Hi, i just picked up a 'long cage' rear mech. I was thinking it would be marked 'SGS', but when it arrived its marked as RD-m972 'GJ'. I can't seem to find any info on it, so what does this GJ stand for, anyone know?
Update- just measured the distance between the pulley bolts and its 80mm so would that make it a medium cage and a 'GS' in shimano talk? Still weird it stamped as GJ.
