The Bianchi Arcadex PRO GRX 820 is a premium carbon gravel bike that blends Bianchi’s legendary Italian racing heritage with modern gravel performance. Built with a full high-modulus carbon frame featuring Bianchi’s exclusive Countervail® vibration-damping technology, it delivers exceptional stiffness, lightweight construction, and superior comfort on rough gravel, dirt roads, or long adventures.

Equipped with the reliable Shimano GRX 820 2×12 mechanical groupset (50/34T crank, 11-34T cassette), it offers precise shifting and powerful hydraulic disc braking tailored for gravel. Wide tire clearance (up to 700×45C or 650b×2.1) and stable geometry make it versatile for racing, bikepacking, or everyday gravel riding. The integrated cockpit, internal routing, and thoughtful details (including a threaded BB and UDH compatibility on select builds) ensure clean lines and future-proofing.
