I want to get a bigger rear sprocket for hills blasting. I have the axle all the way back on the dropouts, so there is room to go up. By adding 4 teeth, how far up on the dropouts do you think that will go? Is there a quickie math calc I can use to figure this out? I could measure diameter of my existing 48 and find out what a 52 is... but that sounds like hard math work for me to figure out right now.
every tooth is one half inch of extra chain. You are most likely going to have to add links to go up 4 teeth
In case somebody searches this and lands on this thread in the future... I figured out what I need to do, which is nothing in my case. My stock Moby chain has 50 links - gearing 11 x 54. This project Moby has 11 x 48 with 49 links in the chain. Since I have lots of room to move the axle forward in the dropouts, I can easily do a 52 rear sprocket.
I think I have my PBGH rally gearing figured out now.
