After learning of Larry’s Full Fat dilemma with the chain being so filled with mud that the chain tubes became totally clogged, I initiated a conversation with Patrick Selwood of ICE. He is an exceptionally conscientious fellow who aims to please. I asked him if a chain guard of some type might be fashioned for my ICE Full Fat trike. Well, Patrick set to work and put together a nifty little unit that now resides on Bigfoot, which will keep all that nasty dirt, grime, mud, and snow that the rear tire flings around off the chain.
This solution, which he says is a prototype for Rohloff equipped Full Fats, will not work for riders with standard rear derailleurs on their Full Fats because with a derailleur system, the chain must move laterally in a significant manner, which this solution does not allow. But on a Rohloff rear end, the chain never moves laterally, thus this will work. Patrick indicates that depending on customer demand response, such a prototype has the potential for becoming available to other riders (the number of trikers worldwide with Rohloff equipped Full Fats however is relatively low).
Also notice in the photos that I have upgraded my rear elastomer system to green/red rather than red/yellow. This will allow me to carry loaded panniers on backcountry trips without the rear of the trike sagging from the additional load, as it did with my load on the Mojave Traverse expedition. Elastomer strengths are as follows: yellow = soft / red = medium / green = hard. The combination of red/yellow came stock on the trike, which provides a softer ride unloaded, but is too soft with full panniers.
Here are some photos showing the customized chain guard and the elastomers:

The ICE fender moves up and down with the tire and swing arm, independent of rack.
