There is a strong fixed/track following in Tempe, mainly students who do the affordable fixed conversion. But if your talking true track riders/racers, its vague. I know, because Im one of em. Im 22, and when I lived closer to ASU I submitted to the crazy alley cats that only involved the most dangerous of routes, especially since none of us were seen in public with brakes haha. At our bigger races, of course sanctioned underground for its dangerous mishaps, we easily had 40-50 people show from all over. Places with a velodrome close, like san diego or colorado springs, much more contacts!
