When progression is the name of your game, the Co-op Cycles DRT 3.3 bike is your full-sus friend, with wide trail tires that prioritize rollover while giving you enough width for traction and cushion.

  • Features

    • Air-sprung RockShox Revelation RC front suspension and RockShox Deluxe Select rear both have external rebound adjust to keep the ride smooth and wheels glued to the trail
    • Wide trail tires provide better rollover than plus-size tires; XS, S bikes have 27.5 x 2.4 in. wheels and 120 mm of travel; M–XL have 29 x 2.4 in. wheels and 130 mm of travel
    • 1 x 12-speed drivetrain with Shimano SLX rear derailleur eliminates the front derailleur to enable swift, streamlined shifting and reduce overall weight
    • Shimano SLX 12-speed rear derailleur decreases chain slap and makes shifts more reliable
    • Comes outfitted with a remote-control X-Fusion Manic dropper seatpost to let you adjust to terrain on the fly (XS–M frames allow 100 mm of travel; L, XL frames allow 150 mm)
    • Shimano hydraulic disc brakes deliver reliable stopping power on- or off-road and in variable weather conditions
    • Wheels and tires are ready for tubeless setup
    • Front and rear thru axles provide added rigidity
    • Bicycle weight limit is 300 lbs. total, including rider plus all gear carried on the bike and on the rider's body
    • Pedals not included; specs and images are subject to change
