Useless and Worthless Tools
A couple of current threads got me thinking about tools that I think are inadequate, a waste of money, something I would never use, etc. For example, I've never bought a handlebar holder; the thing that keeps the front end of the bike from swinging when the bike is in a repair stand. The few times I tried one, it annoyed me more that the bars were immobile. Until I became a total tool geek, I'd never buy the "fake pedal" thingie either ... the thing you screw into the right crankarm for when you're building up a bike. Why not just screw in a pedal? Waste of money to look more "pro."
What tool do you never see yourself buying? What tools have you bought that you ended up regretting?
