Maybe some of you smart fellars out there can help me. I want to be able to calculate changes in gear ratios and wheel size. Maybe we can start like this (I am open to other suggestions too):
d= forward distance traveled with one revolution of the BB
w= tire size
f= front chainring
r= rear gear
I will be building a SS bike with 24" wheels, but I want to be able to select my rings by comparing them to my mtn bike, and I already know all the above variables for that bike. This way I will know how a certain combo will feel before buying the hardware.
