Basso Diamante SV review: A Colnago contender that's €900 too cheap

Fabulous handling, beautiful to look at, but own-brand wheels on an €11k bike is madness

A lovely bike with sublime handling that is marred by a poorly designed cockpit and in need of some more expensive wheels.

Once again I find myself facing a blank page, trying to find a way to tactfully write buying advice for a bike that is far beyond the realm of affordability for so many of us, during a cost of living crisis. I am, however, always reminded when trying to write these reviews of primarily Italian superbikes that when I was 14 years old I would happily read Top Gear magazine for hours, scraping together my pocket money to buy some new cranks and a far cry away from being able to put a downpayment on a Ferrari. For some of you, I’m sure this is a way to live vicariously and get a taste of what it's like to ride something that is clearly in 'dream bike' territory.

The Diamante SV, the ‘Super Veloce’ version of the Bassano-based brand’s range-topping road bike, is premium, and while it makes some light-hearted aero claims it’s far more a bike that rubs shoulder with the Colnago C68 than it does with something like the truly race-oriented Bianchi Specialissima

ValueMadly, I think it's good value. If you want an italian superbike that's going to turn heads then it's a relatively cheap way to do it8/10
