Product details
Our hubs come standard with Enduro high-carbon chromium steel bearings which have the best price/performance ratio, but if you are seeking the absolute pinnacle of bearing performance, we also offer Enduro XD15's which features ceramic balls rotating in aerospace developed, nitrogen-infused, super-stainless-steel bearing races and come with a limited lifetime warranty.
Consult the Specs tab for specific hub model bearing info, which is also available on the respective hub model pages.
