Interesting discussion. I'll just say that it's helped me enjoy cycling more for some of the reasons highlighted. Mostly on road and smooth trail (man made local trails and BMX) for me rather than big Rocky adventures (getting lost and broken!
) For sprints and blasts I love it, and the confidence of not losing a chain or checking it. I now opt for a slightly too easy gear now rather than too hard to avoid pushing my aches too hard and any impatience/potential road rage. Loved it. Enjoy the ride. on my geared modern I still only have 9 gears, almost enough... SS stops me fiddling with gears and selecting a too high torquey gear. less is more I find with SS, de clutter the mind a bit more.
My main commuter for the past few years on and off has been SS, though I'm going to build a mudguarded several geared commuter as the long loads get boring and the 2 hills can be tiring.
