The Sirrus X is the off-road brother of the Sirrus. If you like rougher terrain and often take a diversion through nature, the Sirrus X is more suited to that than the 'street version' of the Sirrus. The frame is built a bit wider to fit even wider tyres for more comfort and off-road use.

If you really want to sport it and want to keep the weight of the bike to a minimum, choose the non-equipped version. And if you really want the lightest bike possible, opt for the carbon versions.

From the Sirrus X 4.0 onwards, these bikes come standard with the Future Shox system in the front fork which provides extra suspension and comfort. It is available with or without mudguards and lighting (EQ).
