Designed for use with all cranksets from e*thirteen components, the SL Guidering Direct Mount makes it easy to revamp your drivetrain or build a new one. It's compatible with anywhere from 8 to 12-speed drivetrains, so as long as you're following industry trends and building a 1x you should be good to go. It's made with EXA aluminum which provides lightweight durability, and is machined for a consistent shape--designed to improve chain retention. e*thirteen finishes it off with a long-wearing coating that extends the lifespan of the guidering, keeping you from starting this process over for longer.
