LIGHTER WEIGHT. LONGER WEAR LIFE.
Helix Race e*spec Chainrings merge cutting-edge design and performance. Designed for Bosch® equipped e-bikes, this 1pc direct mount chainring is forged from 7075 AL for lightweight durability, impressive stiffness, and a standout technical aesthetic.
With a long-wearing tooth profile and refined aesthetic, the integrated look, when paired with Helix Race Alloy e*spec cranks, is the ultimate upgrade to your ebike.
The new M4 narrow-wide profile delivers enhanced chain retention and cross-compatibility with Shimano®, Sram®, and TRP® 11/12s drivetrain, including SRAM® T-Type®. It's available in a variety of colors for coordination with e*thirteen cranks, cassettes, stems, tubeless valves, and more.
