Sometimes the little tools save you a lot of time. I got this tool for my birthday this week.
It measures the amount of wear on your chain, and indicates .75% and .1% wear - which is generally when you should replace a chain. I usually try to replace the chain after 1,000 miles, but this is more accurate than waiting for the chain to slip, or doing the 'how much light shows between the chain and the cogs in the chainring ?' approach.
Park and Spin Doctor have their own versions. The Spin Doctor model is around $4.00. Next to a pedal wrench, I think these are the most useful of the very very specialized bike tools that I have.

Great Idea! Thanks for sharing - I would have never known about this if it was not on the web.
