TORAY T800 Carbon Fiber: We use high quality Japanese Carbon fiber for frame, wheelset, fork, handle bar and seat post. This not only provides you with a good damping system and an ultra-light road bike at 7.8 kg (17.2lb) but guarantees power-efficient riding.
Advanced Rear Triangle & Tapered Head Design: The design of a short rear triangle makes the frame more stiff and easy to control which can also enhance the instant explosive force while riding. The 1-1/8″-1/2″ tapered headtube strengthens the torsion rigidity and give riders a better handling. In this way, it can also reduces 11% cross section area which improves performance, reduces wind resistance and enhances aerodynamic efficiency.
