44/12 = 3.6
53/10 = 5.3

That's a big difference. Never mind the leg muscle needed to lug that speed. I did not factor revolutions though. Do like how someone explained cadence is important. Understand that group rides will have riders of varying levels of fitness. But if I'm getting this right. 42/44t with a 10-12 will be enough to peddle hard with a group? This is intriguing, although it isn't in the budget I may actually get my hands dirty and mess with the gears. There is a really good steep hill right outside my studio. Maybe I will look like a nut job to my neighbors and hit that thing two dozen times in an hour lol.
