◂ Spokes ▸
Using the popular Pillar PSR AERO 1423 spokes.
The spokes are manufactured using Pillar's patented cold forging technology, increasing strength by up to 20%.
Featuring an aerodynamic streamlined design, they offer excellent elasticity and a low drag coefficient.
 |
Carbon Fiber MaterialThis series carbon road rims are manufactured using Toray T700 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 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 light weight without compromising strength or stiffness. |
 |
Relatively Narrow Inner Width With a relatively narrow 18mm internal width, these road rims are optimized for 700×25C–35C tires and remain compatible with even wider tires. For conventional bikes that have limited tire clearance, this rim design offers better tire fitment and makes tire installation and removal easier. |  |
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. |

ProX C52DB HubsProX C52DB hubs provide reliable performance at a competitive price. Equipped with a 36T ratchet freehub system and ceramic bearings for consistent engagement and smooth rotation. Custom logo etching is supported. |  |
Pillar SpokesPillar PSR AERO 1423 spokes are a popular choice for performance wheelsets. Their patented cold forging process increases strength by up to 20%, while maintaining a lightweight aero profile. Effective combination of elasticity, durability, and aerodynamics. |
 |
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. |
