SRAM 5.0 RD vs XTR M960

Bernard Rother said:

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.

No, the XTR uses a 2:1 cable pull ratio, whereas the SRAM uses 1:1. You need a SRAM rear mech.

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

Really need your help here .... thanks.

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.
