Built to raise your game and ignite a passion for the dirt, the Cannondale Trail 5.5 thrives on low-impact trails and gravel roads and delivers the handling and durability to get after it.

  • Features

    • Simple yet sophisticated SmartForm C3 Alloy aluminum frame yields a light, lively frame that's durable enough to handle whatever the trail throws your way
    • SAVE micro-suspension—strategically engineered flex zones built into the frame's rear triangle—delivers a smoother, more controlled ride
    • A slack 68º head angle creates exceptionally stable handling so you can charge the descents with confidence
    • SR Suntour XCM coil suspension fork features 100mm of responsive travel; remote lockout lets you easily switch it off/on as you transition between climbs and descents
    • 2 x 10-speed shifting with time-tested Shimano Deore shifters and derailleurs provides smooth, precise shifting; Shimano hydraulic disc brakes offer stopping power and control
    • Shift and dropper cables route cleanly through the StraightShot window in down tube for an integrated look and easy maintenance; rear brake line is secured outside the frame
    • Compatible with 31.6mm internally routed dropper posts (not included)
    • Specs and images are subject to change
