Description
The Helix Race e*spec chainrings combine cutting-edge design with top performance. Designed as an upgrade for the most popular e-bike motor systems, this one-piece direct-mount chainring is forged and milled from 7075 aluminium. They are characterised by their light weight, durability, impressive stiffness and outstanding technical aesthetics.
With a low-wear tooth profile and a sophisticated look, the integrated design—combined with the Helix Race Alloy e*spec cranksets—is the ultimate upgrade for your e-bike.
The M4 Narrow-Wide profile ensures improved chain retention and cross-compatibility with Shimano®, SRAM® and TRP® drivetrains from the 11/12-speed series, including SRAM® T-Type®. It is available in a range of Specialized® colours to match e*thirteen cranks, cassettes, stems, tubeless valves and much more.
