FAQs

  • What is the recommended carbon rim depth for triathlon on flat courses?
    75mm or greater is optimal for aerodynamic efficiency at sustained speeds—this rim is tailored to that use-case.
  • Is the 75mm deep clincher rim challenging to control in crosswinds?
    While deeper rims can be more susceptible in strong crosswinds, the U-profile and 25mm width balance speed with handling stability. Suitable for most competitive events.
  • What size tire is recommended?
    Best suited for 25C or 28C clincher tires; improved aero shape and rolling resistance vs. narrower options.
  • Is this rim tubeless compatible?
    No, this model is clincher only. Tubeless capability is available in alternative rim models.
  • What certifications or testing has this rim passed?
    Manufactured using ISO-compliant carbon fiber layups and subjected to static/dynamic load testing (in-house; not third-party certified).
