Compatibility & fit

Fits 68mm/73mm BSA threaded shells, for e*thirteen XCX, TRS and LG1 cranks (30mm spindle) and legacy Fifteen.G cranks. The Tune workshop carries the specialist tool and can fit this correctly as a separate service.

e*thirteen covers this bottom bracket with a 10-year warranty against manufacturing and material defects, plus a separate 1-year no-questions warranty on the bearings (crash or impact damage qualifies for a discounted replacement), per ethirteen.com. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase. For warranty support, return the product to Tune Cycles and we'll manage the claim with e*thirteen's Australian distributor.
