Halo Supadrive Freehub Body Shim

From Halo:

Replacement freehubs designed to fit Halo MT series Supadrive hubs only:

• MT Supadrive (142mm)
• MT Supadrive Boost (148mm)
• MT Supadrive DH (150mm)

These freehubs fit with Mountain Bike (MTB) standard 10/11/12 speed cassettes and are currently available to suit cassette types:

• Shimano MTB HG (MTB 10/11/12 speed with 11T smallest sprocket)
• Shimano MicroSpline (MTB 11/12 speed with 10T smallest sprocket) Supplied with end cone 
• SRAM XD (MTB 11/12 speed with 9T or 10T smallest sprocket)

The original MT series freehubs (red) used a lightweight 7075 alloy spline body with a Cr-Mo driver. The latest MT series freehubs (black) use a forged and CNC machined 1-piece Cr-Mo body, eliminating any cassette cog bite, also allowing larger bearings to be used.
