Gravel Clutch Kit for Jab Derailleur

Adjust or rebuild your Jab Gravel clutch. The Jab clutch is adjustable and serviceable with common tools. It is best to do this in a workshop (not on the trail) to prevent grit from getting into the clutch. Clean it, re-grease it, adjust it with shims, and you are good to go!

To adjust your clutch, you can add or remove shims from the stack (which has multiple shims stacked up). This adds or removes preload from the conical disc springs that apply friction to the cage.

The complete gravel clutch kit includes all the parts you might need, but if you only need to adjust your clutch, you can also get the 0.1mm adjustment shims.
