You want your performance to represent 100% of what you put in, and SRAM designed RED AXS with that goal. The heart of the AXS ecosystem is lighter, more efficient, and more capable than ever. Covering cassette ranges from 10-28t up to 10-36t, this wireless wonder has larger pulleys to decrease chain articulation and increase efficiency, and an Orbit fluid damper to keep everything in place over the rough stuff.
