E-THIRTEEN E13 UL Direct Mount Boost 5 mm Offset Chainring
Unleash the ultimate competitive advantage with the E-THIRTEEN UL Direct Mount Chainring, meticulously engineered for riders who demand the absolute lightest and highest-performing components. As the pinnacle of lightweight design, the UL chainrings stand as the lightest XC and Gravel options available on the market, making them the definitive choice for racers and performance enthusiasts chasing marginal gains and a significant reduction in overall bike weight.
Building upon the proven and successful platform of the SL model, our engineers have taken performance to the next level. Through strategic and advanced machining processes, we have meticulously refined the design to remove every unnecessary gram of material. This optimization achieves a remarkable weight reduction without compromising the structural integrity and strength you expect from e*thirteen. The result is a no-compromise chainring that delivers podium-worthy stiffness and durability in an astonishingly light package, perfect for aggressive XC and demanding Gravel riding.
This specific UL model features a -5 mm offset, making it the perfect solution for achieving an optimal chainline on bikes with Boost (148mm) rear hub spacing when paired with e*thirteen´s XCX Race model cranks. This precise alignment is critical for crisp shifting, drivetrain efficiency, and reduced wear. For riders using XCX Race cranks on a non-Boost (142mm) frame, the e*thirteen SL series chainrings are recommended to ensure flawless performance.
At the heart of the UL chainring´s superior performance is the updated M3 narrow-wide tooth profiling. This advanced tooth design is engineered to perfection, creating a seamless interface with your chain. It virtually eliminates distracting chain noise for a blissfully silent ride, allowing you to focus purely on the trail ahead. Furthermore, this innovative design significantly decreases overall system wear, extending the life of your entire drivetrain while providing exceptional chain retention over the roughest terrain. The QuickConnect™ direct mount interface ensures a secure, solid fit and allows for quick and easy chainring swaps.
UL dishes are the lightest XC and Gravel dishes on the market.
Using the SL model as a platform, we strategically modify its machining and design to achieve the same strength with a great weight reduction.
UL plates have a displacement of -5 mm (Boost), for use with XCX Race model cranks on Boost bikes.
If you use XCX Race cranks on a bike other than Boost (142 mm), use the SL plates.
Updated M3 tooth profiling eliminates chain noise and decreases overall system wear.
