For the last several years we have used Supershifters (each with 2 cims) and are currently looking at options for next year as our season is now over.

Why do you need the second gear ratio? Do you intend to drive in one ratio and use the other for a specific purpose? That is drive in "high" all the time and switch to low when you need more torque?

Alternatively if you just need to slow down your drivebase for specific maneuvering, like last year's bridge you can always implement software to limit speed.

Edit: Next year we are hoping to transition to a sheet metal drivebase and hope to better integrate our transmissions into our frame. We are currently looking at the WCP plates that use AndyMark internals but nothing solid at this point.
