To deliver maximum power to the pedal, you must have your seat in a raised position. Many bikers compromise their seat height for more technical riding. With Gravity Dropper, there is no compromise. Seat high for power and climbing and seat low for descending. • Buy now at http://www.chainreactioncycles.com/gr...
