We rode our bikes up to the 10 and Van Dyke shopping center, and my handlebars had slipped into a very uncomfortable position. We dropped by Aco to get some hex keys, and they were very reasonably priced. They were even very nice about the fact that we bought standard and needed metric, and made the exchange quickly for us. They do need to get a better line system though, people were just kind of milling around the registers. But it's much faster to go here than a big box store like Lowes if all you need is something small.
