Schwinn Exerciser sprockets

65 teeth.

take offs with little to no wear.

so shiny you can use them as mirrors.

hard to photo well because they are so reflective.

I have 3 in this great condition. Each has a number in the photo. 

When buying, please leave a message for which one you want.

The chrome on the back side of #1 isn't the best.

Can be installed on regular bikes if you use a spacer behind the sprocket on the crank. See the last 2 photos for examples.
