Basso Diamante 8th-gen goes longer and disc-only for 2023

New bike comes with a claimed 760g frame weight and longer front centre to add high speed stability

Basso has launched the new 2022 Diamante road bike. It’s the eighth edition of Basso’s all-rounder road bike, which it’s had in its range for over a span of 22 years, making the Diamante Basso’s longest-serving model.

Unlike the previous generation bike, where there was a rim brake option, the new Diamante is disc brake only.

Based near Bassano del Grappa in Italy’s Veneto cycling heartland, Basso makes the Diamante from a mix of 40t and 30t Toray carbon fibre. It says that the latest model has pared over 200g off the frame weight, with a size 53 frame weighing just 760g, allowing builds that come in comfortably under the UCI’s 6.8kg weight limit.

Unlike many of its competitors, Basso has kept the round tubing sections of the Diamante, rather than looking to add aero tube profiles. It says that this comes out of its own research on how to achieve the best performance from the carbon frame and helps ensure its torsional rigidity while reducing weight.

*Sizes in millimetres

Basso says that it has changed the Diamante’s geometry in the latest generation bike, lengthening the front centre by reducing the head tube angle.

The brand says that this increases stability at high speeds, while adding responsiveness at low speeds, so that the new bike performs better both uphill and on descents.

It should also reduce the likelihood of toe overlap with the front wheel, particularly for smaller sized frames.

The front centre of the outgoing model in the smallest size 45 frame was 574mm, but that’s increased in the new bike to 579.3mm.

For a mid-sized 56cm frame, the equivalent figures are 590mm and 593.5mm, while the largest 62cm frame’s front centre increases from 602mm to 606mm.

Stack has been increased slightly and reach has been decreased for a less stretched-out riding position.

Meanwhile the chainstay length has been kept at 400mm, which Basso says will allow riders to fit tyres of up 32mm width.

Integrated bar/stem

Basso has used its own component lines on the Diamante, including its one-piece bar/stem with internal cable routing into the bike’s frame.

Called the Levita, Basso says that a 420mm wide bar with a 110mm equivalent stem length weighs 330g.

It’s available in six sizes from 400mm wide/90 stem up to 420/130mm, all sizes having the same 119.7mm drop from the centre of the head tube clamp to the bottom of the bars.

There’s also a patented Basso-specific 3B Gen 2 seatpost clamp that’s hidden in the rear of the seat tube.

Basso says that the design helps to reduce vibration transmitted to the saddle as well as giving the Diamante frame a clean look.

The seatpost has a variable head geometry allowing either 0mm or 15mm setback to fine tune the ride position.

Basso Diamante specs and prices

Prices for the Basso Diamante start at €8,299 equipped with a Shimano Ultegra Di2 R8170 12-speed groupset and Basso’s own Microtech RE38 Disc 38mm deep, 23mm internal width carbon wheels.

There are details of other spec options on Basso’s website and you can also buy frameset only or as a build kit.

The Diamante is available in seven frame sizes from 45cm up to 61cm seat tube length.

Frame colour options are Opal White, Stealth and Candy Red, with Basso having its own paint formulation that it says is harder, less porous, more aerodynamic and more resistant to contaminants than its older paint formulations so it’s easier to clean.

The eighth edition 2022 Basso Diamante is available for purchase at authorised Basso dealers and direct from Basso’s website.
