Built for racing, not everyday abuse

e*thirteen pared back the shell diameter and CNC-machined the flanges to hit a genuine XC race weight, with the flange angles and chamfered spoke holes calculated to reduce stress on lightweight J-bend spokes.

Compatibility & fit

Rear hub only — pair with the matching Ultralight XCX Race front hub. The Microspline freehub fits Shimano 12-speed MTB cassettes only, not HG, XD or XDR. Fits 148×12mm Boost frames with a 6-bolt rotor.

e*thirteen's Infinite Ride Warranty covers this hub's bearings for life (the Free Speed Hub Bearing warranty) and the rest of the hub for 10 years against manufacturing and material defects. Normal wear, crashes, modifications and commercial use are excluded. For warranty support, return the product to Tune Cycles and we'll manage the claim with e*thirteen's Australian distributor. This is in addition to your rights under the Australian Consumer Law — keep your proof of purchase.
