DimondCarbonado
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.

Our verdict
Overall
out of 100, average of 7 categories
The most affordable Dimond, sold complete with a 1x drivetrain and the brand's seat-tube-free beam frame. The 11-speed groups, TRP Spyre-C disc calipers and alloy wheels are basic, there is no built-in storage or hydration, and the seat angle is fixed.

Good to know
Design
The Carbonado is built exclusively for 1x drivetrains; Dimond says this lets the slim down tube leave air undisturbed.
SourceDesign
Dimond says its cantilevered beam frame, with no seat tube, absorbs road vibration and removes three leading edges found on conventional frames.
SourceHistory
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.
SourceVersions
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).
