Technologies

X-Range™

Road bikes have become faster and more versatile than ever over the years, and cyclists are expanding their range of possibilities with a road bike. X-Range™ is an innovation for today’s cyclists. Road bike developments have been completely rethought to offer a wider and more progressive range while providing smarter shifting parameters. With X-Range™, you can be sure you’ve always chosen the best gear ratio.

X-Dome

X-Dome technology allows the creation of an incredibly lightweight, precise, and robust cassette. The open design promotes self-cleaning from mud, providing cleaner shifting and longer component life.

XDR™

The XDR™ freehub body is a universal mounting system for cassettes that include sprockets with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without the need to invent new standards for thru-axles, tools, or redesign the hub. The XDR™ is 1.85 mm longer than the XD™ and is designed for road wheels. The XDR™ is compatible with all XD™ cassettes if installed with a 1.85 mm spacer.

The XDR freehub body is not included.
