HED refers to the Vanquish Pro line as their fastest wheels ever. The RC6 model nestles nicely into that category with a 61mm deep rim, balancing lightweight performance with high speed stiffness and aerodynamics. The rim is made entirely of carbon and was designed specifically to outperform the classic Jet line. The carbon layup makes it lightweight and responsive while remaining safe and reliable. Heat management was a huge focus because of carbon wheels' tendency to warp or blowout as heat rises through braking. HED best in class disc braking technology to assure a lack of heat build up as you brake. This means you can push the pace with confidence. The HED Vanquish RC6 Pro Disc Wheelset keeps you moving at the highest speeds without a weight or comfort penalty.
