Helix R e*spec Chainrings merge cutting-edge design and performance. Designed as an upgrade for the most popular e-bike motor systems, this 1-piece direct mount chainring is forged and machined from 7075 AL. Boasting lightweight, durability, impressive stiffness, and a standout technical aesthetic, they're available for Bosch CX Gen4/Gen5, Bosch SX, TQ HPR50, Fazua Ride 60, Shimano EP8, DJI Avinox, as well as Specialized SL1.1 and 2.1/2.2 motors.
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 e-bike.
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 Specialized® colors for coordination with e*thirteen cranks, cassettes, stems, tubeless valves, and more.

- 13mm for 53mm chainline on CX Gen4/SX and 55mm chainline on CX Gen5 bikes
- 15mm offset for 55mm chainline on CX Gen4/SX, and 57mm chainline on CX Gen5
