Sram XX1 Eagle DUB Boost Direct Mount 34T 1x12s crankset without BB Black 2022

Sram XX1 Eagle Boost Direct Mount Black cranckset is now made with a DUB spindle and X-Sync 2 34 teeth chainring. DUB technologie has been designed by Sram to simplify compatibilities between cranskets and bottom brackets with a unique spindle size of 28,99 mm. So it's the end of BB30 and GXP spindle, now with DUB you can use same cransket on BB30 frame and BSA 68 / 73 mm for exemple, that very difficult today. For the rest this XX1 Eagle is very lightweight and strong thanks to its new hallow carbon crankarms. The chainring has new teeth shape named X-Sync 2 to optimizes the load flange, reduces wear, improves retention, and helps clear mud better and it's compatible with 11 speed versions. But 11 speed chainrings are nor compatible with 12 speed Eagle drivetrains.
