So, when I was out for a ride, I had my daughter follow behind me in her car - it wound out at about 48 mph. I didn't hold it wide open or anything, but it just sounded like it was revving pretty hard, not having a tach.
So, when the sprockets show up, I'll do a bit of experimenting. I think the 16 will fit with no chain mods, but I think the 17 might require a longer chain. I'm partial to the 17, since I'd like a more relaxed road ride, and it's already geared low enough in first for the casual trail riding I do. We'll see how it performs.
That, and mirrors, and I should be good to go!
