The Solum series is your do it all two wheeled Swiss Army Knife. Equally at home on smooth pavement as it is on fire roads, Solum lets you choose your own path. Combining many of the attributes found on Sport Hybrids such as disc brakes and Rider-Optimized Geometry, Solum adds a front suspension fork that smooths out the bumps on rough terrain and is equipped with a hydraulic lock out that allows you to maximize pedaling efficiency while on smoother commuting surfaces. Should I buy a bike with Suspension? Or no suspension? Why choose? with Solum you get both.
