◂ Spokes ▸
Carbon spokes CS1 weigh 2.9g/pc, 3.2g plus aluminum nipple (1.8g lighter than Sapim CX-Ray spoke with nipple).
If choose carbon spokes to CS2 (5.5mm width), Weight +10g/pair.
The carbon spoke provides both higher stiffness and better fatigue life compared to the traditional steel spokes.
The max spoke tension of the carbon spoke is 528kgf according to our in-lab test, which is much higher than regular steel spokes (typically under 400kgf).

Carbon Fiber MaterialThis series carbon road 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 road carbon 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 WidthWith a 21mm internal width, such road bike 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. |  |
Undulating Rim DepthThe mid-depth rim profile varies by 5 mm in a wave pattern to improve aerodynamic efficiency and crosswind stability. This design enhances bike handling, delivering a faster and more confident riding experience. It also helps increase overall rim stiffness and 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. |

ProX C67DB HubsProX C67DB road hubs are designed to deliver high performance at an accessible price point. They feature a ratchet freehub mechanism paired with ceramic bearings for smooth and efficient operation. Custom logo etching is available upon request. |  |
ProX Carbon SpokesProX full carbon spokes CS1 (3.1 mm) and CS2 (5.5 mm) are utilized. Compared to traditional steel spokes, carbon spokes offer improved aerodynamics, higher stiffness, and enhanced fatigue resistance. Their optimized aero profile, combined with high elasticity, helps reduce drag and improve efficiency. |
 |
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. |
