Edited Date/Time:
so with me riding 25/9, and looking at this: http://eehouse.org/fixin/formfmu.php i can either run:
13.70 (full link chain)
13.45 (halflink chain)
13.20 (full link chain)
12.95 (halflink chain)
which is pretty limited if i want to run fulllink.
whats your gear ratio? which one is the most common for street, which one for park? did you even consider this when buying your frame?
