You are right... it is high. I made this transmission to be used with 4" inch wheels. If you do a reduction of 10:24 (sprocket), with high gear you get the output rpm of 742.5 and with low gear you get the rpm of 185.63 which will make your robot go 13 fps on high gear and 3 fps in low gear with a lot of torque.

Please read posts 6, 7, 8, 9, 10, 12, 14, 15 in this thread to get more specific specs on the transmission.
