◂ Rims ▸
For disc brake carbon rims, the design goes beyond simply removing the brake track. The carbon lay-up must also be refined to reduce weight, ensuring the overall system remains lightweight and competitive. The PRD28 series (ProX Road Disc, 28 mm external width) rims are constructed using premium Toray T700 and T800 carbon fiber, combined with a stable resin system to form a strong and lightweight foundation. The lay-up structure is further optimized by minimizing excess material wherever possible, while reinforcing high-stress areas such as the spoke holes. This approach achieves an effective balance between weight reduction and structural integrity. As a result, these rims deliver a lightweight build without sacrificing stiffness or strength.
The PRD28 series features a 28 mm external width (21 mm internal width) and are compatible with 700×28C-45C tires. Multiple depths are optional: 33 / 38 / 44 / 50 / 55 mm. Whether you prefer a shallow profile for climbing or a deeper rim for speed on flat terrain, the range offers a suitable option for different riding styles.

◂ Hubs ▸
- High end DT Swiss 240 EXP disc brake hubs, light and reliable carbon gravel wheelset for racing.
- Ratchet EXP 36 freehub system provides best reliability. Straight spring and increased bearing distance creates longer lifetime. power transmission.
- Front Hub 12/100mm TA & Rear Hub 12/142mm

◂ Spokes ▸
High-end Sapim CX-Ray spokes are among the top-tier spokes on the market.
The Sapim CX-Ray spoke achieves a perfect blend of light weight, strength and flexibility, and delivers outstanding results in fatigue resistance testing.

	Carbon Fiber Material Our road carbon rims are manufactured using premium Toray T700 and T800 carbon fiber, combined with a stable resin system to ensure consistent quality and a lightweight structure for road cycling.		Light Weight Design A carefully engineered lay-up structure using Toray T700 and T800 carbon prepreg enables a lightweight carbon road rims. Excess material is minimized to reduce weight, while reinforcement around the spoke holes ensures structural strength. The result is low weight without compromising strength or stiffness.
	Wider Inner Width With a 21mm internal width, these carbon rims are optimized for modern 700×28C–35C tires and remain compatible with even wider tires. The increased width provides better tire support, simplifies installation and removal, and enhances traction and cornering stability.		Aero U-Shape Profile The wide U-shaped rim profile offers improved aerodynamic efficiency compared to traditional V-shaped designs, helping to reduce drag at higher speeds. It also enhances airflow stability in crosswinds, while contributing to increased stiffness and overall structural strength.
	Bead Lock Design Subtle ridges along both sides of the carbon rim channel—known as bead locks—help facilitate easier tubeless tire inflation. Combined with a hooked bead design, they ensure a secure tire fit and reduce the risk of blowouts.		Tubeless Ready Tubeless setups are increasingly popular for road bike wheelset due to improved grip, lower rolling resistance, and enhanced comfort. All of our carbon clincher road rims are tubeless compatible while still supporting standard inner tubes. An optimized anti-burp profile ensures straightforward tire installation, removal, and inflation.
	DT Swiss 240 HubsDT Swiss 240 EXP hubs deliver high-end performance with excellent durability. The Ratchet EXP 36 system enhances reliability, while the optimized internal design extends bearing lifespan.		Sapim CX-Ray SpokesPremium Sapim CX-Ray spokes are widely regarded as among the best in the industry, and are commonly used in premium disc brake wheelsets from leading global brands. They offer an excellent balance of super light weight, strength, and flexibility, with outstanding fatigue resistance.
	Disc BrakeDisc brake provide more precise and consistent braking than rim brakes. These carbon rims are purpose-built for disc use, eliminating the brake track and avoiding heat-related issues. A dedicated carbon lay-up enhances durability while keeping weight low.		2-Year Warranty Our production process includes strict quality control and comprehensive testing to ensure reliable performance. All ProX carbon rims and wheels are backed by a 2-year warranty from the date of delivery. Full details are on our Warranty Policy page.
