I have been a big fan of internal gears for the past 6 years ever since I purchase a old British AW 3 speed as a back up for my road bike. I gave away the road bike when I start doing serious riding on the 3 speed and never looked back since. Since then, my new bike was modified with a three speed hub and another new bike coming soon will also have an internal gear drivetrain installed. And I live in an area surrounded by sharp steep hills!
