Deore XT crank arms for Shimano STEPS e-MTBs

The FC-M8150 is the Deore XT crank arm set for Shimano STEPS e-MTB drive units. Hollow forged arms keep the weight down and the stiffness up, and the set fits the drive-unit spindle directly, so there is no bottom bracket to buy.

Choose your length

Shorter arms give more ground clearance on a mid-drive e-MTB; choose 160, 165 or 170 mm. Sold without a chainring — add the direct-mount ring your drive unit takes.

Compatibility

For Shimano STEPS e-MTB drive units. Not for conventional HOLLOWTECH II bottom brackets.

Shimano offers a limited warranty covering defects in materials and workmanship. Wear, incorrect installation and crash damage are not covered. For warranty support, return the item to Tune Cycles with your proof of purchase.
