All of our GRAY wheels are handmade from high modulus carbon. Each rim is designed to give you maximum aerodynamics and minimum weight, while still retaining incredible structural strength.
RIM DESIGN: All GRAY wheels are handmade from High Modulus Carbon. Each rim is designed to give you maximum aerodynamics and minimum weight, while still retaining incredible structural strength.
Structural strength is so important to us that our engineers have made it our primary focus. All of this has led to an amazingly solid, strong and stiff rim that can handle riders up to 275 pounds while still maintaining an extremely light weight.
SPOKES: At GRAY we only use two brands of spokes: Sapim and Pillar. The 45CC uses the RX Bladed Stainless Steel Spoke, which is not only one of the most aerodynamic, but also by far the strongest. All nipples are internally mounted making for a clean and more aerodynamic surface.
SHAPE: The 45CC has a moderate tordial shape which has been proven by third party independent testing to be the most aerodynamic. The sidewalls are made from 7 independent layers of carbon and offer incredible lateral strength.
BEARINGS: All GRAY wheels come standard with Hybrid Ceramic Bearings and Ezo bearings from Japan. It is a fully sealed Ezo bearing with steel balls for extremely high roundness accuracy and very low surface roughness, which enables accurate and smooth rolling element performance. The inside chase is made from uniformal-hardness ceramic or high carbon chromium steel.
FULL CARBON CLINCHER: The all Carbon 45CC is designed to absorb overheating from braking during long descents. The tubular portion of the rim has an extremely high heat tolerance and dispersement, which allows for heat to build up in the rim bed as opposed to the sidewall. This design feature reduces the risk of overheating the rim.
