Thanks Windell. This is the same encoder that the Andymark super-shifters use (ep4 or e4p 250-250).

They work very well, however, you must set them up correctly.

To install a shaft on them, you have to carefully remove the plastic cover. Then, place a piece of paper over top of the two mounting screws. Finally, push the encoder disk down onto the shaft until it's snug against the paper, and remove the paper.

If you do not do it this way, you risk pushing the encoder ring onto the mounting screws and a single turn of the encoder will ruin it. If you put it frrther away from the optical sensor, you will get flaky results, as several other teams have noticed with the AndyMark shifters.
