I’ll have a think mate. I may need it to make up the missing one from my m951 shifters. I stupidly have misplaced the other adjuster but it will be in box somewhere. I have caved in though and bought a pair of m952 9 speeds along with a matching XTR 9 speed cassette.If you cave and end up buying a set I'm in the market for just a left-hand one!! Need the barrel adjusters and cable head plate cover.
