DimondIkon
A beam-frame triathlon bike that Dimond positions between the Marquise and the Mogul. It takes a smaller version of the Mogul's down-tube cowling around the front wheel and keeps the Lunch Box bento and TOTES flat-kit storage, with no seat tube. It is sold as a custom-painted frameset or custom build direct from Dimond.

Our verdict
No overall score: there's no complete-bike price to rate
A cheaper route to the Mogul's wheel-cowling idea with a lighter frame, the same big bento and flat-kit box, and custom paint. Like the other Dimonds it is frameset-only with a fixed seat angle and no hydration, and Dimond publishes no aero figures for it.
