#!markdown It's a pretty huge variance when you don't have a derailleur to keep tension on the chain -- you have to run the chain slack enough in the right spot to account for frame flex (side to side) but tight enough it doesn't rattle around (falling off isn't an issue thanks to N/W). When the ring is vertically it's most oblong vs. horizontally it's most oblong it's relatively a big difference in the amount of chain it takes up
