The Funn Fantom AM40 27.5" wheelset is the widest and most aggressive option in the Fantom range, running a 40mm external rim width designed to keep big-volume enduro tyres locked upright and planted through high-speed corners and rough terrain.

  • AL6066 welded rims — wide and tough for enduro and aggressive all-mountain use
  • 40mm external width — maximises casing support for 2.5"–3.0" tyres
  • Tubeless-ready with rim tape and valves included
  • 6-pawl 102T hubs — 3.5° engagement, near-instant power pickup
  • Boost rear spacing (12x148mm), Shimano HG freehub
  • 32H lacing, sandblasted black anodised finish

At 40mm external, the Fantom AM40 rim keeps the tyre bead firmly seated and holds the casing square for confident cornering on loose and rocky enduro terrain. AL6066 alloy is machine welded and finished with a sandblasted black anodise. Hubs use the same 6-pawl 102-tooth ratchet as the rest of the Fantom range for quick, reliable engagement.

Compatible with Shimano HG cassettes (8-speed through 11-speed). Rear axle: 12x148mm Boost. Wheel size: 27.5". Also available in SRAM XD and Shimano Micro Spline freehub options.
