We strongly recommend that the ceramic bearing and related products be maintained by a qualified mechanic.
Preparation
Remove the bottom bracket, bearing or jockey wheels with proper tools from the frame, hub and derailleur cage.
Clean and remove all dirt and grease outside of the products.
Maintenance Tip for Pressfit Bottom Brackets
Should creaking occur, remove the press-fit bottom bracket and reinstall it after turning it 90 degrees from its original orientation. This adjustment helps balance the load on the bearings, minimises uneven wear, and can eliminate noise while extending service life.
Maintenance
Remove the dust cover and the metal shim
