L screws. The L screw stops the chain dropping off the small ring near the frame. If the chain falls off toward the frame, screw the L screw in. If the chain rubs on the derailure nearest the frame, the screw the L screw out. The H screw stops the chain falling off the biggest cog away from the frame (toward the pedal). If the chain falls off the big ring towards the pedal, screw the H screw in. If the chain rubs on the derailure on the side away from the frame (nearer the pedal, screw the H screw out. You can also adjust cable tension with the adjuster near the gear shifter.

Question

What if the rubber tire wont come off, if it is too tight?

Community Answer

Try to use a flathead screwdriver to apply leverage between the tire and the wheel. After you make a gap, push on the tire with the screwdriver to pry it off. If this does not work, you could cut the tire off, that is if you don't care about the condition of the tire.
