Hi all, I checked my dropout as per a similar method as Mark S had replied with. I found that to be all OK, I thought it would be, with the SR RD that I took of gave no faults. So now I am guessing that the SR I have fitted is out of alignment. I had replaced all the pully cages with NOS items, and that had made no improvement. I will now make a alignment checking tool for the SR RD, this will at least tell me for certain that this is the problem, and also how much out it is........regards wayne davidson Invers NZ.......

I tapped a piece of heavy wall tubing to 10mmx 1mm, to accept one end of
the axle. I threaded on a track nut, backwards, and put on two large,
thick
washers and threaded it into the tubing. I'd have just enough axle
protruding so that if I placed a washer on either side of one tip, the
other end of the axle didn't quite reach the other tip. Slide the axle
all
the way into the back of the slot, and tighten the nut. See

You should use an axle, threaded rod, AKA AllThread, isn't usually straight enough.
The same tool can be used to align derailleur hangers. Just install a 2nd
axle in the tips. and thread the tool into the hanger threads with the
axle
protruding to the left and the tubing to the right. See
