It's over. You're caked in mud, barely able to recognize your own selfie, the bike's weeping beside you with a seized drivetrain, and your ride mates are wondering when the ride will get going again. The last thing you want to have happen is to miss out on some good fun because your drivetrain couldn't handle a bit of nature. In comes the SRAM XX1 Eagle 12-Speed BB30 Direct Mount Crankset, whose teeth act like dental floss for your chain.Improving on the original X-Sync chainring, the X-Sync 2 chainring is machined with variable thickness from tooth-to-tooth for an advanced level of connection between chain and chainring. Highly crafted teeth move beyond the traditional boxy profile, reducing friction and pushing the mud from the chain and back onto the trail for some other less fortunate rider to find later.The crankarms feature a carbon layup and hollow construction, which both reduce weight and increase stiffness and durability. Multiple sizes of chainring can also be utilized with the direct-mount configuration, suiting a wide-range of terrain and event characteristics.
