Never been to Race Pace, but Ive been to several Performance shops. I find performance good when I need something that other shops dont carry. Ive always had good luck with finding odd sized, or old vintage random things, or need something in a pinch, etc. I wouldnt ever buy a bike from them, or trust them for any service(or any shop for that matter), but if you need tubes, or something like that I think they are fine. Im with the other poster, they are staffed by folks that need jobs. I cant comment on Race Pace, but have heard good things about them.
