T47 threaded BB cups for T47 frames and 24mm diameter cranksets. The cups have internal bearings and are typically used in BB shells wider than 73mm. The machined aluminum cups screw directly into a T47 BB shell. The bearings are easy to maintain or replace. T47 BB cups are similar to standard BSA threaded cups in that the drive side has left-hand threads and the non-drive side has right-hand threads. When installing in steel or aluminum BB shells, use a high-quality lubricant and an anti-seize compound compatible with titanium BB shells.
