Dual Sport 3 is a high-performance hybrid bike with upgraded components that stand up to long rides on a variety of surfaces, from city streets to gravel trails and more! Plus, front suspension, a wide-range 1x drivetrain, tubeless-ready rims, and puncture-resistant tires give you the confidence to take on bigger adventures.
It's right for you if...
You want to up the adventure level on your recreational rides, and want a fast and rugged hybrid bike with quality parts that will withstand daily commutes, fitness rides on light trails, rail trail tours, and more.
The tech you get
A lightweight aluminum frame, a suspension fork with a lockout feature, and a simple 1x10 Shimano drivetrain that ditches the front derailleur for easier operation. Don't worry, the wide-range 11-46 cassette still gives you all the gears you need to conquer hills and crush flats. Shimano hydraulic disc brakes, tubeless-ready rims, puncture-resistant all-terrain tires, ergonomic grips, and a Blendr stem for easy accessory integration.
The final word
Dual Sport 3 is fast and efficient on pavement and confident and capable on dirt trails. It has upgrades on the parts that make the biggest difference in performance, like the simpler, lighter-weight Shimano 1x drivetrain, tubeless-ready rims, and puncture-resistant tires.

Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
