My bike has a SRAM X9 mid cage rear derailleur on it. I was thinking about upgrading to an X.0. I was wondering if it is worth the dough to upgrade and if i do, if i should stay with a mid cage model. The cassette is a 11-34t. Does a long cage model afford me more gear combinations? Will it fit in place of a mid? Will a long cage take the same chain?
I saw a post here on long cage/ mid cage, but it was out of date and was interested in later info with these newer derailleurs.
