Norco Storm 4 2021

The Storm 4 picks up where road, gravel, and hybrid bikes can’t go fatter tires, off-road-oriented progressive design, and features that’ll give you the chance to explore what mountain biking is all about. With a comfortable, capable off-road design, the 6061 aluminum frame is off-road worthy, and capable of leading a double life on city streets and park paths. Designed with our holistic approach to fit and geometry, the Storm 4’s longer reach, slacker head tube angle and steep seat tube angle provides more powerful, efficient pedaling, increased climbing traction and added grip and control when descending. Complementing its 100mm of SR Suntour XCE28 fork travel is a solid, reliable Shimano Altus/Tourney 21 speed drivetrain, so you can always find the right gear and spend less time at the shop. The Tektro hydraulic disc brakes provide controllable power for confident, safe stops on and off of the road.
