Core e*spec Chainguides offer a lightweight, durable chain retention solution for Bosch® CX Gen4, Gen5, and Shimano® EP8 motor systems, with 55mm chainlines.
Core e*spec Guides are designed to provide the long-lasting performance of an alloy backplate guide, with a wider 55mm chainline for modern Boost and Super Boost e-bikes.
