XCX Ultralight Guidering

E*thirteen developed the XCX Race Carbon Crank to be one of the lightest production cranksets on the market, which means they needed to make a suitable chainring to match. The XCX Ultralight Guidering is the result of this endeavor, designed to match perfectly with the XCX Race Carbon Crank. Despite the low weight, e*thirteen spent months and months of testing to ensure you aren't losing out on strength and wear life. The XCX Ultralight Guidering uses a narrow-wide tooth profile for optimal chain retention, and is compatible with 10, 11, and 12-speed drivetrains. This particular version is designed for mountain bikes with Boost hub spacing, and is only compatible with e*thirteen's direct-mount Quick Connect mounting interface.
