{"product_id":"bianchi-arcadex-pro-grx-820-822-1x","title":"Bianchi Arcadex Pro GRX 820\/822 1x","description":"\u003cdiv\u003e\n  \u003cp\u003eThe gravel category has divided cleanly into two camps: bikes optimized for speed on mixed terrain, and bikes built for the rider who wants to go somewhere they've never been. The \u003cstrong\u003eBianchi Arcadex Pro GRX 820\/822 1x\u003c\/strong\u003e is the latter. Bianchi has been building bicycles since 1885, and the Arcadex sits at the exploratory end of their current lineup — distinct from the Impulso range, which handles their race-oriented gravel work. The Arcadex Pro is built for riders planning multi-day routes, overnight bikepacking trips, and long days spent figuring out what's past the point where the gravel turns to dirt.\u003c\/p\u003e\n\n  \u003cp\u003eThe frame is SM Carbon Fiber Composite built around an endurance geometry — higher stack and longer front-center than a competition-focused gravel bike, calibrated for day-after-day comfort without sacrificing handling on rough surfaces. The frame is rated for ASTM 2 off-road usage and is designed to accept a compatible suspension fork if you want more capability on rougher terrain down the road. Fully internal cable routing is standard on the Pro, managed through a Bianchi Custom Acros ICR headset that keeps housing clean and the frame lines uncluttered. Tire clearance reaches 700c x 50mm, with fender and mudguard mounts incorporated for all-season riding. Two bottle cage bosses sit within the main triangle. Integrated into the downtube is the Internal Frame Storage module — a sealed compartment accessible from outside the frame, fitted with a fabric pouch to hold CO2 canisters, tire levers, energy bars, or a small multi-tool without rattling against the carbon shell. Hidden inside the rear thru-axle is a 4, 5, and 6mm hex key, providing field-ready tools without adding weight to your kit. The rear dropout is SRAM UDH-compatible for broad derailleur compatibility and straightforward hanger replacement.\u003c\/p\u003e\n\n  \u003cp\u003eShimano GRX 820\/822 handles the drivetrain in a 1x, 12-speed configuration. The front derailleur is absent by design — fewer moving parts to maintain when you're far from a shop, and a cleaner setup for technical riding where hand position changes frequently. The GRX 822 rear derailleur handles cassettes up to 51T and works here with a 10-51T cassette that covers steep climbs with a loaded frame bag and moves efficiently on longer flat stretches. The GRX 820 hydraulic lever manages both braking and shifting at each hand. Shimano BR-RX820 hydraulic calipers run Shimano RT70 IceTech Centerlock rotors at 160mm front and rear. Crankarm length is size-specific: 170mm on XS and S, 172.5mm on M and L, 175mm on XL.\u003c\/p\u003e\n\n  \u003cp\u003eWheels are Velomann Terbium carbon clinchers — 30mm rim profile, 25mm internal channel, and tubeless-ready. The wide internal width supports the stock 700x45 Pirelli Cinturato Gravel M Classic at lower pressures, and going tubeless on this bike is the right call: lower psi improves traction and compliance on loose terrain without the pinch flat risk. The Cinturato M Classic has a tan sidewall and a tread pattern suited to loose gravel, packed dirt, and mixed surfaces — a tire choice that reflects what the Arcadex is actually for, rather than what looks fast in a spec sheet. The cockpit is all Velomann alloy: a Gravel ICR handlebar with 16-degree flare, 70mm reach, 130mm drop, and internal cable routing through the bar itself. Bar width scales by frame size — 400mm on XS and S, 420mm on M and L, 440mm on XL. The 16-degree flare widens your grip in the drops for better control on rough terrain and technical descents. The Velomann Mitora 149 H1 saddle is 149mm wide with an open-channel design, foam padding, and AISI steel rails — dimensioned for all-day comfort rather than minimum weight. La Spirale Ribbon Cork bar tape finishes the cockpit.\u003c\/p\u003e\n\n  \u003cp\u003eThe Arcadex Pro comes in two colorways — CK16\/Green Water Matte, with Bianchi's iconic Celeste, and Forest Green\/Graphite Matte — in five sizes from XS through XL. A dedicated line of Bianchi ORMA bikepacking bags is available separately, designed specifically for the Arcadex's frame mounting points. At $4,600, the bike arrives ready to ride. Pedals are not included.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Bianchi","offers":[{"title":"AF - CK16 \/ Green Water Matte \/ XS","offer_id":43652328357932,"sku":"YTB85IXSAF","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AF - CK16 \/ Green Water Matte \/ S","offer_id":43652328259628,"sku":"YTB85ISMAF","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AF - CK16 \/ Green Water Matte \/ M","offer_id":43652328226860,"sku":"YTB85IMDAF","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AF - CK16 \/ Green Water Matte \/ L","offer_id":43652328194092,"sku":"YTB85ILGAF","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AF - CK16 \/ Green Water Matte \/ XL","offer_id":43652328325164,"sku":"YTB85IXLAF","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AW - Green \/ Graphite Matte \/ L","offer_id":44045164314668,"sku":"YTB85ILGAW","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AW - Green \/ Graphite Matte \/ M","offer_id":44045164347436,"sku":"YTB85IMDAW","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AW - Green \/ Graphite Matte \/ S","offer_id":44045164380204,"sku":"YTB85ISMAW","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AW - Green \/ Graphite Matte \/ XL","offer_id":44045164412972,"sku":"YTB85IXLAW","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"AW - Green \/ Graphite Matte \/ XS","offer_id":44045164445740,"sku":"YTB85IXSAW","price":4600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/bianchi-arcadex-pro-grx-820822-1x-7462662.jpg?v=1771302249","url":"https:\/\/ricycles.com\/products\/bianchi-arcadex-pro-grx-820-822-1x","provider":"RA Cycles","version":"1.0","type":"link"}
