Bianchi Duel 29S Alivio Mountain Bike 2021
Designed to be your gateway into the world of mountain biking, the Bianchi Duel 29S Alivio Mountain Bike helps you take your first steps on the trail in total confidence. Perfect for gravel, fire roads and trail centres, it features a 9-speed Shimano Alivio drivetrain to tackle steep climbs, and hydraulic Shimano disc brakes for powerful stopping in all conditions. Bianchi’s Sport geometry is comfortable and efficient on a range of surfaces, and the 29" wheels hold speed to easily roll over technical terrain.
The SR Suntour XCM HLO DS fork provides 100mm of supple suspension travel, ideal for smoothing out roots and ruts on the trail. To improve efficiency on longer climbs, it features a hydraulic lockout system to provide a firm pedalling platform, reducing energy-sapping pedal-bob. With impressive cornering traction, the Kenda Booster 2.2" tyres are an excellent choice for all-season riding.
