The Mondraker Dualen 2011 Frame is a 4X and dirt jumping beast, here’s what the guys at Mondraker have to say about it: ‘Aluminium 6061 T6 frame designed for a 100% Four Cross and Dual Slalom use. The geometry has been developed by the World Cup competition team in order to achieve the maximum speed and also efficiency in the track. The assembling of this model offers great mobility since the upper tube and the rearstay are jointed by the same line. CNC machined drop outs offer the chance of moving the 12×135mm through shaft, so we can change chainstay length between 420 or 410mm depending on the track conditions and also the rider preferences. Tubes come with CNC machined parts to reinforce the most stressed areas without increasing the weigh, and also some details like the support forISCG chainguides turn this frame to a really professional tool’.
