Ride stability is priority number one in a mountain biking pack, and it’s the driving force behind Shift RS suspension. Unique in its category, Shift RS offers customizable load management via a vertically adjustable stability belt, which lets the rider move the belt higher or lower to better compensate for body position. Matrix ventilated foam throughout the backpanel and harness provide exceptional airflow and evaporative cooling, making Shift RS the most comfortable suspension design in the world of two wheels.
