I know that the idea of having crank arms on a Coker that are adjustable
in length isn't anything new. But here is my take on the idea.
I made up a set of cranks that adjust by a quick release lever on each
crank so that an arm at the end of the crank can rotate to different
length settings. Because the main crank arm is concentric, and the
adjuster arm is excenteric (crazy) the 1956 C&W song "Crazy Arms" is
stuck in my head now.

I rode about 25 miles with them on Friday, they realy make hill
climbing a breeze when set at the max length 165mm and then I can realy
cruise along on the flats with them set at around 120mm and on rolling
terrain set at around 145mm.
