Product details
Helix Race e*spec chainrings combine cutting-edge design and performance. This direct-mount, one-piece chainring designed for Bosch e-bikes is forged from 7075 AL, offering lightweight durability, impressive stiffness, and outstanding technical aesthetics. The custom metal dust cover enhances the style and minimizes contamination of seals and retaining rings.
The new narrow-wide M4 profile provides improved chain retention and cross-compatibility with Shimano, Sram, and TRP 11/12-speed drivetrain systems, including SRAM T-Type. It is available in a variety of colors to coordinate with e*thirteen cranks, cassettes, stems, tubeless valves, and more. The Bosch version comes in 13 mm offset (53 mm chainline) and 15 mm offset (55 mm chainline) in sizes 32T and 34T.
