Additional Wheel/Gear options on R2 Remote

Has anybody found a way to add additional wheel size / gear tooth combinations the R2 remote.

I swapped out the stock gear with a 58 tooth version from BoardBumpers. I was happy to exchange a little torque for top-speed, but now to get an accurate speed readout on the remote, I need a new wheel/gear combination which would be 200mm/58T.

Is there a way to add custom ratios?

 

175/66 should be pretty close to give you the right speed
