The Cube Attain GTC is built around an excellent carbon fibre frame. The Carbon Comfort Frame was developed by Cube from the ground up, & this in turn has created class-leading comfort, performance & low weight. The rear end's slim seat stays are designed so that they reduce the impact of shocks from the road surface to the rider. This advantage is seen most on longer rides, increasing comfort & reducing the symptoms of fatigue & tension, allowing you to ride further & faster without some of the lasting soreness the next day.
