Due to cross-chaining issues, I came up w/ a formula for the actual #
of usable gears on a bike, which is less than the stated number by the
manufacturer.
For instance, on my bike, which supposedly has 24 gears (3 in front, 8
in back), I only actually have 16 usable gears, and not 24.
The formula can be expressed in this form:
(# of speeds by manf) - (# of rear sprockets) = actual # of usable
gears
ex. 24 - 8 = 16 usable
Note that this formula only works if you have 3 sprockets in the
front, and any number in the back.
