Don't know how to name a topic. I want to ask if i right or not in comparison, because gear ratio isn't so accurate I've tried to calculate difference between 26 stock transmission and my bike transmission.
Trial stock:
26"
175mm cranks
18-15 gear ratio
My bike:
24"
170mm cranks
18-12 gear ratio
18 / 15 = 1.2
18 / 12 = 1.5
175 / 170 = 1.02941176
26 / 24 = 1.08333333
1.5/1.2*1,029412/1,083333= 1,18778344
(1,18778344-1)*100=18,778344
So, it seems that transmisson of my bike is 18,78% tighter than 26 stock. Am I right?
