A race-orientated model, the Astra offers the pefect balance of rigidity and comfort. A tapered steerer and a 1.1/5” bottom headset cup improves power whilst reducing stress on the head tube and a new four leaf clover shaped tubing adds strength to the frame. It also offers better down hill and rough terrain handling. New BB shell and oversized chain stays give the rear triangle sufficient strength to keep its shape under the wattage of the world’s most powerful athletes, ensuring every ounce of power is transferred from pistons to pavement.
