Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is mainly the system approach through the integration of chainring, crank, spindle and bottom bracket that means better drivetrain performance. X-Range™ The X-Range technology was developed with the possibilities of today's dropbar bikes in mind. It is distinguished by a broad gear range with smooth, even gear changes. The combination of chainrings with 13-tooth spacing with a high bandwidth cassette, starting with a 10-tooth sprocket, ensures well thought-out, homogeneous gear jumps and always puts you in the right gear. In combination with AXS, you can make various shift settings and personalise your drivetrain to suit you.
