In 2007, the Riot roost deflector became the first proprietary ID product for Shift and has received a shoulder upgrade since. Roost deflectors protect riders against rocks flying off the back tire of bikes ahead. Beyond that it simply needs to disappear to the rider. To that end, Riot offers fit adjustment at the front and back of the shoulder straps and adjustable elastic waist straps. Pivoting shoulders and living hinges at the back provide articulation.
