Chains and Sprockets

[flynrider]

The marks are probably good enough, and honestly thats what I use, some some people are more anal than that and want it to be precise. The tape is one way to be precise..sort of lol

I use the marks as a starting point, then sight down the chain with the chain guard removed for fine adjustment.

For reinstalling the wheel, I am also from the "foot" school of thought. A wedged 2x4 would probably work better, but that would mean I'd have to either make one, then remember where it is when I need it. My foot is always handy (footie?).
