Compatibility, Size and Fit
This bearing set is meant for bicycle headset replacement and is listed for mountain bikes, MTB bikes, ordinary bicycles, lowrider bikes, and stretch bicycles. The most important check is still the exact headset and bearing size on the bike you own.
If the headset size or bearing dimensions do not match, choose a different replacement part rather than relying on visual similarity.
