    Chain tension / MRP question

    I'm thinking of changing my rear derailleur over to a short cage derailleur to get better clearance and keep it out of the way. My question is.... if I do this, how much is it going to mess w/ my chain tension w/ my MRP?

    I am pretty sure you will need a road cassete to match up with it

    I think that the Ultegra 9sp matches up, but I'm not positive.

    I think that the Ultegra 9sp matches fine w/ my cassette, but I'm not positive.

    Okay, really, I'm curious. Will it f*ck w/ the bottom tension roller of my MRP? Like will it be semi useless?

    From MRP

    When you buy your short cage it lists the cog capacity. Just be sure your cog set is no larger than what the derailliur is designed to work with. Shimano shorts cages fit 29 teeth. This will not affect your MRP at all. You may want to shorten your chain if your reducing teeth but insure you have enough chain length so if you bottom out (full Susp) your derailliur isn't being pulled too tight. ie breaking your chain, derailliur or ripping off your lower pulley on your MRP guide.
    Cheers
