Angular Contact (A/C) ABEC-5 Bottom Bracket


For the ultimate bottom bracket bearings, and for many hubs, these are the best bearings available for speed, balance, and longevity. Because they utilize a large surface area design, the load from all the balls is shared equally at all times, spinning faster than any radial bearing where only 30% of the balls may be taking the load. A patented Enduro Bearings design, they may be serviced just as any other bearing with no special tools needed. Perfect for disc brake wheels where you need to remove all wheel play.  Just remember, the RED color seal side is the loading side; don’t BLACK out!
