This is a good lesson for everybody. You know, problems never seem to be where you first think.

Recently I was on a ride with a guy who had a maddening clicking sound from his BB with each revolution of the crank. I tightened the BB (not a fun rode-side project with simple tools). Still, the problem existed. Come to find out, it was the bolts of his front sprocket banging into the mounting of his kick-stand. I took the kick stand off and problem was solved, "You won't be needing this anymore, Bud. Heave HO!!"

This week I had a strange sound coming from what appeared to be my front brake rubbing against my rim. The rim was true and brakes calibrated correctly. What the heck?! I checked and checked and adjusted. It drove me nuts. Sure enough, it was problems from the REAR brake.

That is the art of being a good bike mechanic. Anybody can do the maintanance. The bike mechanic artisto can isolate and fix problems fast.
