Born to surpass the demands of the world’s top XC athletes, the Fourstroke 01 delivers the ultimate performance on the most demanding courses. A purpose-designed race machine, every element of its structure is crafted to optimize speed, save seconds, and keep riders ahead of the pack.

Race Application Dropper

The functionality of a dropper post and the visual appeal of an integrated design combined in a featherweight solution – that’s RAD. With an overall weight of only 345g, RAD shaves off more than 100g over a conventional dropper post design while delivering maximum descending and uphill performance.

Details Make the Difference
