Ok I've got to buy a new fork for my bike its a 2005 Jamis Exile. I bought a 2010 Marzocchi Dirt Jumper 2 Fork. My question is im going from a 80mm to a 100mm. Also since the bike is a XC bike i was thinking this would be a good fork since I am a heavy weighted rider.... Literally I'm 285 so i was thinking since these forks are meant to take a beating they should be good since i ride not only trails but also urban stuff around the local campus with decent drops and bumps stairs etc.... What do you think?
