With the combination of wind tunnel tuned aerodynamics, light weight, stiffness, and unmatched range of adjustability, we guarantee that you will not fit better or go faster on another bar. Our Corsair full aero bar is our lightest and stiffest offering to date (585g including brake levers). New for 2011 we offer the Corsair base bar compatible with Shimano's Di2 shift/brake levers. This also means it is well adapted to track use or brake levers of your choice. The base bar is compliant with the UCI's 3:1 aspect ratio rule.
