The replacement alloy main bolt and self-extractor for Praxis's ETOR eCrank arms. It is made for those arms only, so check your crank before you order.

Fitting notes

An 8mm hex and a torque wrench are all you need to fit or remove the arm. Praxis specifies 40Nm for this bolt, lower than its M24 and M30 bolts, so don't carry over a torque figure from another crank. If the self-extractor ever needs replacing it is removed with a cassette lockring tool (20Nm per Praxis's crank bolt guide). Fitting is a separate workshop service, and the Tune Cycles workshop can do it for you.

Compatibility & fit

For Praxis ETOR eCranks only: Praxis's EC-Type 6 arm sets for motors with the ETOR alloy spindle. It does not fit Praxis M24 or M30 cranks, or other Praxis eCrank types, which use different bolts. If you are unsure which eCrank you have, ask us before ordering.

Praxis warrants its components to be free from defects in materials or workmanship for two years from the original purchase date, to the original owner with proof of purchase. Normal wear and tear, damage from incorrect installation or the wrong tools, crash, impact, abuse and any modification are not covered. 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 Praxis's Australian distributor.
