Bicycle Repair

Bicycle's are amoung the worlds most elegant tools, and fun and good for you too.   That said, they do require some upkeep, but their simplicity (compared to a car) is part of their awesomeness.  Most anyone can learn the basics on bike repair, and most of it's not too hard.  Lifehacker had a good link today I hadn't seen before, and there were a couple cool suggestions in the comment section.

These sites all have great hints and tutorials for fixing or tuning bikes.
