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).

SRAM X-Sync Direct Mount Boost MTB Chain RingThis SRAM X-Sync DM Chainring is specifically designed for use on "plus" size mountain bikes with their wider "Boost" type rear hubs and helps to ensure you obtain the perfect chainline for optimum performance. It's equipped with SRAM'S X-SYNC technology, which engages with the chain much quicker than standard chainrings and provides reliable chain retention over all terrains and in all conditions.SRAM 1x has been made even better with the simplicity of the new SRAM X-SYNC Direct Mount chainring. Engineered in Germany, the new Direct Mount rings bring lighter weight and greater simplicity to XX1, X01 and X1-1400 cranksets. SRAM’s Direct Mount rings give riders the perfect opportunity for a serious upgrade.Features: Material: Fully CNC'd Aluminium Recommended Group: XX1 and X01. X1 compatible Weight: 66g (28T), 68g (30T), 71g (32T), 76g (34T)Technologies:X-SYNC: SRAM 1X chainrings provide the highest level of performance and durability. Their tall square teeth edges engage the chain earlier than traditional triangle shaped teeth and their sharp and narrow tooth profile, as well as their rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1X drivetrain.Boost: With revolutionary advancements in bicycle componentry, like SRAM's XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive Trail and Enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link. This is why SRAM has developed an open standard with Boost compatible components for SRAM drivetrain, hubs and RockShox forks.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
