Replace or upgrade the freehub body on a Spank Hex, Hex Gravel, Oozy or Spike hub without replacing the whole wheel — the swap drops straight onto the hub's existing driver spline.

Highlights

  • Alloy Bite Block freehub bodies resist cassette damage without steel's weight penalty
  • Steel freehub bodies available for extra durability on high-torque and e-MTB use
  • Shimano HG, Shimano HG Road (HGR), Shimano Microspline, SRAM XD and SRAM XDR driver standards
  • Fits Spank Hex Drive hub spacings (148 Boost, 150/157 and 142/135)
  • Some drivers are supplied with a spacer ring — see options below

Driver and material options

Spank's Hex freehub bodies are a swap-in design: remove the old freehub and axle end cap, drop in the replacement, and the hub is back in service in under a minute. Alloy bodies use Spank's Bite Block design to resist cassette damage; steel bodies trade a little weight for extra durability.

Compatibility & fit

Fit the freehub body that matches your hub's original driver standard and your cassette (Shimano HG, HG Road, Microspline; SRAM XD, XDR). Our workshop can fit a replacement or upgraded freehub body and check hub bearings while it's apart.
