Ok guys. Finally got my bike back from the shop. The SRAM 2spd fit is fantastic. Was able to keep the 12ga spokes also. Looks great on the bike. Only had time to take a quick spin around the shop but I'm very impressed so far. The rear sprocket is smaller that the original one so pedaling take just a little more effort but also takes considerable less pedaling. I believe I may try a couple different sprocket sizes just to make sure which one I like more. Got it to kick in to 2nd gear a couple times and it seems to kick in just when you want it. Right about the time you decide you're pedaling fast enough, she shifts effortlessly into 2nd. Super smooth and quiet ride also. Pretty sure I'm going to enjoy this hub. I will post an update when I get a chance to put a few miles on it.
