First released 22 years ago, the Basso Diamante is the Italian marque’s longest-running road bike. The 2023 update looks to ensure that it stays relevant.

Now in its eighth iteration, the new Diamante remains a race-ready lightweight bike, well-suited to long climbs and technical descents. In fact, it’s lighter than ever before. According to Basso, the redesigned frame, made from Toray 40t and 30t carbon, weighs 200 grams less than the previous model. A 53cm frame has a claimed weight of just 760 grams, which Basso says allows for complete bikes to “easily” remain under the UCI’s 6.8kg weight limit.
