    36t 9 Speed Cassette with 8 Speed Derailer

    I recently switchted from 8 speed rear to 9 speed rear. Im using a Deore 9 speed shifter with a 12-36 9 speed cassette. However I am still using an 8 speed XT rear derailer.

    I problem I am having is that I cannot seem to adjust the B tension screw enough to get the derailer jockey pulleys from being too close to the 36t cog.

    Am I forced to buy a new rear derailer?

    There are several things you can do. I ran into this problem using a 34 tooth cog on a 7 gear setup. Some people will put the screw in the other side this makes it a bit longer. This is a standard size screw you can get in ace hardware buy the stainless. You can put a washer between the derailer and the hanger an axle washer will work. The largest cog a Shimano derailer will climb depends on how far away from the dropout it is. You can pull the derailer back I tied the cable to the fender strut. I saw one guy use a spring connected to the rear rack. A Shimano megarange derailer will climb a 40 or a 48 tooth cog depending on the model and they are only $12. They have a lot of play so use a spoke protector. DSC02620 | Flickr - Photo Sharing!

    Good idea on the washer, I would have never thought of that!
