Wow- I honestly cannot believe what happened to me at this place. I purchased 2 bikes and 2 locks about 3 weeks earlier, and the gentleman who helped me then was great. About 2 weeks later, one of the tumblers in the lock fell apart. I took the lock back in, with the receipt, and the owner (?) basically said that the lock must have been tampered with, and he wouldn't let me exchange a $20 lock after spending over $800.....really? He was basically calling me a liar, and when I tried to explain that it would be good customer service to exchange the crappy lock, he stepped up really close in my face, and said "don't tell me about customer service!" Wow! Obviously someone needs to tell him because he hasn't got a clue. He could not have handled the situation worse than he did. There are so many great bike shops in Phoenix that thankfully I will never have to support those thugs ever again. I would suggest that, unless you like buying defective merchandise with no exchanges allowed, to avoid this place and support local establishments who actually care about their customers.
