TECHNOLOGIES

X-RANGE ? was developed with the possibilities of today's dropbar bikes in mind. It is distinguished by a wide 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.

X-SYNC ? The tooth profile of the chainring increases the chain tension, efficiency and when pedaling and supports the chain guide. As well as friction and contamination are reduced and thus the service life increased.
