    X5 upgrade

    Today the SRAM X5 rear derailleur fell to bits do I'm thinking of changing to X7. Does anybody know if this will work with the X5 shifter. And would I need a long med or short cage?. I don't want to spend more than I have to. Just want to be able to use my bike again. Front sprocket is 44/32/22T cassette is 11-32T. Thanks guys

    Yes, the only thing is if you have 9 speed you have to buy a 9 speed (also works with 7&8 speed as well), similarly 10 speed only works with 10 speed. Any 9-speed X3-X0 rdr will work with 9 speed X-5 shifters. Any 10-speed X-5 - X0 rdr will work with 10-speed X5.

    Cage length goes by the total teeth, in general long for 3 rings, medium for 2 rings in on the crankset. But, for an accurate measurement, subtract the total teeth on the crank and cassette. 37t and below is ok for a medium cage, anything higher you need a long cage or you will not be able to keep chain tension in all gears. An example:

    Cassette : 36-12 = 24
    Crankset: 42-22=20

    Total difference is 44 and a long cage is required.

    If you have 2 rings and a bash, the same formula applies.

    I have three rings on front. With the teeth numbers I gave above. Wanted to go with medium cage for better shifts but not sure if it could cause damage with the teeth I have.

    I recommend a long cage. You could get a medium to work, but there will be gears that the chain will be very slack and droop quite a bit as well as some gears that the chain will be very taught. You have 41t difference and a medium is good to 37t.

    I went and bought a large cage but it was much bigger than the one I removed. So I returned it. Was going to try find a medium. I can't understand why it was a smaller one in my bike if it is supposed to be long cage for the amount of teeth I'm running. Chees
