The BB30 is roundly slated on the various forums I’ve been searching. Tried loading it with grease then cleaning it all out and using loctite instead. All other potential sources of noise eliminated. All chain ring bolts correctly torqued…. No missing spacers, preload adjusted correctly (but tried it in all positions)….. Nothing…… Arghh! A stronger loctite may be worth a shot. Reply: Our C-Bear bottom brackets can be installed without Loctite and do not require any adapters or spacers (therefore eliminating noises) . Click here to ask a Question about this product.
