Basso Diamante frameset review

A year-long journey with the Basso Diamante - here's the final word...

Cycling Weekly Verdict

The Basso Diamante has been my companion for just shy of a year, serving as a familiar testbed for other components. The 1977 founded Italian brand has provided a well-balanced ride quality with excellent handling. The geometry is aggressive, this is a chassis for a rider who likes to get low at the front end - and the frame weight means it's not a recommended choice for those who live by the scales. But if you're happy to carry a few extra grams, or save them elsewhere, then the Diamante is definitely one to add to the shortlist.

Basso was one of the earliest adopters of carbon fibre in bicycle manufacturing and it is one of few Italian brands that has kept its production process almost entirely in Italy. That's paid off well amidst the Covid pandemic and accompanying bike drought, with smaller batch production enabling quick reactions. It also pays off in terms of attention to detail - and the allowance for a few flambounancies in design.

The Diamante is Basso's race machine. Its geometry is more aggressive than the recently redesigned and more aero SV version - which was toned down a little bit to allow more riders to slam the front end and make use of the recessed headtube designed for this purpose.
