Jump on GT's Karakoram 4.0 and experience the smooth, fast ride of a 29er for yourself. It boasts GT's light, reliable 6061-aluminum frame for easy pedaling and nimble handling, while the bump-busting SR SunTour suspension fork with 100mm of travel provides control on rough trails. You also get dependable aluminum wheels with knobby Maxxis tires, a slick-shifting 24-speed Shimano drivetrain so you can cruise over the climbs and grippy linear-pull brakes for the flight back down.
