Introducing the Turbine Dropper Post: A patented hybrid design that couples mechanical and hydraulic locking technologies, inspired by MTB disc brakes. The rider's body weight is supported with a mechanical lock; meaning a solid connection and less potential for failure over time. Lower air pressures and static seals offer unrivaled performance, control, and reliability. Turbine also operates in below-freezing temperatures making it perfect for Fat Bikes and cold weather riding. Less down time for service equals more saddle time on the trails.
