Bianchi Arcadex GRX600 40 Gravel Bike 2021
With a sculpted carbon frameset and off-road capability, the Bianchi Arcadex GRX600 40 Gravel Bike is ready to inject some Italian flair into your gravel rides. Designed to deliver the distinct Bianchi feel on all terrains, the Arcadex is built for modern adventure cyclists and sees a host of technical features help riders tackle rough terrain. The frame is sleek and aerodynamically optimised, and offers clearance for up to 700×42cc or 650×47cc tyres, to provide grip and compliance on harsh terrain. To ensure a consistent feel across the size range the chainstay length varies by frame size, with the stable geometry providing a confidence-inspiring platform for technical rides.
Mudguard eyelets add versatility, allowing the Arcadex to be the perfect choice for fast, multi-day bikepacking adventures. The dedicated seatpost and stem spacer design add a sleek aesthetic, supplying the bike with an integrated look. The 1 1/8th to 1.5" tapered head tube is stiff and stable, particularly under braking, and the hydraulic disc brakes deliver great poor-weather performance.
Durable and purpose-built, the Shimano GRX600 drivetrain is designed to cope with the rigours of gravel riding. A wide 11-42t cassette flattens hills, with the 11-speed drivetrain providing a wide range for all gradients and situations on the trail. The AlexRims GD24 rims are strong enough to survive seasons of abuse and are tubeless-ready to make converting from tubes a possibility.
