The heart of SRAM’s XX1 1×11 speed drivetrain! X-Sync: A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entire chainring, perfectly mirroring the chain’s inner and outer links for maximum control. Six available chainrings (28-30-32-34-36-38) allow the rider to tune their gearing to match their wheel size, riding style, and the terrain Carbon arms with forged aluminum spider New spider design allows for easier ring changes Does not include BB assembly Black Average weight: 650 grams including bottom bracket.

Force goes 11 speed! Carbon arms mated to an alloy spider maximize stiffness while minimizing weight Hidden bolt pattern leverages the characteristics of carbon fiber while presenting a sleek appearance 11 speed X-Glide R chainrings are optimized for use with the Yaw front derailleur, allowing them to deliver crisp, lightning quick shifts every time Does not include BB assembly Black Average weight: 820 grams/including GXP, 755 grams/including BB30.
