I'm 54 and after getting into single speeds 4-5 years ago it's all I ride now. I have a room full of geared road bikes collecting dust. I ride 5-7 days a week for 25 miles minimum and in 2022 I have ridden nothing but my Wabi and my Swobo rain bike. I'll put my other bikes up for sale one of these days, but I just dread dealing with people on craigslist.
