FAQs

• Q: Are 25mm wide carbon rims better than 23mm for aerodynamics?
  A: 25mm width supports wider tubular tires for improved aerodynamic pairing with 23–28mm tires; commonly results in smoother airflow and greater stability at speed per multiple wind tunnel tests.
• Q: What is the actual weight per rim and why does it matter?
  A: Verified at 460g ±15g per rim. Lower weight reduces rotational mass for improved acceleration and climbing during races.
• Q: Is this rim still worth it over a clincher for racing?
  A: Tubular rims remain popular among professional teams for low system weight and improved ride feel in certain race conditions, but require dedicated gluing and tire management.
