I hate the Quadra. If it's old, it's useless. I'm in the middle of trying to resurrect one right now. The elastomers have turned into a crumbling mess. I'm trying to scrape them out form the inside of the tubes. I lied, I've given up on trying to fix it. I think the legs are steel, becuase it's the heaviest XC fork I've ever felt. I love the Indy though.
