The class is great so far.
They provide all the tools and you use your own bike. Today was the basics. Tube and chain repair and replace. Shifter and derailleur replacement and adjustments. Brakes (mechanical and hydraulic and disc). New cable install and troubleshooting.
Tomorrow we take apart the crankset and learn how to fix spokes and do wheel truing. For $210 it's well worth it. I've learned more about my bike in one day than I have in years of riding and fiddling in the garage.
I think I lucked out as there are 4 of us in the class. It can be up to 10 people. So the instructor was able to give each of us more attention. 2 road bikes (rim brakes), 1 road disc (me) and one mountain bike (rim), who was the new bike security lead at the U of C.
I've also discovered how crappy I've been treating my bike. The day starts with some basic cleaning skills. As dumb as that sounds, you find out how dirty your bike really gets and how you really should be taking care of it.
Also, 20% off all parts and tools for participants means they get a little more of my money tomorrow.
