There Is An Airscoop Behind The Seat That Sends Fresh Air To The Rubberband. Most People Install A Filter There So There Won't Be As Much Dirt To Shorten The Lifespan Of Said Rubberband. Rubberbands Ain't Cheap. I Will Try To Take A Pic Tonight & Post It Tommorrow For Your Approval. Ha Ha Ha.
DD, be carefull with this air inteake and putting a air filter on it, on our Tecate ride 4 Rhinos had there Rubberband go poof no more rideing, and had no extra one, it seem that the Rubberband did not get the cool air it needed ;-)
