SRAM has developed X-Range gearing: 3 new chainring sets and 3 new cassettes that cover all riders' needs, from WorldTour to endurance and gravel. SRAM Red eTap AXS is now 12-speed with wider gear ranges (up to 10-33, or 330%) and smoother gear progression. That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. And when a front shift is executed, the smaller jump is smoother and allows you to get to the right cadence with fewer compensation shifts in the rear. SRAM's Orbit technology limits chain bounce by controlling the chain's downward movement when riding over bumps. Orbit is a new, patented design that consists of a silicone fluid damper with a one-way valve that controls the rear derailleur cage's counter-clockwise rotation. To gain a wider gear range with smaller gearing steps, the chain has to get narrower. With the new Flattop chain, SRAM added material on the flat side of the chain plates to strengthen every link. The Hard Chrome surface treatment on the pins, inner plates, and rollers also extends the life of the chain, lasting 36% longer than 12-speed chains, and keeps it shifting precisely over the long haul. AXS is SRAM's new electronic integration platform that connects electronic bicycle components and software. The SRAM AXS App allows riders to see battery status, change components behavior, personalize controls, get maintenance reminders, and update firmware to keep the wireless drivetrain running smoothly.
