ProX Ultra Light Full Disc Carbon Wheel 27mm Wide Disc Brake Aero Rear Disc Wheel For TT Bikes

Ultra-Light. Non-Paint. Aerodynamic Advantage.
A new carbon disc wheel engineered for TT, Triathlon, and Track racing—only 970g, raw UD carbon finish, ceramic bearings, and optimized wide-rim aerodynamics.

Time Trial, Triathlon and Track bikes, full disc wheel, 5-spoke and 3-spoke carbon wheels are widely used.

Compared to regular wheels, carbon spoke and full disc wheels are relatively heavier, but they are outstanding in aerodynamics and stiffness which are critical for TT/Track bikes.

ProX Carbon had taken it to the next new level in terms of rim finish. Non-paint (paintless) finish become one of the choices. They feature the latest manufacturing technology and are the completed product when come out of rim molds directly, eliminating the need for coating or painting. Such carbon rims are of better scratch resistant, near flawless look and visible original carbon fiber weave. Non-paint looks more premium to match the carbon bike than the matte finish. No paint, more carbon, pure performance.

Different carbon weave apperance optional (see below picture).

27mm outer width is an absolute and perfect choice to follow latest popular tendency in the carbon bike market. 21mm inner 27mm outer width, optimized aerodynamics for 700x28C tires.

The valve hole is on the non-drive side and equipped with a sticker. It keeps the valve clean and of better looking. The most important benefit is to reduce wind resistance and noise.

Good quality OEM PX hub is made by well selected hub manufacturer in Taiwan. It is designed with ratchet 36T freehub system which improves power transfer efficiency, combining with ceramic bearings, the rolling resistance is minimized. Such hub helps you to shorten acceleration time and save energy. Ceramic bearings are smoother, rounder and with more uniform size. In that case, the friction is reduced and that can contribute more energy to the wheels. Ceramic bearing is also harder than steel bearings (up to 30%), which improves durability, and they also don’t rust for less maintenance. All of them are center lock disc brake, Shimano 11/12s or SRAM 12s XDR freehub available.

✅Ideal For:

• Triathletes looking to maintain high speed with stable airflow
• Time Trial riders seeking maximum aerodynamic advantage
  
• Track cyclists who require stiffness and consistent power transfer
  
• Performance-focused racers where every watt and every gram matters
• Riders competing on flat or fast courses with minimal technical climbing

❌Not Recommended For:

• Daily commuting or casual riding
• Very windy conditions for inexperienced riders
  
• Riders who prioritize comfort over performance
