When it comes to all-around performance among rim brake wheels, the HED Jet RC4 Black Clincher Wheelset has no rivals. Starting with a 21mm internal, 25mm external rim width, HED's Jet RC Black wheels feature best-in-class performance in both aerodynamics and braking technology. Hours were spent testing and refining a textured braking surface, called Turbine Braking Technology. With special machining and anodizing, the result is a clean, all-black appearance and confidence-inspiring braking performance.
Starting from our revolutionary 25mm-wide Jet Plus aluminum rim, we spent hundreds of hours testing and refining a new braking surface, called Turbine Braking Technology. With special machining and anodizing, the result is a super clean all-black appearance and outstanding brake performance. How great is it? How about 25% shorter stopping distances in dry conditions, or 70% shorter stopping distances in wet conditions. Additionally, the consistency of stopping distances has improved by nearly a factor of five. That's not a typo. HED's all-black alloy rim and carbon cap give you all of the cool factor and none of the safety compromises of rim brake carbon clinchers. No melted rims. No tire and tube failures. Only True Speed.
How good is that performance? Compared to other rim brake carbon wheels on the market, 25% shorter stopping distances in dry conditions and 70% shorter stopping distances in wet conditions. Read that again. The HED Jet RC4 Wheelset features an all-black textured alloy brake track, seamlessly matched to a hyper-aero carbon rim section, give you all-around riding performance with none of the concerns of carbon braking surfaces.

I purchased the HED Jet RC4 Black wheels last month and mounted Conti 25mm GP5000s on them. I ride a carbon Pinarello F, and the combination of the wheels and my frame feel like a dream bike that was custom made for me. After 350 miles here are my thoughts. The "feel" is the first thing I noticed. I inflated my tires to HED's very specific PSI from their website's inflation table, and it literally felt like I was riding on clouds, or for other hockey players or ice skaters, it feels like a fresh sheet of ice. The feel is immediate, and really nice: it's as if you're riding in a ultra luxury car with premium suspension. The HED wheels are on the expensive side, but you really do get what you pay for. I have picked up a couple of tenths of MPH average on my Garmin, but that could be due to any number of factors (cooler temperatures lately/fast riding groups). The rim brake stopping distance is really impressive. I haven't had to test them in wet conditions, and honestly don't plan on riding in the rain. The quality control from HED's manufaturing site is pretty solid, as there are so many Q.C. signatures on small stickers inside the rim. I am really happy with this purchase, and truly hope my experience with the Jet Black RC4s stays this way.
