We couldn't find an aerobar under 500 that combined the full adjustability of a semi-integrated design with the performance benefits of carbon fiber construction. so we made one. The Williams Thrust CCS has all the features of a top end carbon aerobar at a price that beats most of its alloy competitors. A carbon fiber aerodynamic wing bar is paired with under mounted carbon racing-bend extensions for a low aerodynamic profile. The bars are completed with fully adjustable carbon armrests that offer four different clamping widths and 35Degree of longitudinal shift. These different armrest positions, the ability to use this bar with any 31.8 stem and 130mm of fore/aft adjustment in the extensions means you'll be able to make the tweaks you need to achieve your most aerodynamic position. Internal cable routing keeps your cockpit sleek and aero and the mounting ends feature alloy inserts so you can use TT shifters and brake levers with total confidence in the bar's durability. Because the Thrust is designed as a racing bar and not just a show pieces it meets the UCI 3:1 requirement, so you can use them in any competition. Whether you're charging to the end of a 5k prologue or a 112 mile bike leg the Thrust CCS is the bar your want supporting you along the way.
