Classic lines and racing pedigree | The new Bianchi Impulso Pro has its eyes set on go-fast gravel riding

The Bianchi Impulso Pro gravel bike is available in two fabulous colours, but tyre clearance may be limiting for some

Bianchi Impulso Pro celeste

The Bianchi Impulso Pro is an all-new gravel bike focussed on gravel racing, matching a fairly aggressive geometry with – in the context of gravel bikes – a conservative 38mm maximum tyre width.


Originally, the Impulso existed in Bianchi’s range as an endurance road bike, before being updated to take on a wider spectrum of riding and being given the ‘All-Road’ moniker. For a while, it was the sole gravel bike in the line-up, but the last year or so has seen the brand expand its gravel offerings with the Bianchi Impulso E-Road and the Bianchi Arcadex.

Where the Arcadex is pitched more towards technical off-road riding, the Impulso Pro now fills in the faster end of the gravel spectrum for Bianchi.

Go-fast geometry

The geometry reflects this with steeper head tube and seat tube angles than the Arcadex. This is matched with a shorter wheelbase.

Bianchi says the geometry creates a “super-responsive and rigid ride” that reflects the brand’s racing pedigree. In a world filled with dropped chainstays enormous fork crowns, the Impulso stands out with a fairly traditional and clean silhouette.

Carbon frame and conservative tyre clearance

Whereas the Impulso All-Road has an aluminium frame, the Impluso Pro is only available with a full carbon frameset.

Bianchi quotes a claimed frame weight of 1,100g, but it hasn’t specified what size frame this weight is for, whether this is a painted frame or whether it includes any hardware.

Bianchi quotes a maximum tyre clearance of 38mm with 700c wheels for the Impulso Pro (confusingly, Bianchi also states 37mm elsewhere in its press release for the bike – we’ve asked for clarification). This is on the narrower side for the best gravel bike tyres, with 40mm being something of a de facto standard for most gravel bikes.

That relatively limited tyre clearance may put off riders who are more interested in gnarly off-road bikepacking adventures, but for those who like to ride fast on gravel roads or more mellow terrain, it may be sufficient.

Shimano GRX 1x and two colour options

At launch, the bike is available in a single Shimano GRX 600 build, set up with a 1× drivetrain with a 40t chainring and an 11-42t cassette. The bike is also compatible with 2× drivetrains via a removable front derailleur mount.

The Veloman wheelset is 24mm-deep, with a 21mm internal width. The rims are fitted with 37mm-wide WTB Riddler Comp gravel tyres.

Velomann also provides the handlebar, stem and alloy seatpost, while the saddle is from Selle Italia.

The Impulso Pro comes in two colour schemes. One takes Bianchi’s unmistakable signature celeste colour and introduces different shades for variation across the bike, and the other contrasts different sage greens.

The bike is available in six sizes (48cm to 58cm) and will cost £3,400. Further international pricing is TBC.
