Check out this page as it shows the different ratios:

My Crossroad 8 shipped with a C shaft, which I believe was the 2.07 ratio. I replaced that with the Sport shaft stamped with a B, which I believe is a 1.77 ratio. It was a big help climbing my 10% grade hill at the end of my commute home at the end of my day.
My big challenge right now is to convert my bottom bracket from grease to an oil bath and keep the oil from leaking out. Since I switched to oil bath lubrication I have had no problems with lubrication, grinding noises, etcetera. Changing to oil bath has solved what is to me the biggest complaint about this drivetrain. Now I just gotta keep the oil on the inside...
You might try 00 grade grease. This is what Sturmey Archer uses in their greased gear hubs and is, I suspect, similar to the greases Shimano and SRAM use too in that application. This is a semi fluid grease apparently originally developed for truck transmissions. Supposed to be just fluid enough so it flows back into geartrains if squeezed or thrown out.
