Our DNA comes from DH racing, there’s no denying it and we’re proud of it. DH is the Formula 1 of mountain biking. It’s where prototypes are put through the wringer, hammered by the tracks and the riders.
That’s why at Mondraker we have a top-level international team: the Mondraker Factiry Racing, which includes world-class riders such as Dakotah Norton and Ronan Dunne. Our DH bikes will continue to be available as carbon or aluminium framed versions, depending on rider preference.
