It looks to me like the speed on the traction wheels would be something like 3.5 times slower than the mecanums, based on wheel size difference and a guess that the traction wheel's gearing is about 2:1.

The speed difference is mostly due to the size difference of the wheels. The CIM drives the center gear. The Mecanum wheel is driven off a second reduction going one way and the traction wheel is driven off the #25 chain and a second reduction going the other way. (I don't have the exact gear ratios handy - must have overwritten the spreadsheet.)

Ah, yes. I missed the fact that the traction wheel doesn't get the second stage reduction that the mecanum wheel gets.
