ok so it seems that 46/16 was a tad ambitious. Especially with the heavy-rolling studded ‘cross tyres. Gives me almost 79 gear inches and a pile of resistance. So I ordered up an 18 tooth cog from Ben’s Cycles.
Also, got the bottom bracket rebuilt on Project Curbside. Went real smooth. Headset tomorrow and then I have to order parts (my wallet is quaking as we speak).
