+1 My next bike will have a Rohloff at any cost.
+1 The 11T cog is a boat anchor.
+1 The chainline for going 16 to 22 MPH is always crosseyed. In/out or out/in combos, take your poor pick.
+1 Single steel cogs and chains last forever. See pic of mine and dads 1938? Rudge. Used every summer since 1968. Chain not even clean, lubed with plain oil. Before that it commuted to work for 10+ years.
At least 28,000 miles I figure.
