I've ridden well over 75,000 miles on Sturmey 3- and 5-speeds (the 5-speed has two indicator chain/rods) and have never broken one (maybe 'cause I carry a spare in my tool kit?). I also ride a Shimano 3-speed that is an early version ("Type F") that I have rebuilt several times, and in my opinion is not nearly as bombproof as a Sturmey. Plus, it takes a unique tool (found one one ebay cheap, fortunately) to remove the "ball cup".S&A 3 speeds (no failure prone little chain coming out of it, but a sturdy bellcrank actuator
