Phil Wood Crank Arm Shorteners: RARE (EXC)
These obscure pieces of bicycle history are designed to shorten your crank arms to whatever length you want. The primary use seems to have been to shorten the arms on a tandem bike, allowing your child to pedal in the stoker position as well as juniors racing. They were designed to fit the profile of the TA Cyclotourist Pro 5 Vis arms, but they may fit other cranks with a similar profile. From the 1970's or early 80's.
Excellent used condition. Some surface marks.
