With SRAM's determined push to send front derailleurs the way of the dodo, it was only a matter of time until the limited gearing of 11-speed became old news. Swooping in to set the curve on one-by gearing options, the SRAM XX1 Eagle 12-Speed BB30 Direct Mount Crankset drives forward with updated designs and a flash of golden bling.
Building on the original X-Sync chainring's renowned chain retention ability, Eagle's X-Sync 2 chainring ups the ante with claims of even better chain control. As with the original, each tooth is CNC-machined to support the chain's inner- and outer-links and provide a variable thickness from tooth-to-tooth, so the chain and chainring essentially lock together as you pedal. Where each tooth took on a boxy profile in the original version, Eagle's chainring boasts aggressively profiled teeth reminiscent of those found in the ocean's fiercest predator, a design that grabs the chain when it needs to and fends of mud for smooth, friction-free function.
SRAM utilizes its Carbon Tuned technology to build the XX1 Eagle arms with a carbon layup that reduces weight while increasing stiffness and durability. Their hollow construction results in a light, responsive platform that lets you dance on the pedals and power down the trail. The direct-mount chainring interface also affords the option of quickly subbing different sizes of rings for different shapes of terrain, giving the true all-mountain racer a bit of start-line flexibility to adapt to a given course.
