First bike shop, okay.
But the second? I mean... Three days to swap a pulley wheel that is, I kid you not, a 3 minute job.
3 minutes vs. 3 days.
It's why I don't go to bike shops (plus the exorbitant fees).
Even more seriously. In the time it takes you to type in youtube, figure out a video to watch, and swap out the pulley, you probably wouldn't even have made it 1/2 way to the bike shop to pick up your bike three days later.
