LIGHTER WEIGHT. LONGER WEAR LIFE.

Helix Race e*spec Chainrings merge cutting-edge design and performance. Designed for Shimano™ EP8 equipped e-bikes, this 1pc direct mount chainring is forged from 7075 AL for lightweight durability, impressive stiffness, and a standout technical aesthetic.

The new M4 narrow-wide profile delivers enhanced chain retention and cross-compatibility with Shimano, Sram, and TRP 11/12s drivetrains, including SRAM ™ T-Type™. Available in 32T and 34T sizes, it also supports dropping a chainring size to take full advantage of e*thirteen’s proprietary 9T smallest cog, wide range cassettes.
