I'm trying to upgrade my cassette for lower gearing on a Nishiki Continental. The previous owner put on a (NOS) Shimano XT rear derailleur. I use friction shifters.
I looked on the back of the cage and the models says RD-M739. The document from Shimano says 32T maximum. What do you think, would a 34T 9-speed work?
I would like to have a bigger rear cog so I'm asking just to be sure it's not a RD-M739-SGS. How can I tell? Would SGS be stamped on the back if it would be?
Update: I actually found a 7sp overdrive with a 34T largest cog on another bike that I tried. Seems to work just as fine as on the bike it came from.
