Nice! I'm actually going to be doing the same thing in a weekend or two for all my friends. Luckily enough, most of them ride bikes all summer long and if it's still warm. However, most of them also don't know how to tune up a bike so instead of them all going down to ****ty bike shops and getting charged up the arse, I'm doing it all for free on one of these glorious afternoons. Hopefully the weather holds up here in Chicago for a little bit.

Props.
