Flexy in every way, not only in the special shape of the top tube featuring P.A.T. technology absorbing vibrations from the ground. The F-GR02 frame is also designed to house two different types of wheel, depending on the route you want to travel. Assemble the 700C carbon wheels with slick tyres and you will be astounded by its speed and lightness on the road. With 650B wheels and lugged tyres, single tracks through the forest are never a problem, in any weather.
