FAQs

• Q: What are the benefits of a 30mm inner wide tubeless carbon rim?
  A: Supports wider road tires for lower rolling resistance, better grip, and improved ride comfort—especially at lower pressures.
• Q: Is a 50mm carbon rim suitable for climbing and flat races?
  A: 50mm offers a balance of aerodynamic benefit for flats and moderate weight, with the EL and UL variants better for climbing scenarios.
• Q: Is the weight difference between Superlight and Ultralight significant?
  A: The ~40g reduction affects acceleration and climbing; however, lighter options reduce maximum rider weight limits and slightly increase the risk of impact damage in heavy-duty use.
• Q: Do 36mm outer width rims improve aerodynamics?
  A: The 36mm width is aerodynamically profiled to optimize airflow around wider tubeless tires while supporting stiffness without excessive weight.
• Q: What certifications or testing does this rim meet?
  A: Each rim passes forward compressive (>300kg), lateral torsion (>50kg), and spoke hole tension (>280kg) strength tests, with strict flatness (<0.15mm) and roundness (<0.3mm) tolerances for predictable, stable wheel builds.
