estrella mtn cyclery notwithstanding (it is pretty far away), for sheer convenience there's rage on scottsdale road at about oak street and tribe multisport on scottsdale road and mcdowell (hidden in behind the new post office). but i prefer for myself landis in tempe at southern and 101 or domenics on rural at about broadway. if i were buying a bike i'd go see denise at estrella. if i'm buying expendables like tubes/CO2 cartridges/gu i go to performance or rei just for the price. for maintenance and components i go to domenics or landis. if you are totally mountain go to rage. if you are totally road go to tribe. any questions just pm me. hope this helps.
