The Funn Fantom Rear Hub in 12x148mm Boost is engineered for trail and all-mountain riders who run SRAM drivetrains and demand immediate engagement on every technical move.

  • 6-pawl 102-tooth ratchet — 3.5° engagement angle
  • 12x148mm Boost axle standard for increased frame stiffness and tyre clearance
  • SRAM XD freehub for 10- to 12-speed SRAM cassettes including Eagle
  • 32-hole drilling for versatile wheel builds
  • AL6061 alloy shell, 6-bolt disc mount, black finish

Six pawls engage simultaneously on a 102-tooth ring, giving 3.5° of engagement — near-instant bite when power is applied. The AL6061 alloy shell is precision-machined to close tolerances for smooth, long-lasting bearing preload.

The SRAM XD freehub body is compatible with 10-speed, 11-speed and 12-speed SRAM cassettes including the full Eagle range. Suits any Boost frame with 12mm thru-axle rear spacing.
