Frame Size


Quintana Roo designed the PRthree for triathletes looking to achieve their next PR. The PRthree is an elite level bike, sharing some of the same aerodynamic properties of our other PRseries bikes, like SHIFT+ technology, with a slightly different carbon layup & budget-friendly componentry.

The PRthree is lighweight, aero-efficient, stable and mechanically easy to work on and travel with. We keep the bike simple so you can focus on achieving your goals.

Key Features

  • SHIFT+ technology
  • 24T carbon-fiber frameset
  • Boat tail cross sections
  • Static downtube orientation 
  • QR aero storage containers
  • Simple wrenching and maintenance

  • We pair each Quintana Roo frame with some of the best components and drivetrains in the world. We take component specifications seriously, as the quality and performance of the components are just as important as the frames we design and produce.

    If you have any questions or would like to request custom component specifications, please contact us.
