Chain lenght
I know I have read it here someplace, but can't seem to find how to calculate the correct chain length you need when replacing a chain and chain sprockets. I did a search but couldn't find what I was looking for. Memory fading 
. Well thats not all but you get the point.

From Sheldon:
The best technique for setting chain length is to thread the chain onto the large/large combination, without running it through the rear derailer. Mesh the two ends on to the large chainwheel so that they could be connected (outer link meets inner link), then make the chain one complete link (one inch) longer than that. In almost all cases, this will give the optimum length.

^^^^^ Remember when one talks about "one complete link" this is in fact does look like two links.

Big big plus two works great, but if you are replacing a chain just match the new up to the old (accounting for elongation of course).
