TECHNOLOGY | XDR™

The XDR drivetrain is a universal mounting system designed for cassettes containing fewer than 11 teeth. This innovative mechanism enables the creation of lighter and more versatile drivetrains, eliminating the need for new axle standards, hub conversions or investing in new cassette handling tools. The XDR interface features a length that is 1.85 mm longer than the XD standard, and has also been specifically optimized for racing hub applications. XDR drive units are compatible with all XD cassettes, provided the cassette is mounted with an additional 1.85 mm space.

TECHNOLOGY | SRAM X-Range™

SRAMX-Range™ is an innovative solution used in SRAM drive groups that provides cyclists with a wider range of gear ratios and greater flexibility in adapting gear ratios to different terrain conditions.

SRAM X-Range achieves this by increasing the gear range of the crankset and cassette. In practice, this means you can use a larger gear on the front crankset to achieve higher speeds on the flat or downhills, and a much smaller gear to tackle steep climbs. This allows cyclists to enjoy a more versatile drivetrain that is ideal for a variety of situations.

In short, SRAM's X-Range technology allows the bike's speed to better adapt to changing terrain, making the ride more comfortable and efficient, whether climbing or descending.
