Replacement crank fixing bolt and self-extractor kit for e*thirteen XCX Race cranks, so you can pull the crank arm with just a hex key instead of a separate crank puller.

Kit includes the self-extracting bolt, washer and extractor insert for the crank's Gen 4 interface.

Compatibility & fit

Fits XCX Race cranks only – e*thirteen sells separate self-extractor kits for its other crank families (Helix Race Carbon, e*spec e-MTB cranks and more), so check which crank you have before ordering. Torque to e*thirteen's 20Nm spec for self-extractor caps. The Tune workshop can fit this as part of a crank service.

e*thirteen's Infinite Ride Warranty covers this part for 10 years against manufacturing and material defects; normal wear on wear parts such as pawls, springs and cogs isn't covered. 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.
