Looking at the US digital picture of the mention encoder, there is no bearing for the code wheel. This means that the user must provide the shaft and there are limits on shaft wobble and alignment. The Grayhills I believe include a high quality bearing and with the proper coupling can be more tolerant of misalignment and slop. I believe this means that to use these encoders a team would have to add a shaft, take off gear and bearings to the KOP trans. A bearing and shaft type encoder could be add to the KOP trans at the output shaft with a mounting bracket attached to the frame with a flexible coupling. While the Grayhills are more expensive, the time and effort maybe less for the mounting.
