After reading some of the previous posts of the long cage vs. short cage debates I'm still a bit confused. I have a double front crank (48-38T) and a 12-27 rear cassette. It looks like I have a 25-tooth chain-wrap capacity (48-38=10, 27-12=15, 10+15=25). When I view the shimano spec sheets should I be looking at the "Total Capacity" for if I need a short or long cage derailleur? It looks like a short cage should be fine from previous posts.
I've added a link to one my previous posts if it helps:
