Like any other aluminum frame, it's extremely stiff and allows for very quick power transfer. The CAAD9 4 is very close to having that elusive balance that makes a race bike both expendable and valuable at the same time. With the CAAD9 4 sprinting, climbing, and corning is very solid, and the Premium carbon fork dampens the harshness of the road beneath you. The CAAD 9 4 comes with the Hollowgram Si SL crankset, which with the BB30 frame makes the CAAD9 4 very light. It also features Pro-Tour geometry designed for worldwide races. The CAAD9 4 has a top tube with a larger diameter at the head tube, and a down tube and seat tube that enlarged as they reached the bottom bracket. It is solid, well balanced and predictable. The CAAD9 4 comes in jet black (matte) and race red with white and black accents.
