Bought this bearings mid Oct 2024, less than 500 miles they started to make noise and a few days ago beginning of March 2025 and they are toasted …not recommended at all …So they last me about 5 months or less …I’m not happy with this product at all 👎🏼👎🏼👎🏼

Fit and installed fine like you’re supposed to. Immediately out on the trail the following day, creak creak creak. Not good. Classic BB30PF30 creak due to the bearings not being machined properly to the correct tolerance.Read the other reviews about how “bad” they are and thought indifferent, should have listened to them.

Great bearings have about 4000 miles on them still rolling smoothly installing it was easy just be sure you are putting everything back correctly very important. For the price you could be putting fresh bearings every 2 years.

Update - less than 500 miles and the bearings are toast. Heard popping while pedaling and bike shop that installed these pointed out the racket the bearings are making now.Ultimately you get what you pay for. $30 bearings get you $30 worth of bearings.Seems pretty smooth, still breaking in as I've not had a lot of time to ride that bike specifically.
