I brought my bike here- it's a nice little mom and pop operation that reminds me of a cross between wheel and sproket and a treehouse. The people were cool and friendly, and there was this huge dog laying on the floor (I liked that, too. Puppies!). It was really cheap work (not cheaply done- but cheap to pay for good work). Go there if you're in the south loop (or elsewhere, I guess) for some good quality work on the old two wheeler.
