Make that daily ride from your front door a little spicier with some dirt. The 440% range of the XPLR XG-1251 cassette provides smooth gear progression when you’re sweating up gravel climbs, and tight jumps on the high end for when it’s time to drill it on asphalt. Shift features on each cog are optimized for electronic shifting, so you’ll get fast, smooth, and precise shifts every time.

Technology

MINI CLUSTER

THE MINI CLUSTER hybrid cassette construction combines four small cogs that are CNC-machined out of a single block of billet steel with an additional eight cogs that are individually pinned together. The result: a cassette that's light, durable, and equipped with a rear range that's a perfect fit for any ride.

XDR

The XDR driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools, or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR cassettes are used when the cassette is installed with a 1.85mm spacer.

X-Range

Road bikes are faster and more capable than ever before, and riders are expanding what's possible with drop bar bikes. X-Range is geared for today's road bike riding. We completely reimagined road gearing, or wider range, more useful, and smoother gear progression, as well as smart shift settings, enabled by AXS. With X-Range, you're always in the right gear.
