SRAM 5.0 RD vs XTR M960

[Bernard Rother]

Hi there, just a quick, but important question. I'm entered in a ride on
Saturday ...... damaged rear derailleur jockey wheels in fall last Sunday
and cannot locate replacement parts on South Africa. LBS suggested XTR. They
have a Long Cage and Super Long Cage RD.
My cassette is an SRAM 9.0 9 speed with 34T and a SRAM Gripshift. Will one
of the XTR RD's be compatible with the other SRAM parts. I have max 2 days
to let the dealer know in order to organise postage etc.

Really need your help here .... thanks.

Unless the shifters are SRAM ESP, which use 2:1 for Shimano compatibility.

While the XTR is a hell of a lot better than a 5.0 mech, it's not gonna work
with a SRAM gripshifter (unless it's a special one, I think called ESP,
designed for shifting Shimano parts...but if it were, you wouldn't be using
that 5.0 now, would you).

If you cannot get a SRAM rear, get a Shimano rear shifter to go along with
that XTR derailleur.

ESP is the 1:1 ratio. You can get Shimano-compatible SRAM shifters, but
then they won't work with a SRAM rear mech. Because this guy's using
SRAM shifters and mech, then it must be ESP (1:1), so an XTR rear mech
won't work.

Oh yeah. I see that clearly now.

I'm ill, OK? That's my excuse and I'm sticking to it.

Thanks for all the feedback iro the above. We tried the XT mech with the
SRAM 5.0 shifter, 1st & 2nd shift was ok but skipped every second cog
thereafter ..... as suggested in the replies.
I came home with a shiny new XT mech and a pair of LX rapidfire shifters.
Had to leave behind the XTR and use the funds on the shifters ;-(

Have just finished installing the whole lot and come back from a short ride
..... what a pleasure !! The old SRAM 5.0's worked flawlessly until the
spares dried up but this Shimano kit is like a hot knife through butter ....
sooooo smooth. Now the sad part, the weather prediction for Saturday's ride
is 40% rain, strong westerly wind, 3 deg C temp with snow .... darn.

Thanks again for the help.
