Hi - I have the opportunity to get an 11-32 8-speed cassette *free* to replace my 12-26. My rear derailleur is a Sora 3300, and Shimano has removed all references to it on its website. And no other search has turned up an answer to the question of whether or not this derailleur's tooth limit is compatible with the 11-32 or not. I'm guessing no, because it's a 7-8 speed derailleur, but I wanted to check. I live in a VERY hilly area - thus the wish for the other cassette. Any advice is very appreciated! Thanks!
