e*thirteen Ultralight Guidering chain ring 40 Boost black

The lightest chain containers on the market

UL chainrings are the lightest 1x XC / Gravel chainrings on the market. Using the SL chainring as a platform, e.thirteen has strategically engineered the chainring so that only minimal losses in impact resistance lead to major weight savings.

UL chainrings are offset by -5 mm (Boost), for use with XCX Race cranks on Boost bikes. When installing XCX Race cranks on a bike without Boost (142 mm), please use SL chainrings.

Highlights
