Shell width

This bracket is sized specifically for 100mm fat bike shells — it is not the same part as e*thirteen's standard 68/73/83mm BSA bottom brackets.

Compatibility & fit

Fits 100mm-wide BSA threaded fat bike shells, for e*thirteen 30mm-spindle cranks only. The Tune workshop can fit this as part of a fat bike drivetrain 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.
