Prime Threaded Bottom Bracket (Shimano)

Low Friction Bottom Bracket

Designed so that the bearings rest on the axle of the crank, these BBs provide a straight load to the bearings, which means your BB will last longer. This also allows us to make the Prime Threaded BB with tighter tolerances, so it runs smoother with less friction. This means you'll require less effort to make it up that hill or sprint for the line.

To keep our Threaded BB running smoother for longer, we use special seals that keep water out of the bearings. We use multiple smaller seals, which reduces friction and provides a better barrier against moisture and dirt. Our bearings themselves are manufactured to precision and packed with slick, waterproof grease.

All of the above combine to make the Prime Threaded Bottom Bracket the ideal choice for riders who want the best from their bike components.
