Introduction to the Vibration Absorbing FSA VAS Stem

Full Speed Ahead’s VAS Stem for Gravel Bikes

The Full Speed Ahead VAS Stem for gravel bikes was recently launched at Unbound Gravel in June. 

The FSA VAS Stem was in development since 2019 with its roots and DNA being born out of the Flint Roads of Emporia, Kansas, where the VAS (Vibration Absorbing Stem) stem was tested to gather real world gravel conditions in one of the most demanding events for gravel riding. Taking that valuable feedback to FSA’s design offices, FSA built a stem that actually can help riders save energy, smooth out gravel and terra firma conditions that they encounter.
