I've seen a lot of posts making a fetish of internal gearing. Why? Maybe I'm missing something.
As a kid I had a 3-speed that gave me no end of pain. I had to coast to shift, and if anything went wrong it was hidden inside the hub, out of my reach.
When I got a 10-speed I loved it because all the gearing was visible. Problem? I could see it and fix it myself.
Are internals lighter, or more durable, or what? What's with 'em?
