    9 speed to 10 speed conversion

    currently using 9-sp x.o shifters, 9-speed cassette, 9-speed x.9 rear derailleur. i want to convert the bike to a 10 speed, have x.9 10-speed shifters, 10 speed chain, 10-speed cassette. do i need to get a 10-speed rear derailluer as well or will my 9-speed x.9 rear derailleur do the trick?

    You'll need a new 10 spd rear dérailleur because the pull ratio
    is different from 9 to 10 spd..

    I plug in the topic

    So, if someone had already used 10speed?
    The most I'm interested in action 3x9 cranks shimano chain, **** on the 10th

    Shimano claims that this solution will not work, and I think it will be and that is good.
    Maybe someone already used? Do you have someone so rides
    I just think about the crank 3x9.

    figured that might be the case...but thought the "exact actuation" of the 10-sp derailleur might be the same as the "1:1" actuation of the 9-sp derailleur.

    1:1 with 10 speed is different.

    but I am concerned about the cranks. Will it work on the crank SLX (9 speed) chains of 10 speed?
    I have a new SLX crank (9speed), and I have everything components for 10 speed. I don't want to mount them if the crank will perform poorly.

    sorry for the English, as you see I'm Polish so I'm learning all the time

    9 speed chains are wider (6.6mm) and will tend to rub against the closer spaced
    10 speed cassette cogs....a 10 speed chain averages 5.88mm and will work on
    your SLX chainrings...I've been running 10 speed chains on my 9 speed systems
    for years without issue...

    On the back, I know. And in the front? So there should be no problem as I cranksets for 9 with a chain of 10?
    Exactly how you drive?
    In Poland, no one has yet posted on a forum this configuration?

    Does it work?

    Crankset SLX (9speed) 44/32/22 !!!!!!!!!!!!!!!!!
    chainrings hg-74, 94 or sram 10xx
    slc cassette hg-81 10 speed
    rear, the front derailleur X.7 10 speed
    SRAM X.7 trigger 3x10

    YES
    thats very interesting...awesome gold chain by the way. i hear they also come in red

    i've already ordered an x.9 10-speed rear derailluer but i gonna try it with the x.9 9-speed rear derailleur just for giggles.

    keeping the 9-speed front derailluer and 9-speed cranks/chainrings (had a 2x9 setup..go to 2x10). was going to install the 10-speed x.9 front shifter with the x.9 10-speed rear shifter. i think i'll be ok with the 10-speed front shifter and 9-speed front derailleur.

    Jake_pay,
    does it get tough to climb using your current setup 32t cog with 42-28 crankset.
    I am actually keen to get a XG999 with a 26-39 cassette but I thought I would be hard to climb hills.

    Gracias.

    On another note,
    can anyone clarify why a 9spd rear derailleur would not work with a 10spd cassette ?(except on a 36t cassette)
    My point is that what defines the pull ratio is the shifter and not the derailleur. Unfortunately, I do not have a 10spd shifter and cassette to try this out but I would be happy for someone to give me the right answer.

    Thanks!

    For my average rides the 11x32 cassette with the 28t ring works fine..

    On the areas that I ride on occasion, were the climbs are steeper and longer..
    I'll run an 11x34t instead of the 11x32

    the SRAM specs on the x.9 -sp rear derailluer state 34t cog max...although messing with the B-screw might accomodate a 36t cog. i'm gonna try it before i put on the new x.9 10sp derailleur to test it out. should arrive next week. i figured the same as you regarding the "pull-ratio" unless the sweep is different...we'll see next week.

    finshed the up grade, x.9 2x10 rear D, x.0 2x10 front D, x.9 2x10 shifters, 10-sp chain, 10-sp cassette. the 9-speed rear D worked but not as well as i would like. better to so the full upgrade. 2-sp front D doesn;t pull over enough with the 2x10 shifter...maybe if i left the old front shifter. disappointing the have the SRAM x.9 2x10 front shifter brake within the first 6 shifts while still on the bike stand. seems there may be a problem with the SARM x.7 and x.9 2x10 front shifters. mine was replaced promptly...still, gives one pause....gotta says though that the glide tech is very smooth.
