How do you use a barrel adjuster on a mountain bike?

Do you need barrel adjusters?

Brake and shifter barrel adjusters are necessary to fine tune caliper engagement and shift indexing. I do not recommend removing them as one day you will wish they were there. Backing a barrel adjuster all the way out will not strip the threads as there is no thread engagement therefore no damage to the threads.

A clicking noise is the most common sound your bike can make.

To identify the sound, you can slow down from pedaling and observe whether you still hear a sound.

What happens if front derailleur too high?

Derailleur Alignment & Positioning

Most front derailleurs can be adjusted for height and rotation. If the cage is set too high over the largest ring, it may not perform well. Too high a cage can cause a slow shift, and can allow the chain to shift over the largest ring.

Why is my front derailleur slipping?

For the front derailleur, you have to apply tension to the cable to get it to move to the right ("harder gear") if the cable lengthens (or slips), by even a millimeter or two, it can cause the front tuning of the gear system to get out of whack with the result being the chain dropping to the easier gear(s).

Why is my chain rubbing front derailleur?

The reason the chain rubs is because the cable is too loose. And when it's too loose, shifting onto the large chainring results in only a partial shift. With sufficient tension on the derailleur cable, the derailleur cage will move to its full outside limit and there will be clearance for the chain – and no rubbing.

Which derailleur do you adjust first?

In a nutshell, adjust the front derailleur first, then the rear. Show activity on this post. If the derailers just need minor tweaking (they are basically in adjustment but are "not quite right") then you adjust the one that is obviously wrong, check the overall adjustment again, then again adjust what needs adjusting.
