Over my time here on BF I have read a lot of peoples' posts about how they were into fixed gears before the fixie boom. I have also read a few times that it was common for people to keep their gears inches in the high 60's for street riding. So I am curious, how did the mentality that 70-75 GI is best come around? The idea of MASH

Did it start as a way to separate oneself from roadie culture and their SPIN mentality? I love my multi-speed, I love my fixed gear. I started riding fixed with 52:18, I found I hate mashing and moved down to 48:18. Still then I wanted to go lower and I went 48:19. Here I am happy. To hold 20mph I have spin as I would on a road bike and I'm not scared of hills because I have learned to really crank.
