Token's Ninja bottom bracket is built to end creaking bottom brackets, extend bearing life and stiffen up the crank-to-frame connection on BB386/BB392 frames running SRAM DUB cranksets.

Highlights

  • Fusion technology: an alloy shell wrapped in a machined plastic-and-fibre composite for a snug, creak-free fit in the frame
  • Extended alloy shell locks the drive and non-drive sides together for a stiffer bottom bracket junction
  • TBT ceramic ball bearings, supported on a solid alloy platform for a longer service life
  • Thread-together installation, not press-fit

How it works

Token houses the bearings in an alloy shell wrapped in plastic and fibre composite cups. This combination gives the bearings a solid, precisely machined platform to sit on, while the composite exterior fits snugly against the frame bore to stop the movement that causes creaking. The two shell halves thread together, locking frame, cranks and bottom bracket into one stiffer unit.

Compatibility & fit

Fits BB386 and BB392 frame shells (46mm bore, 86.5mm/92mm width) and SRAM DUB cranksets (28.99mm spindle). TBT bearings measure 40 x 29 x H6.8mm; the set weighs approximately 109g.

Fitting

Our workshop can fit and check bottom brackets as part of a service — ask in-store or when you book online.

Token bottom brackets carry a 2-year warranty against defects in materials or workmanship from the original date of purchase, covering the original purchaser only.
