Bianchi Arcadex Pro - GRX 820/822 SGS 1x12sp

Ride deeper into the wilds. The Bianchi Arcadex PRO is a modern adventure-gravel machine designed to take you further beyond your usual routes—combining Bianchi’s racing heritage with rugged, expedition-ready capability. It’s built for fast gravel, long mixed-surface days, and bikepacking escapes where reliable handling and smart integration matter.

Built to explore: the Arcadex platform

The Arcadex family is designed around advanced exploration: stable, confidence-inspiring handling for long-distance rides, plus practical features that support self-sufficient adventures. The dedicated carbon frameset uses an endurance-focused geometry for back-to-back days in the saddle, and keeps the bike looking clean with fully integrated routing.

Adventure-ready integration you’ll actually use

• Internal Frame Storage (IFS) for essentials like CO₂, levers, snacks, multi-tool, or small spares
• Protective tool pouch designed to fit the IFS neatly and prevent rattling
• Rear axle hex tool integrated into the rear thru-axle (4/5/6 mm Allen) for trailside fixes

Bikepacking-friendly mounting and tire clearance

Arcadex is built with multi-day escapes in mind. The platform supports accessories and bikepacking luggage, and offers generous tire clearance—up to 700c x 50 mm—with compatibility for clip-on fenders/mudguards. That means more grip, comfort, and control when the route gets rough.

Option to tame the trail

For riders who want extra comfort and control on rugged terrain, Arcadex PRO is also offered in versions compatible with a suspension fork setup (RockShox Rudy XPLR with 30 mm travel on select builds). The platform can be upgraded post-purchase with a compatible suspension fork.

Why Arcadex PRO (GRX 820/822) makes sense

This build is centered on Shimano GRX 820/822 mechanical shifting in a 1x12 configuration—simple, durable, and ideal for gravel. The wide-range gearing helps you stay seated on steep climbs while keeping speed on the flats.
