I did the same thing and assumed a 5/8" bore for the sprockets. So we were rather surprised when our ordered sprockets would not fit. Therefore, I second Andy A's suggestion to READ THE MANUAL. It was unexpected, but easily designed around, and if we were delayed in getting our bot mobile, it was no one's fault but our own (mine). We just took the ordered sprockets back and quickly ordered 2 more 21 tooth kit sprockets.
That being said, the new kitbot transmissions are AWESOME!!! They are easy to assemble, can be used for a variety of configuations and purposes, and are quality-made. If you used the transmissions from years past, you know that there really is no comparison. Any team will be hard pressed to come up with a superior single speed transmission.
All I can say is thank you Paul Copioli. I don't know you, but I sure like your work!
