Sturmey gearing.

Zene · 08-14-2024, 06:10 AM

Hi ... the Sheldon bike calculator does not address changing a 3 speed hub input gear that I could find. Example: 34t crank - 24t input 3 speed - 22t output 3 speed - 28t cassette.
I'm getting nowhere trying to juggle 4 gears. Can someone help this tired old biker?
Thanks, Zene

Gotta do some math, I'll get back
from what I can read, your gear ratio is 1.42 but what's your goal?
