My Steamroller is a bit twitchy in the snow even with 40mm Nokian Hakkapeliitta 240's. My cyclo cross bike handles better, even with 32mm knobbies, and I think this may be because the cross bike has a much longer wheelbase (partly because it's a bigger frame). So I'm considering using Surly Monkey Nuts to extend the drop outs to get the rear wheel further back.

Anyone tried something like this?
