E*Thirteen

Helix Race e*spec E-Bike Chainring - Shimano EP8

The E*Thirteen Helix Race e*spec E-Bike Chainring brings precision, durability, and quiet efficiency to your E-MTB drivetrain. Designed specifically for Shimano EP8 motor systems, this direct-mount chainring delivers a perfect blend of strength and performance for riders who demand smooth power transfer and long-lasting reliability on the trail.

Engineered with E*Thirteen’s updated M3 narrow-wide tooth profile, the Helix Race e*spec keeps your chain locked in place while reducing drivetrain noise and wear — even under the torque-heavy demands of an e-bike. The alloy outer dust cover adds an extra layer of protection, keeping grit and grime out of your setup so you can focus on the ride, not the maintenance.

With a 53mm chainline, this chainring supports dropping a ring size to take advantage of E*Thirteen’s 9-tooth cassette cog for expanded gear range without sacrificing chain retention or efficiency. Compatible with 11- and 12-speed drivetrains from both Shimano and SRAM, it’s a versatile upgrade built to ride harder and last longer.

Built for riders who push their e-bikes to the limit, the E*Thirteen Helix Race e*spec Chainring delivers the strength, silence, and precision your trail adventures deserve.
