Product Description
One-by drivetrains appear to be the way of the future, and SRAM is leading the way with its revolutionary one-by 12-speed Eagle drivetrains. Featuring an upgraded tooth shape and hollow construction, the SRAM XX1 Eagle 12-Speed GXP Direct Mount Boost Crankset bumps the chainline out three millimeters to pair with your shiny new Boost-equipped frameset for impeccable chain control, efficient power transfer, and a gleam of golden flair. Eagle's X-Sync 2 chainring builds on the OG X-Sync chainring's renowned chain retention ability, with a few changes and claims of even better chain control. As with the original, each tooth is CNC-machined to support the chain's inner- and outer-link widths by providing a variable thickness from tooth to tooth, so the chain and chainring essentially lock together and push away mud with ease. Where the original X-Sync teeth took on a boxy shape, Eagle's chainring features aggressively profiled teeth that hold the chain like a wild-eyed kitten clinging to a catnip-soaked mouse toy before letting it glide seamlessly back to the cassette for smooth, friction-free turns. SRAM fashions the XX1 Eagle crank arms using its Carbon Tuned technology, which utilizes a proprietary carbon layup that increases stiffness where it's needed and minimizes unnecessary material for an overall reduction in weight. Their hollow construction results in a lightweight and responsive platform that'll see you dancing on the pedals as you pour watts into the trail. The direct-mount chainring interface also affords the option of quickly swapping ring sizes to adapt to the day's terrain shape, giving the true all-mountain racer the start-line flexibility to adapt to the day's course.
