I was searching for an aero wheelset for my rim brake bike build, a 2009 Giant TCR Advanced SL, and HED wheels were the best option by far. When it comes to rim brake aero wheels, HED stands out as the best choice. They undergo rigorous aero testing, provide excellent customer service, and feature a black aluminum brake track that offers braking performance comparable to disc brakes. While they are slightly heavier than all-carbon wheel sets (these have a carbon faring over an aluminum rim), I believe the brake track and optimized aerodynamics compensate for this in my opinion. Additionally, the 60mm depth of the wheels is surprisingly stable in crosswinds. Initially, I was considering the slightly shallower version, but I'm glad I opted for the 60mm. One unexpected aspect is the slight noise they produce due to the carbon faring. When you encounter obstacles like rocks, you can hear a distinct pinging and echoing sound. Despite this minor inconvenience, these wheels are truly exceptional.
I've owned a pair for 5+ years. Stopped by the Hed factory and spoke to personnel for detailed information, and bought a set shortly afterward. The Hed tech recommended the RC6s vs the RC4s for overall speed, and they still are very controllable in crosswinds. My speeds increase when I ride this set of wheels. They handle great with the wider rims and corresponding wider tires (25mm usually). I love the stopping power of the rims-I use SwissStop BXP pads. People comment on the sound they make during riding, and also the turbine sound when stopping. Highly recommend.
These are excellent. With Swiss stop pads great breaking. Ride awesome. Best of all worlds. I use for training and triathlon. Would buy again above all others regardless of price
