SRAM XX1 Eagle 12 Speed BB30 Direct Mount Crankset Boost

One by drivetrains have seen a surge in popularity as of late, and SRAM continues to lead the way towards simplified shifting and single derailleur drivetrains with its all new, 12 speed XX1 Eagle group. Not to ignore other industry trends, the SRAM XX1 Eagle 12 Speed BB30 Direct Mount Boost Crankset bumps the chainline out three millimeters to pair with your shiny new Boost equipped frameset for race worthy power transfer, impeccable chain retention, and a flash of golden flair. Building on the original X Sync chainring's renowned chain retention ability, Eagle's X Sync 2 chainring changes things up with 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 boasts 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 spinning. SRAM utilizes its Carbon Tuned technology to fashion the XX1 Eagle arms with a proprietary, hollow carbon layup that increases stiffness where it's needed and minimizes excess material for an overall reduction in weight. The direct mount chainring interface also affords the option of quickly subbing different sized rings for different shapes of terrain, giving the true all mountain racer the start line flexibility to adapt to a given course.
