Good overall comfort, slightly penalized by an uncomfortable saddle and reduced ability of the frame to filter out vibrations. More than valid the Shimano XT, equally good performance of the DT Swiss wheels. The stiffness of the frame is valid for its category and good in absolute. The relatively low weight facilitates overall performance. Uphill the bike performs well even if the light steering requires some care to maintain the correct trajectory. The handling is high and allows the bike to be very fast on winding and narrow. At speed the steering precision is sufficient , it remains light and should be concentration and decision to keep the right direction. The 29er wheels make it easier to deal with technically difficult sections, even if, at times, high maneuverability may be excessive leading to inaccuracies driving if you are not always focused. Overall, despite the 29-inch wheels, is a bike no less intuitive and easy to handle compared to other competitors. It allows better performance on slow tracks, but in exchange for a greater commitment to driving in all conditions.
