BB30 to Shimano Bottom Bracket + ABEC-3 Bearings

The Wheels Manufacturing BB30 to Shimano Bottom Bracket is what we install when we’ve got a smooth Shimano 24mm crank to affix to a BB30 bottom bracket. This master-crafted bottom-bracket uses high-quality ABEC-3 bearings, that with proper care, last a lifetime on our bikes. Thankfully this is a ‘thread together’ bottom bracket, meaning creaking bearings of the past are a non-issue once this is installed.
