The Shimano CUES FH-TC600-HM-B is a modular, sealed-bearing rear freehub built for the demands of trail, e-MTB and high-torque riding. It pairs a quick-engaging pawl ratchet with industrial cartridge bearings and a Center Lock rotor interface, giving you responsive pedalling and easy serviceability in a 12x148mm Boost package.

Highlights

• HG spline (M size) freehub body for 8-, 9-, 10- and 11-speed Shimano cassettes
• Center Lock disc rotor mount for fast, secure rotor changes
• 12mm E-Thru axle with 148mm Boost over-locknut spacing
• 32-hole drilling, suited to robust trail and e-bike wheel builds
• Quick-engaging pawl ratchet engages every 10 degrees for prompt power delivery
• Modular industrial cartridge bearings with labyrinth and contact sealing

Built for high torque

Optimised bearing positioning and a sturdy cartridge-bearing construction help the hub stand up to the extra loads of e-bikes and powerful riders, while the quick-engaging freehub keeps the drive feeling direct.

Sealed and serviceable

Rubber labyrinth and contact seals shield the bearings from water and mud, and the modular design simplifies servicing and parts replacement compared with older cup-and-cone hubs.

Compatibility & fit

Rear hub only, drilled 32H. Uses a 12mm E-Thru (thru-axle) at 148mm Boost over-locknut distance. The HG spline (M size) freehub body accepts Shimano 8/9/10/11-speed cassettes. Center Lock rotor mounting (lock ring not confirmed as included; many builds require a separate Center Lock lock ring). Check your frame requires 12x148mm Boost spacing and that your rotors use the Center Lock interface before fitting.
