The IceToolz M582 fits the chainring lockring on Shimano's STEPS e-bike motors, so you can swap a worn chainring or change ratios without guesswork or a damaged lockring.

  • For Shimano STEPS E5000, E6100, E7000, E8000 and EP800 drive units
  • Suits the Shimano SM-CRE80 chainring and FSA spiders
  • Installs and removes the chainring
  • 1/2-inch square drive
  • Cr-Mo steel, 238g

Rigid where it counts

The lockring on an e-bike chainring is done up tight to cope with motor torque. The M582 is made from Cr-Mo steel, which keeps it rigid and impact-resistant so your effort goes into the lockring rather than flexing the tool. With the crank arm removed, fit the M582, drive it with a 1/2-inch two-way ratchet such as IceToolz's 53R4, and the chainring can come off.

Compatibility & fit

IceToolz lists the M582 for Shimano STEPS E5000, E6100, E7000, E8000 and EP800 drive units, the SM-CRE80 chainring and FSA spiders. Newer EP5, EP6 and EP801 units are listed by IceToolz for the M585. Check your drive unit model before ordering.
