Bring your Shimano STEPS e-MTB or e-bike back to crisp, reliable shifting with this genuine 32-tooth replacement chainring. The lower 32T gearing gives you an easier climbing range and more usable cadence on steep, loaded rides, while Shimano's purpose-built tooth profile keeps the chain locked in place over rough ground.

Highlights

  • Genuine Shimano STEPS replacement chainring, 32 teeth
  • Lower gearing for easier climbing and better control at low speed
  • Dynamic Chain Engagement+ tooth profile resists chain drop on rough terrain
  • Steel construction built for the high torque of a mid-drive motor
  • 50 mm chainline matched to the STEPS E8000 drive unit

Why a 32T ring

Dropping to a 32T front ring lightens your hardest gears, which is ideal for technical climbs, fully loaded touring or simply spinning a smoother cadence with assist. It is a popular swap for riders who want more bottom-end range from the same drivetrain.

Built for e-bike torque

Mid-drive motors put far more load through the chainring than a standard crank. This ring uses steel teeth and Shimano's Dynamic Chain Engagement+ profile, designed to hold the chain securely and reduce drops when the trail gets rough.

Compatibility & fit

This chainring is the genuine Shimano service part for the STEPS E8000 family. It fits the FC-E8000, FC-E8050 and FC-M8050 cranksets (the version without a chain guard) and the CR-EM800 crank. It uses the 4-arm, 104 mm BCD spider mount with a 50 mm chainline and is intended for Shimano's 1x10/1x11-speed e-bike drivetrains. Confirm your existing crank model and chainline before ordering; if you are unsure, contact us and we'll help you match the correct part.

This genuine Shimano part is covered by Shimano's standard warranty against defects in materials and workmanship. The warranty does not cover normal wear (chainring teeth are a wearing item), damage from crashes, improper installation, or use outside the product's intended application.

For warranty support, return the item to Tune Cycles and we'll manage the claim for you.

This warranty is in addition to your rights under the Australian Consumer Law. Our goods come with guarantees that cannot be excluded under the Australian Consumer Law.
