Description
The Promax EX-2 English bottom bracket features forged and CNC machined aluminum cups, dual-lip labyrinth low-friction seals, and custom sealed bearings.

Features
  • For 30mm crank spindles. Built for 30mm diameter spindles such as RaceFace and Easton CINCH, so check what your cranks run before ordering.
  • English threaded, 68 or 73mm. It threads into a 1.37 inch English shell in either 68mm or 73mm width, which covers most frames.
  • Dual-lip labyrinth seals. Low friction seals keep the elements out without dragging on your pedal efficiency.
  • Forged and CNC machined cups. The aluminium cups are forged then machined, so they come out strong, stiff and light.
  • Custom sealed bearings. The bearings are made for this bottom bracket, running smooth and lasting through the season, all for 105g.
