Bianchi Zolder Pro GRX 600 Disc Cyclocross Bike 2021
With three World Championship titles to its name, the Bianchi Zolder Pro GRX 600 Disc Cyclocross Bike is built for the rigours of performance cyclocross racing. With dedicated cyclocross geometry, the Zolder Pro is designed for out-and-out speed on the course, providing razor-sharp handling on all terrain. Specific cyclocross features ensure this frame stands out from the crowd, including a raised bottom bracket for improved clearance and revised cage placement to make shouldering the bike easier. Although lightweight, the carbon construction is strong enough to last seasons of racing abuse.
Named after the undulating Belgian CX course of Zolder, it is more than up to task when faced with ruts, obstacles and steeps. An all-new fork design permits use of up to 40mm wide tyres, with the renowned 33mm Vittoria Terreno Mix TNT coming as standard. Front and rear thru-axles offer unparalleled stiffness, further adding to the Zolder’s precision.
The Shimano GRX600 groupset is built for purpose, featuring enhanced ergonomics and powerful hydraulic disc brakes for impressive wet-weather performance. The low profile of the RX600 Shadow+ derailleur tucks it out of harm's way and the clutch silences unwanted chain slap for a silent ride. This excellent specification is rounded off with Vision Team 30 Disc wheels for durable, lasting performance.
