I bought my commuter bike back in October. Last weekend I finally had a chance to do some more work on it. I lubed the chain for the first time. Wow, the bike is nice and quiet now. It is a fixed gear but used to sound like it had a derailleur in the rear. It is nice and smooth now.
I fixed a pedal, tightened the seat and adjusted the rear axle since it had some play in it. It took a while to get the chain and wheel tightened just right after that. It felt good to do all that. Then Monday morning I went to head to work and the rear tire was flat. So much for the “preventative maintenance” concept.
