Hey all,I'm trying to swap the sprocket on my Nexus 7 hub,but it's way different than my 8. It's an older model SG-7R40 with roller brake. The 8's and newer 7's just have a nut holding the shifter cable in place,this one has some kind of extra plate with a hex bolt in it. I checked Shimano's tech site and found a bunch of other 7's,but not mine. Anyone have a manual or exploded diagram they can mail me or point me to? Or just some clear directions on how to get down to the sprocket? I'm pretty sure once I get down to it it's just going to be held on with a snap ring like the other models,but I'd really like a diagram to see what I'm getting into so I don't mess something up. Thanks in advance.
