Bosch - Helix Race E*Spec Chainring

CR5ERA-106

LIGHTER WEIGHT. LONGER WEAR LIFE.

e*thirteen spared no expense creating the Helix R e*spec Chainring. Designed for Bosch Gen 4 e-bikes, this direct mount chainring is forged from 7075 AL for stiffness, strength and long wear life. Extensive CNC machining and our M3 tooth profile deliver an ultra lightweight upgrade chainring that offers the best cross compatible Shimano/SRAM chain retention and eye-catching technical aesthetics available. A custom outer dust cover enhances the integrated style and helps to prevent
contamination.

The Helix Race E*spec Ring is fully compatible with Shimano, SRAM, and TRP 11 and 12 speed drivetrains, and comes in many colors for coordination with e*thirteen cranks, cassettes, stems, tubeless valves and more. Available 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.
