Kinesis KT-620 is using the latest forming technology, SPF to form the Aero-Style frame. The water drop shape designed ISP seat tube with the hollow shape to fit the rear wheel to diminish the wind resistance.
The seat tube, down tube and chain stay are bigger where attach to B.B. set to create more strength for the B.B set. It shaped complex but it’s light. This design is easy in carbon fiber but we make it with aluminum by using our air forming technique, SPF. It passed the EN and CAE test. This does not only good looking but it also ride able.
