HED refers to the Vanquish Pro line as their fastest wheels ever. The RC8 model nestles nicely into that category with a 84mm deep rim, offering incredible aerodynamics that does not sacrifice weight or comfort. 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 buildup as you brake. This means you can push the pace with confidence. The HED Vanquish RC8 Pro Disc Wheelset gives you the aero advantage you need to hit your highest speeds on the road.
