UL Chainrings are the lightest 1x XC/Gravel chainrings on the market. Using the SL Chainring as the platform, we tweaked the arm design and strategically machined the chainring so that only minimal sacrifice was made in impact strength for large gains in weight reduction.

UL Chainrings are -5mm (Boost) offset, for use with XCX Race cranks on Boost bikes. 

If you're installing XCX Race Cranks onto a non-Boost (142mm) bike, please use SL Chainrings.
