A 29er trail bike with its priorities straight, the Cannondale Habit 4 AL bike has a progressive design that delivers playful agility and serious capability—all in the name of fun.

  • Features

    • From weekslong backcountry adventures with friends to solo singletrack jams after work, the Habit 4 delivers performance and fun for every rider
    • The head angle is slack, the stays are short and the seat angle is steep: This long, low modern geometry helps you wring a little more flow out of every kind of trail
    • Since riders come in all sizes, Proportional Response design tailors the suspension layout by size so every rider gets optimal traction, suppleness and control
    • The suspension linkage arrangement for each size is tailored so each rider gets suspension performance while braking and improved overall pedaling efficiency
    • Asymmetric Integration allows the Habit to have 435mm chainstays that are nimble and capable in corners while still having loads of tire clearance and stiffness
    • 29 in. wheels, grippy tires, wide bar, short stem, powerful brakes and a dropper post deliver straightforward performance
    • Included Cannondale DownLow dropper seatpost with internal routing is an infinitely adjustable, easily serviceable, air/hydraulic unit with a sweet cable remote
    • DirectLine cable routing means no rattle and no fishing around for cables
    • Ai Offset Drivetrain opens up the rear triangle for more tire clearance, while keeping chainstays short for nimble handling
    • Post-mount brakes; frame is compatible with ISCG05-standard chain guides (not included)
    • Pedals sold separately; specs and images are subject to change
