SRAM’s new XX1 drivetrain is packed with the latest technology in order to bring your riding to new heights. The new XX1 group has been designed to be run as a 1x11 drivetrain and will provide lightning fast shifts and flawless chain management. Each tooth on the chainring has been precisely machined to integrate with both the inner and outer links of the chain perfectly. The X-SYNC™ fits the single-ring universal spider allowing to change the chainrings without having to remove the carbon crank arm.
A full range of chainring sizes in 2-tooth steps are available, giving you the freedom to tune your gearing to your riding style. For standard use, a 32T chainring is recommended. Adjust with larger teeth for more top-end speed and less climbing gear, or go smaller for a lower climbing gear with less top end.
