Overview
About this bike
It's the Bianchi pedigree as being a world-class racing brand that makes every day on the trails aboard the Duel a blast. Its lightweight aluminum frame, category-leading Shimano hydraulic disc brakes, and sporty geometry will take your trail riding to the next level. Also included is a Shimano 18-speed drivetrain for the best possible range of hill-climbing gears and a supple hydraulic suspension fork. The Duel also has rear rack bosses for those camping adventures done in-between the afternoons of riding with the family on the gravel railroad towpath. If a wolf in sheep's clothing is your idea of your next bike's personality, the Duel fits that character!
