Re: MB Poll #2
I use a Shimano CB-E110 hub on the rear. Coaster brake. Plus a Sturmey-Archer 70 mm drum on the front.
I have a grade on my commute that's steep enough that I won't let my bike 'free fall' when going down. Moderate pressure with hand and foot is enough to keep that bike down to a safe speed.
I also like this setup because your wheels are less complex when you can avoid rim brakes.
