Whatever the trail has in store, the Cannondale Cujo 2 27.5 in. plus bike takes it all in stride. With huge 27.5+ tires and stable, confident geometry, it handles the rockiest, nastiest terrain.

  • Features

    • With big, grippy tires, stable geometry and a lightweight Cannondale frame, the Cujo just makes mountain biking easier
    • 27.5+ wheels combine wide rims with big 2.8 in. tires for unreal traction and cushiony float on just about any surface the trail can throw your way
    • Trail-focused geometry delivers a stable, confident feel that encourages you to let 'er rip
    • A tapered head tube, 110x15mm thru-axle front hub and Boost QR rear hub all contribute to Cujo's solid feel and precise handling
    • Light, simple 1x drivetrain and hydro discs; wide-range 11-42 cassettes and 30t rings give you a rock-crawling low gear
    • Wide bars and grippy WTB Ranger tires offer control
    • Specs and images are subject to change
