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. The Storm offers quality, performance and accessibility to a wide array of riders, and is the perfect chance to give you the time and versatility to learn what kind of mountain biking is perfect for you. The capable off-road design, with its lightweight 6061 aluminum frame can easily lead a double life on city streets and park paths. Designed with Norco’s 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, added grip and control when descending. Complementing its 100mm travel SR Suntour fork is a reliable Shimano Altus/Tourney 21 speed drivetrain, while the Tektro hydraulic disc brakes provide all conditions stopping power.
