GEARING HELP

(1/1)

Tbone:
Hey, so i have a 24" cruiser and a 36T front sprocket, i'm used to a 20" BMX, so would have automatically thought a 13T freewheel would be correct to maintain correct gearing. Apparently, this is'nt so, as everything changes with different wheel sizes!.  Any help would be great!!!!

I used to run 44/45- 16 on my 20 inch but now run 38- 16 on my cruiser which feels about right. id stick a 15 or 16 up back with your 36 and see how you go.

44-16  41-15   39-14   36-13   33-12    30-11    28-10    25-9

Because the Wheels aren't 20".  They are 24"

Different Sized Wheels = different ratio if same sized Sprocket and Freewheel is used!!

Wheel size (including tire), Sprocket and Freewheel are all part of the equation!!

New School Racing Section has 2 (or more) Gear Ratio Calculators.    :daumenhoch:
