Featuring a tough aluminium build with an ultralight design, minimal aesthetics, and updated M3 narrow-wide tooth profile, the e.thirteen UL Guidering Direct Mount Chainring is well-equipped for cross country (XC) racing and gravel riding.
Classed by the brand as the lightest 1x XC/Gravel chainring on the market, this model features an updated M3 narrow-wide tooth profile that eliminates chain noise and decreases overall system wear. Its robust 7050 aluminium construction also makes it more than capable of withstanding all the knocks and bumps associated with racing and exploring across mixed terrain conditions. Using the SL Chainring as the platform, e.thirteen 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 (available separately).
