Planet X Maratona

Maratona Carbon Road Bike

The Planet X Maratona blends High Modulus carbon fibre with precisely engineered frame layup to create a bike that offers day-long riding comfort , pedalling efficiency and the potential for effortless hill climbing.

Our Sportive geometry uses longer chainstays to enhance high-speed stability, making the Maratona a predictable descender on fast alpine passes. We've selected a mid-length headtube that provides a more comfortable riding position but doesn't stray into sit-up-and-beg territory, flip the stem if you want the armchair comfort option!

Our lightest ever Endurance bike, the Maratona is ready to carry you to your Sportive goals.


  • Sportive Geometry
  • High Modulus Carbon Fibre
  • 995g Frame Weight
