Hey, I've got an 08 Giant Glory 0 that i'm running as a DH bike. Boxxer up front and a crappy Manitou 4x in the back. I want a new Vivid, but need the exact ratio and size for the bike. Called up Giant CS and they were no help and it doesn't say on their official website in the archived section either. I don't just want to get a shock and hope for the best, much thanks!!
