Helix Race e*spec Chainrings merge cutting-edge design and performance. Designed for Bosch SX and Gen 4 CX 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.
