A Microspline freehub rebuild kit covering e*thirteen's TRS, LG1 EN, MY21/22 e*spec Base/Plus, Sylvan, Optimus and Grappler hubs, with 3-pawl/6-degree engagement.

Compatibility & fit

e*thirteen's own fitment groups TRS and LG1 series hubs together with its current e*spec Plus hubs for this driver, which matches this kit's wider fitment list. It is not interchangeable with the e*spec Race (V40) or XCX-specific Microspline kits, which use different generations of driver.

Covered by e*thirteen's 10-year warranty against manufacturing defects under the Infinite Ride Warranty Policy. Normal wear, crash damage, modification 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, so keep your proof of purchase.
