ohhh boy, it's going to be a loooong day.
Checked the chain for stiff links, damaged cogs, derailleur adjustments... everything seems fine on the workstand... however, when I went out on a test ride I'm skipping the chain on 2 or 3 cogs, it doesn't jump from one to the other, it just skips as if it was missing teeth.
maybe it's just nerves
