So on my seemingly never-ending quest for a new street bike setup, I've come across internal gearing hubs, notably, Sturmey-Archer (of course).
I would like to know on the operating "restrictions... meaning can I use it with pretty much any sort of bike frame (not for off-road riding, of course)? What are the disadvantages?
Also, what are the differences between the Sturmey Archer S30 and the new Sturmey-Archer S3X (which I'm not sure if it's out in the market yet)? Is it that the S30 is not fixed gear, whereas the S3X is? The Shimano Nexus is also attractive with its 8-speed.
I'm thinking of possibly getting a steel road/track frame and putting one of these on - I like the simplicity of SS, but I live in a hilly area so having a couple of extra gears really wouldn't hurt at all.
Is this a viable plan? Any advice?
