An eccentric bottom bracket that lets a BB30 or PF30 frame run single-speed by adjusting chain tension at the bottom bracket instead of a derailleur.

Highlights

  • Converts BB30 or PF30 frames to single-speed
  • Enduro ABEC-5 angular contact sealed bearings with double lip seals
  • Machined aluminium construction
  • Fully serviceable

Important fitment note

Wheels Manufacturing states this eccentric bottom bracket will not work in frames without removable c-clips in the shell — if the shell has a moulded step that the bearings press against, it will not fully seat.
