If someone helps me with the 8th cog delema,
What is max speed possible 10\38. Say 75 and 100 rpm? Please.
38/10 = 97 gear inches. With a 26x2.1 tire, 75rpm = about 22mph and 100rpm = about 29mph. If I were you, rather than trying to get a 10-tooth cog on there, I'd look at getting a 42 or 44 tooth large chainring.
