Bianchi Specialissima Dura-Ace Di2 review

Specialissima is the name Bianchi has reserved for the very best of its best machines throughout the brand’s 137-year history.

The last Specialissima made a big impression on me back in 2016. It was a bike so, well, special that I successfully argued for it to become ‘Superbike of the Year’. It was all skinny, round tubes and featherweight materials (not to mention rim brakes). It looked and rode like the classic it became.

This Specialissima, a contender for our 2022 Performance Bike of The Year crown, is a very different-looking beast.

Firstly, and most obviously, it’s disc-brake equipped. It also, though, brings aerodynamics into the equation, using plenty of what Bianchi learnt from the Oltre and its Grand Tour stage-winning credentials.

Up-front, there’s a head tube that’s shaped almost to a point, which the fork crown meets seamlessly. The fork legs flatten and bow away from the front rim, reducing turbulent air and increasing tyre clearance into the bargain.

The front end is topped with FSA’s clever ACR bar-and-stem system, which routes all cabling through the bar, stem and down through the head tube. It’s not run-of-the-mill FSA, however, it’s Bianchi’s bespoke Reparto Corse iterations of FSA’s top-grade components.

The seat tube is gently aero-shaped too, and the rear stays follow the same subtle shaping, although they eschew the trend for all things dropped stay and meet the seat tube and top tube at an aero-tuned junction, replete with hidden clamp.

If you think all this shaping and styling, plus the addition of disc-brake fittings, adds weight, then the Specialissima chassis should surprise you. At just 750g (size 55cm) with a 370g fork, this is one very light basis for a superbike.

If you are of the full weight weenie persuasion, then you could forgo the classic Celeste colour (sacrilege in my eyes) and opt for the ultra-light black finish, which shaves a further 80g from the chassis.

As well as the classic Celeste colourway and the lightweight black option, Bianchi offers a ‘mermaid scale’ greenish blue, or you can choose from myriad custom colours through the Tavolozza custom programme.

The frame features Bianchi’s CV technology in its composition. This refers to countervail, a material Bianchi developed with US-based composites expert Material Sciences Corporation for the original Infinito CV that debuted at the 2014 Paris-Roubaix.

This patented material is produced by taking high-grade carbon fibre and using a viscoelastic material that’s sandwiched between hi-mod carbon layers in a unique layup.

Under testing (both on-road and in the lab), measurements have shown that the countervail material reduces the length of vibrations from the road surface by up to 80 per cent.

Bianchi Specialissima Dura-Ace Di2 specifications

The price and status of this bike means it’s all top-level components too.

Firstly, it showcases Shimano’s new 12-speed semi-wireless Dura-Ace Di2. This drives Vision’s grand-tour proven SC40 tubeless carbon wheels, wrapped up with Pirelli’s range-topping P Zero 26mm tyres.

The stem and bar are made in collaboration with FSA, with the Reparto Corse FSA stem crafted from 3D-forged and CNC’d 6061 aluminium and the bar made from UD (unidirectional) weave carbon.

Finishing things off is a Reparto Corse FSA K-Force light UD carbon post, topped with Fizik’s carbon-railed Antares R1 saddle.

The drivetrain mixes a 50/34 compact chainset with an 11-30 cassette. The new Dura-Ace shifts with the same accuracy as 11-speed Di2 was famed for. Shimano claims that front-derailleur shift speed is greatly reduced.

When you’re dealing with a fraction of a second reduced down to a slightly smaller fraction of a second, that’s quite hard to judge.

What I will confirm, however, is that the derailleur shifts impeccably. Even when out of the saddle and going for it, the derailleur never grumbles, drags or does anything beyond getting the chain from one chainring to the other.

The semi-wireless setup means the bike looks incredibly clean and slick. Though, with the ACR system and the frame design, you wouldn’t have seen the wires anyhow.

With both Shimano and SRAM now adopting wireless, I wonder how long it’ll be before bikes such as the Specialissima have no holes in the frame at all. The blanking plates being used throughout the frame do stand out from what is a very slick-looking bike.

The Vision SC 40 carbon tubeless wheels are excellent. They feel taut and responsive, and at 1,590g a pair they’re reasonably lightweight.

The rim, at 40mm deep and 25.5mm wide, is well shaped to match road tyres and the 19mm internal width is a great fit for the 26mm-wide Pirellis.

The SC40s are a £1,000 wheelset though, and on a bike that retails at over £11,000 you could rightfully argue that the Specialissima deserves something a little more special.

Bianchi Specialissima Dura-Ace Di2 geometry

The Specialissima is undoubtedly a performance bike. My 59cm test bike came with a 575mm stack height and 398mm reach. When you add in the 120mm stem and 20mm offset of the seatpost, it results in a bike that’s long and low.

It’s worth bearing in mind that this is certainly a bike designed for a racing mindset rather than recreational riding.

Parallel 73-degree angles are classic race-bike stuff, and the 43mm fork offset makes for a trail of 59mm. These are numbers that suggest a fast-handling bike, and those suggestions certainly bear fruit.

Bianchi Specialissima Dura-Ace Di2 ride impressions

Within minutes of being astride the Specialissima, I knew I was onto something very good. The chassis beneath me was all at once stiff and responsive, yet it feels lively – something that’s often amiss when it comes to flyweight stiff carbon bikes.

It accelerates with ease, as you’d expect a 7.1kg bike to, and when it comes to heading upwards the light weight makes it a mean companion. The handling is simply wonderful.

The steering requires so little effort because the front end is weighted perfectly. It means you can dart in any direction, so navigating through a busy pack or swiping between hazards on poor roads is never a challenge. It’s so responsive that such manoeuvres are all part of the fun.

With its light weight and rapid handling, the Bianchi is so far, so very superbike. It’s exactly what I’d expect of a bike of this calibre.

What’s less expected, however, is just how wonderfully composed and smooth the Specialissima is at all times. Often with a light, stiff bike and one running just 26mm-wide tyres (when it seems the roadie world has gone mad for big rubber), the trade-off is a rough, jarring ride on anything but the most pristine of road surfaces.

This Bianchi, however, glides over rough tarmac without complaint. Its ability to track straight and nullify vibrations makes this one of the best bikes to be riding when the road heads downwards.

It’s one mean climber too. I’ve ridden bikes in this year’s Bike of the Year designed with bigger tyres and comfort in mind that don’t handle the knocks as well as this brilliantly realised Bianchi.

Bianchi Specialissima Dura-Ace Di2 bottom line

With the Specialissima’s latest guise, Bianchi may have moved away from the origins of classic lightweight design by introducing some modern aerodynamic styling. For some, that may be a step too far from the purity of its predecessors.

However, it’s still a very handsome machine and one that absolutely doesn’t disappoint when it comes to the most important factor – the ride.

It’s a bike that’s all at once fast, flighty and incredibly nimble, yet composed and confident when riding on sub-optimal surfaces or pushing yourself to the limit.

It’s a bike I found myself wanting to live up to, not a bike I felt like going for a bit of a cruise on. It’s a bike I wanted to get up to speed and keep it there for as long as possible.

It’s a bike that, knowing you’ll be riding it in the morning, you’ll concentrate on getting a proper rest, eating well and turning down that beer or wine with dinner. You’ll want to be at your best to make the most of what’s one of the best bikes I’ve tried in a long time. It’s long, low and luxurious, and I’m smitten.

Even with all of my gushing accolades for the Specialissima, it’s one very, very expensive bike. It is stacked with great kit and a superb drivetrain, but some elements could be better.

The Vision wheels are super, but you can find them on bikes for much, much less. I would have expected Vision’s flagship Metrons on the Specialissima, if we’re staying on brand.

I could, however, live happily with the SC40s if it meant riding this chassis every day.
