MT ZOOM “bullet proof” jockey wheels use ceramic bearings, so last longer and are smoother than steel. The anodising holds up excellently and there’s plenty of metal to take on the most abrasive sand, mud and chain shavings.  Particularly good for winter and riding in wet and muddy/grassy conditions.  The ceramic bearings can be serviced/cleaned to prolong life & performance.

Fits most derailleurs.  If your current jockey wheel has a hole in the middle and has 11 teeth these should work. Works with 8, 9, 10, 11 etc. speed systems. Sold singularly or in pairs. 

Currently available in red and black. 

Specifications / Features

At 14g each they weigh a little more than your average plastic/alloy jockey wheels but are more durable as a result.

Set-up / Tips

Sold with a selection of shims. Pick the washer/shim that best fits your derailleur/jockey wheel bolts. Pick the width of the shim which gives enough clearance but not wide enough to get jammed between the cage & jockey wheel.Use the narrowest shims for 11 speed.

Bearings can be serviced/cleaned to prolong life & performance.  1. Remove the bearing shims & covers with a pin. 2. Blast with WD40 etc. to clean. 3. Relube / Regrease. 4. Press bearing covers back in fully.
