Our modern world of bottom brackets is something of a labyrinth; if you can decipher the clues to find your way to the one that works for you, we commend you.

Improved seals ensure a quieter ride and reduce drag, and the smaller friction-reducing bearings that first appeared on Dura-Ace 9000 return to smooth your ride once again.
