A replacement self-extractor bolt kit for e*thirteen's Helix Race Alloy GR crank, the gravity-focused crank built for downhill, bike park and enduro riding.

Compatibility & fit

Fits the Helix Race Alloy GR crank only — it is not interchangeable with the self-extractor kits for e*thirteen's other Helix Race or e*spec cranks, which use different spindle interfaces. The built-in self-extractor design lets the crank bolt pull the arm off the spindle without a separate puller tool. The Tune workshop can fit this during a crank service.

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.
