I dont want to step on any toes but i perfer the bike factory(kakaako) for parts. The guys in there are decent to me and my friends. McCully bike shop for tires, tubes, and misc consumables. I don't go to island triathlon and bike unless i have too. The bike shop on king st is expensive. BOCA hawaii is a shop right down the road from bike factor, they have alot of used parts and great training advice. I organize events for the aloha single speeders fixed gear group. Glad to have another rider in hawaii. aloha
