When adventure calls, answer with the Ozone 500 Men's Fragment 29 in 21-Speed Mountain Bike. The durable aluminum frame is complemented with a sturdy suspension system that absorbs shock and reverberation, while the all-terrain 29-inch x 2.3-inch tires supply a smooth ride. The Shimano Revo Twist shifter and Shimano derailleur make transitioning between speeds a breeze. The MTB Riser handlebars and padded seat provide comfort along the journey.
