Bianchi’s all-new Arcadex carbon gravel bike lets the Italian bike maker fully embrace unlimited, quick gravel riding & off-road adventures once again. While Bianchi has long made gravel bikes, including steel gravel touring bikes I remember selling in a bike shop even twenty years ago, a fast-moving modern carbon gravel & adventure bike had been missing from the celeste lineup.

Now stepping out beyond all-road, the new Arcadex looks to be a fully capable, high-performance carbon gravel bike. The new carbon bike features oversized and dramatically shaped tube profiles that Bianchi says pulls aerodynamic optimization techniques from their aero road family. That includes little fork flap extensions and dropped seatstays, plus a hidden seatpost binder and mixed internal routing.

Interestingly, the Arcadex is NOT an e-bike, but you’d be excused for thinking it might be. Usually we see e-bikes that look almost like a regular bike. But this might actually be a regular bike, built up from a new e-bike frame -without the battery or motor… It has the characteristic oversized downtube we’ve seen of many recent rear hub-powered e-bikes, and even the oversized BB junction with a rubber plug that I can only assume could fit a charging port.

My guess is that we will see an eArcadex any day, powered an FSA System or Mahle eBikemotion rear hub.

Gravel Tech Details

One of the big aero additions is fully internal cable routing compatibility with an FSA ACR headset that allows all cables to be hidden. But not everyone wants to mess with complicated routing setups, so the new bike also includes more conventional modular cable routing ports on the downtube.

Large tire clearance was a priority for the new gravel bike, but Bianchi opted for fast gravel standards rather than pushing into MTB territory, sticking with up to 700x42mm or 650x47mm tires.

Many off-road dropbar bikes have gone 1x in recent years, but gravel doubles aren’t going away anytime soon, so the Arcadex gets a removable front derailleur mount too.

Just as important though was versatility, so the full carbon frame & fork get full coverage fender compatibility, plus mounts for a rear rack. There are also your standard suite of adventure mounts on the frame – two standard bottle cage mounts inside the main triangle, plus a set of bosses under the downtube and on top of the toptube.

The carbon Arcadex frame has a claimed weight of 1100g (size L, 55cm), plus 480g for the full carbon fork. The gravel frameset uses a PressFit BB86 bottom bracket, straight 1.5″ headset with a tapered 1.5-1.25″ steerer tube, and 31.6mm seatpost. It gets 12mm thru-axles & flat mount disc brakes, plus adaptable internal cable routing for mechanical or electronic and 1x or 2x groupsets.

The Arcadex is available in five sizes (XS-XL). Quick handling geometry is a bit inspired by Bianchi’s cross bike geo with a 71° head angle, 73.5° seat angle & short 425mm chainstays. But the gravel bike gets deeper 75mm bottom bracket drop for stability, and much more relaxed upright geometry – about 1cm shorter Reach across all sizes and almost 5cm higher Stack with the long 416mm a-c fork.

    I actually quite like the “muscular” looks, but BB86? C’mon.
    Ticks all my other boxes though: 2x, fender mounds, round seatpost, normal stem cabling.

    Bianchi have had ugly paint jobs (including the font) in their Allroad and CX bikes for a while now. This makes it clear that they’ve extended that to the frame design :/
