A 29er trail bike with its priorities straight, the Cannondale Habit 4 has a progressive design that delivers playful agility and serious capability—your favorite trails have never been more fun.

  • Features

    • SmartForm C1 alloy frame delivers lightweight, responsive handling and 130 mm of plush suspension controlled by a RockShox Deluxe Select+ shock
    • RockShox 35 RL Gold fork delivers 140 mm of hit- and bump-absorbing travel
    • Designed to be your daily ride, the Habit is built for easy service with durable suspension pivots, easy internal cable routing and no oddball proprietary stuff
    • SRAM SX Eagle 1 x 12-speed drivetrain offers reliable shifting across the 11–50-tooth cassette, offering a wide range of gears to take on any terrain
    • Shimano MT200 hydraulic discs provide reliable all-condition stopping power
    • Internally routed TranzX dropper post gets your seat low and out of the way for descents, and then quickly back up for climbs
    • 29 in. wheels with big, grippy tires offer a plush ride with plenty of traction
    • Progressive geometry, a properly wide handlebar and a short stem support an effective riding position, helping you get the most out of every trail
    • Proportional Response design tailors the actual suspension layout by size so that every rider gets optimal traction, suppleness and control
    • Using size-specific center-of-gravity data, the suspension is designed and optimized for each frame size
    • Ai Offset Drivetrain opens up the rear triangle for more tire clearance, while keeping the chainstays short for nimble agility; a stiffer, stronger rear wheel is just icing
    • A reversible chip lets you to tweak the geometry, raise the bottom bracket and steepen the head angle by half a degree, or switch from 29er to 27.5+ wheels
    • A rugged rubber guard adds protection around the bottom bracket, guarding the frame against debris and trail obstacles
    • Thru-axle pivot system creates a rock-solid connection between both sides of the swingarm for instantaneous response—no twist, no flex and no special tools required
    • Pedals not included
    • Specs and images are subject to change
