Like any other aluminum frame, it's extremely stiff and allows for very quick power transfer. The CAAD 9 5 comes with the Hollowgram Si SL crankset, which with the BB30 frame makes the CAAD9 5 very light. It also features Pro-Tour geometry designed for worldwide races. The CAAD9 5 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 5 comes in Nu Team Blue with white and black accents, and Charcoal Grey with white and red accents.
