Looking for adventure? 3 Series mountain bikes stand ready to get out and get going. The 3900 Disc is perfect for light off-road use, and can handle the rigor of gravel paths, dirt roads, and woodsy trails. The 3900 Disc is everything the 3900 is, but with greater stopping power by way of the cable-actuated disc brakes. Disc brakes are recommended for users experiencing adverse weather conditions and/or greater speeds.
