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. Its custom metal dust cover enhances style and minimizes seal and lockring contamination.
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™. It's available in a variety of colors for coordination with e*thirteen cranks, cassettes, stems, tubeless valves and more. The Bosch version is available with 13mm offset (53mm chainlne) and 15mm offset (55mm chainline) in 32T and 34T sizes, it supports dropping a chainring size to take full advantage of e*thirteen’s proprietary 9T smallest cog, wide range cassettes.
