700C 50mm Asymmetric Carbon Road Rim — 36mm Outer / 30mm Inner, Tubeless Ready, Weight Options (SL, UL, EL)

Take control of speed, stability, and comfort on long road rides and mixed-surface events with a rim engineered for modern tubeless setups and wider tires. The 700C 50mm asymmetric carbon rim balances aerodynamic advantage with tire support so you can hold faster lines and ride with greater confidence across varied road and gravel conditions. Available in multiple weight options, it adapts to priorities from all-day endurance to climbing-focused performance.

700C 50mm Asymmetric Carbon Rim - Designed for road and gravel performance

The asymmetric 50mm profile with a 36mm outer and 30mm inner width is tuned for 28–35mm tubeless tires, improving tire support, contact patch stability, and aerodynamic interaction with wider road rubber. Riders experience lower rolling resistance and increased grip at lower pressures while retaining predictable handling at speed.

Built from T700/T800 unidirectional high-modulus carbon fiber, the rim reduces rotational mass for quicker acceleration and more responsive handling without sacrificing the stiffness needed for efficient power transfer. The asymmetric offset cross-section evens spoke tension, enhancing wheel durability and lateral stiffness for consistent performance during hard efforts and technical descents.

Why it fits your routine

• Optimized for tubeless road and gravel tires: 30mm internal width supports 28–35mm tubeless tires for better traction, lower rolling resistance, and improved comfort at lower pressures.
• Aerodynamic yet practical 50mm depth: 50mm depth provides aerodynamic benefit on flats while the 36mm outer width smooths airflow around wider tires for real-world gains.
• Material and layup: High-modulus T700/T800 unidirectional carbon construction balances lightness and structural integrity for reliable ride quality.
• Multiple weight variants: Choose Standard (495g), Superlight SL (455g), Ultralight UL (415g), or Extreme Light EL (400g) to prioritize durability or climbing performance, noting each variant has a specified rider weight limit.
• Tested strength and tolerances: Passes forward compressive (>300kg), lateral torsion (>50kg), and spoke hole tension (>280kg) tests with flatness <0.15mm and roundness <0.3mm for predictable wheel builds.
• Compatibility: Made for 700C/ISO 622 road and gravel bikes and compatible with modern Shimano and SRAM hub standards.
• Balance of performance and reliability: Asymmetric design improves spoke tension distribution and wheel longevity while maintaining the stiffness needed for efficient power transfer.

Choose lighter variants for reduced rotational mass and quicker acceleration, keeping in mind reduced maximum rider weight limits for SL, UL, and EL options; select the Standard variant for higher load capacity and broader durability where impact resistance is a priority.
