I am new to fix, but this summer I did VA to OR on a geared touring bike. Fix touring is possible. However the simplicity of a FG may complicate things. It is relatively easy to chose the appropriate gear for urban areas or a hilly commute, but what is appropriate for Kansas may not work in Appalachia. I am not familiar with the topography of Canada but would imagine it is similar to the US. I would be afraid of spinning myself to exhaustion or killing my knees. Even geared touring presents potential knee issues. Gordon Taylor is traversing a relatively flat area of the US, I don’t know about the rest of his journey. Personally, I feel that FG touring may actually detract from the cycling experience and isn’t that what FG is all about? Regardless, I am mighty impressed by all who pull it off.
