Technologies

X-Range™

Road bikes have become faster and more versatile than ever over the years, and cyclists are expanding the 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.

XDR™

The XDR™ body is a universal mounting system for cassettes that include gears with fewer than 11 teeth. It allows for the lightest and most 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.

Full Pin™

Full Pin technology allows the 12 steel sprockets of the cassette to be joined together using 136 high-strength stainless steel pins. This results in an extremely lightweight and durable cassette equipped with the incredible gear range that only Sram can offer. The open design similar to X-Dome cassettes helps reduce mud buildup while ensuring consistent shifting and long component life.
