The Bianchi Arcadex GRX 810 is a high-spec edition of Bianchi’s original carbon gravel disruptor. While the newer "Next Gen" Arcadex focuses on integration and storage, this version is beloved for its raw power transfer and the legendary reliability of the Shimano GRX 800-series mechanical groupset.
In Size Small (SM), the Arcadex is particularly nimble. Its compact rear triangle and beefy carbon fork make it feel incredibly reactive when climbing out of the saddle or weaving through technical singletrack. The Celeste / Blue Note (GX) finish is a fan favourite, pairing the classic Bianchi turquoise with deep navy accents that highlight the frame’s unique, angular architecture.

Key Technologies
GRX 810 Ergonomics: The 810-series levers feature a textured "anti-slip" coating and a higher brake pivot point, allowing you to achieve massive braking power even when riding with your hands on top of the hoods.
Mudguard & Rack Compatibility: Despite its racing silhouette, the Arcadex has hidden eyelets, making it a viable option for fast, foul-weather commuting or lightweight credit-card bikepacking.
Asymmetric Chainstays: The drive-side chainstay is dropped to prevent "chain suck" and allow for the clearance of 42mm tires without lengthening the wheelbase, keeping the handling snappy.
Carbon Fiber layup: Optimized for "Gravel Racing," meaning it’s stiffer and more vibration-absorbent than an alloy frame, reducing hand numbing on long washboard roads.
