I've had my new hybrid bike for a month, and I assembled it myself. Apparently one pedal was not screwed tight enough, it fell off while I was riding and the screw got a bit stripped at the rim. I took it to LBS and the guy asked for $40 for a new pedal and and extra $65 for tuning it up. I thought it was very expensive so I came back and was able to screw the old pedal back on.
Now I'm worried that I should doublecheck some of the parts and tune the bike up more carefully. Could you guys give me some tips on how to tune up a new bike? Is it OK to tune the bike up yourself or is it necessary to go to an LBS for tune up?
