Bianchi Duel 29S Alivio Mountain Bike 2021
At the heart of the Bianchi Duel 29S Alivio Mountain Bike is its high-quality aluminium frame that is light and robust to elicit a lively, energised ride over a full scope of trails and tracks. The SR Suntour XCM suspension fork partners the frame perfectly, adding comfort and control over rough terrain thanks to its plush 100mm of travel. The balanced geometry affords a stable riding position, increasing the rider’s confidence when the going is fast and technical.
The strong 29” wheels can manage even the biggest hits and pair with the grippy Kenda 2.2” wide tyres to afford traction under acceleration and while cornering at speed. A Shimano double chainring, 9-speed gear configuration offers a vast range of ratios, and hydraulic disc brakes stop with power and accuracy no matter the trail conditions.
