short cage vs long cage deraileur
i don't see any benefits to a long cage, am i missing something?
What's "social pace?"
you don't see benefits? do you have a good working understanding of derailleur capacity?
the short cage rd's are not more widely used because of their limited capacity. i'm going to run a short cage on my 1x9 but i don't believe you can use it on a 3x9 with a standard cassette (possibly with a road one, i havent done the math).
There is a great sticky thread on this topic in this forum.
