Self-extracting bolt kit for e*thirteen's 30mm-spindle Helix Race Alloy and Carbon MTB cranks, upgrading the standard M15 bolt so the crank comes off with just an Allen key.

Compatibility & fit

Fits the 30mm-spindle Helix Race Alloy and Helix Race Carbon MTB cranks — not the e*spec e-bike crank range, which uses a separate ISIS self-extractor assembly (CSS40-107).

e*thirteen's Infinite Ride Warranty covers this part for 10 years against manufacturing and material defects; it doesn't cover wear from normal use, and crash or impact damage is handled under the standard crash-replacement option rather than a free replacement. 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.
