Bianchi Zolder Pro GRX600 Disc Cyclocross Bike 2022
Built ready for the professional CX circuit, the Bianchi Zolder Pro GRX600 Disc Cyclocross Bike is designed for aggressive riding on mixed terrains, be that mud, sand or grass. A few updates for the season include a higher bottom bracket for better clearance, a redesigned rear triangle for almost instant power transfer and lower seat tube cage bosses to make shouldering the bike more comfortable. There's also clearance for wide 40mm tyres. The carbon frame and fork are light and stiff, with 'cross-specific geometry for precise handling on technical courses.
Shimano GRX810 components make up the drivetrain and the rear derailleur includes chain stabilising Shadow technology for shifting security and less chance of chain slap or drop over rough ground. Hydraulic disc brakes ensure powerful and consistent braking in all conditions. Velomann VR30 wheels fitted with Vittoria Terreno Mix 33c tyres bring traction, fast rolling and excellent puncture protection, and can be set up tubeless if preferred.
