text: I twisted the valve off my front tire this past weekend. It was quite a frustrating event. But it gave me the perfect excuse the check out PHX Bike: replacement inner tube! Dudeman behind the counter wasn't especially friendly, but that could have been because I went to a bike shop and asked if they carried inner tubes. Derp, I get it, But they aren't on display and I'm a visual person. Anyway, I showed him the size of tube I needed (I cut it out of the deflated one) and he says \"Eight bucks\". Okay, I need it. And thank you very much.\n\nOn the plus side, \"service\" was fast and I'm supporting local business. I could have gotten this is for about $5 online, so I don't think this place's mark-up is outrageous. I would like to have given an higher rating. It's just I felt like asking an ex to change a tire, like I was more of a tired burden than a potential loyal customer.
