SRAM X01 Eagle 12 Speed BB30 Direct Mount Crankset Boost

With SRAM's new one by, 12 speed Eagle drivetrains sending front derailleurs and 11 speed cassettes packing, it might just be time to upgrade your ride. The SRAM X01 Eagle 12 Speed BB30 Direct Mount Boost Crankset enjoys much of the same technology found in the flagship XX1 Eagle group. It does feature less obviously blingy graphics and leaves a few extra dollars in the bank for delicious post ride brews, though. This version bumps the chainline out three millimeters to pair with your Boost equipped frameset for race worthy power transfer and impeccable chain retention. Eagle's X Sync 2 chainring builds on the original X Sync chainring's renowned chain retention ability with a few changes that come 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 catnip infused cat digging its claws into a brand new screen door before letting it glide seamlessly back to the cassette for smooth, friction free spinning. SRAM utilizes its Carbon Tuned technology to fashion the X01 Eagle arms with a proprietary carbon layup that increases stiffness where it's needed and minimizing excess material for an overall reduction in weight. In contrast to its top tier XX1 Eagle cousin's hollow core construction, the X01 Eagle crank arms feature a foam core that adds a handful of grams to keep costs down without impacting responsiveness. The direct mount chainring interface also affords the option of quickly subbing different rings for different shapes of terrain, allowing flexibility to adapt to the day's planned route.
