Gray wheels are handmade from high modulus carbon. The rims are designed for maximum aerodynamics and minimum weight, while retaining incredible structural strength. In fact, structural strength is the area our engineers have made our primary focus. This has allowed us to produce an extremely solid, strong and stiff rim that can handle a rider up to 240 lbs, while still maintaining extremely light weight.
We offer 8 specific wheel models. Each model is designed to optimize specific riding conditions. The 40mm Full Carbon Clincher is designed as a great training, criterium, and climbing wheel. The 50mm Full Carbon Clincher is designed as a versatile training and racing wheel that offers the greatest all around aero dynamics when including all riding and weather conditions. The deep 95mm rim is optimized for maximum aerodynamics at 43 km per hour (26.7 mph). The 95mm depth and rim design is proven to be the most aerodynamic at this speed over all other depths. Going deeper only ads more weight and does not reduce more drag, unless it is a full disc.
We collaborate with Zipp on the disc wheel, since the version we use is not only the lightest disc ever made (945 grams), it is also the most aerodynamic.
The bicycle wheel industry is small, so most of us know each other well and collaborate on design and aerodynamic testing, so do not be surprised to find Gray design features in other high end wheel brands.
Ever since triathlons inception, there has been a discussion on what the most aerodynamic and effective wheel combination is. There has been lots of misinformation in this area, so here is bottom line:
We also offer two new race wheel options: The SLX and the CSX. The SLX is our new sub 1100 gram wheel set designed for lighter, professional riders. The CSX is a carbon spoked version of the SLX that can handle more weight, yet yields the same ultra low drag.
