9.5 Carbon Clincher - Rear

• 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.
• Structural strength is so important to GRAY that their engineers made it their primary focus. All of this has led to the production of an amazingly solid, strong and stiff rim that can handle a rider up to 240 lbs, while still maintaining an extremely light weight.

• 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.

• QUICK RELEASE: The Ti Quick Release Skewers are included with your wheel set and are among the lightest in the world at only 43g per set. Axles are made of 6/4 titanium alloy and the bolts and handle from 7076 Aluminum. They come in an assortment of colors and are good for road and MTB.
• BRAKING SURFACE: The braking surface is made from Basalt and features a stronger and more durable surface than just clear coated carbon. It is known for it’s heat resistant properties and has a Wear-Thru-Rate of at least 40,000 kilometers.

• QUALITY CONTROL: All GRAY products are thoroughly tested and quality checked. We use only the highest standards and best practices. New testing equipment was purchased as part of our latest production agreement with our factory.

• AERODYNAMICS: By using a combination of moderate tordial design, bladed spokes, internal nipples and low profile hubs, GRAY wheels are able to perform with the lowest drag ratios of all other brands. Please read about the independent third party testing of our wheels in the Technology section of our site.
• HAND BUILT: All GRAY wheels are hand built. What that means is that the carbon is laid by hands into the molds, the hubs are assembled by hand and the spokes are laced by hand. Every single wheel is quality controlled by two separate controllers and backed by our world’s best warranty.
