Triathlon2026Disc brakesNot UCI legalDiscontinued

Dimond's entry-level beam-frame triathlon bike, sold complete. It is built only for a single chainring, which lets Dimond keep the down tube slim, and keeps the brand's seat-tube-free layout that it says reduces road buzz and removes leading edges. Builds use 11-speed Shimano 105 or Ultegra Di2 1x with TRP Spyre-C disc brakes on Dimond's Disc Super Fork.

Good to know

  • Design

    The Carbonado is built exclusively for 1x drivetrains; Dimond says this lets the slim down tube leave air undisturbed.

    Source
  • Design

    Dimond says its cantilevered beam frame, with no seat tube, absorbs road vibration and removes three leading edges found on conventional frames.

    Source
  • History

    By November 2026 the Carbonado product page on Dimond's store no longer loads and the bike is gone from Dimond's triathlon-bike collection, which lists only the Mogul, Ikon and Marquise; the site menu still links the old page. Treated as no longer sold new; Dimond hasn't announced a replacement.

    Source
  • Versions

    Listed upgrades include Red Crown Carbon 60/88 wheels (+$1,400), Profile Design Svet (+$400) or Red Crown Monarch (+$800) aerobars, SLF or Enduro ceramic bearings and a ROTOR InSpider power meter (+$900).
