With revamped geometry and improved suspension kinematics, the Sommet is ready to tackle the roughest trails there are, from big mountain alpine descents to steep technical enduro trails. Improved Suspension Leverage Curve and Sensitivity Vitus has straightened this frame’s leverage curve and increased the progressivity to improve the small bump sensitivity and mid-stroke support to keep you in control when the trails get rough. Along with improved geometry, the new Sommet also has more seat post insertion which allows for a longer dropper post to be fitted. Basically, Sommet is better in every way. If you want a confidence-inspiring Enduro frame that will help guide you down the roughest trails then the Sommet is for you.
