I've never ridden one and they look pretty clean while still offering me a bit of variety with the 3 speeds.

The bike I'm working on is one of these (but this is not my bike):


I haven't measured it yet for compatibility, but if anyone can offer insight on doing something like this, it would be greatly appreciated.

Also, thanks for all the comments. I'm excited about the possibilities and it's great to read all the input from you guys.
