Around here....things in winter are either:

A) Frigid, but roads/paths clear from being bladed or just plain no precipitation

B) Winter wonderland or left-over winter wonderland.....and things haven't been bladed.

I have two wheelsets...in summer one has higher-volume slicks or semi-slicks (40mm), and the other knobbies of some sort. In winter, the one keeps slicks while the other switches to studs.

Riding studs on bare pavement sucks only a bit less than not riding at all or riding indoors; but on snow/ice is pretty fun so long as it is there to ride on. Otherwise slicks roll faster. Where things get very sketchy--is when it is icy, and the DOR dumps tons of traction sand everywhere; ironically named as it fouls the studs and makes them grab less....and recklessly driving cars still wreck from being recklessly driven.
