So who is the instructor?
That is a pretty basic class. On the other hand, with only 8 students a really good instructor will be able to match the content to each student. I've messed with bikes for a pretty long time and I've wrenched in bike shops for around a decade. I'm still constantly learning new stuff even regarding the basics. If I thought the instructor was a really good guy I'd sign up in a heartbeat.
Really good instructor - worth it beyond a doubt. Average instructor - maybe not.
