I've cycled to and from work today - there is about 8 inches of snow on the shed roof at home, but out and about there is less and on the roads it's been compacted. It's generally been quite fun, althoguh I need thicker gloves. I've been on 2" knobblies and it's been fine - I've not fallen off or anything, so all's good. However, it feels to me as though although traction is ace going in a straight line - better than walking boots if my 'test' on the steep footpath near home is valid - the steering feels madly skittish, like whenever I steer it's trying to slide away from me, and indeed in the bits of snow on the road where it's starting to break into compacted chunks where some cars have been, the wheel will dig in like on sand and try and pull you one way or the other, all of which combined makes it feel all the time like I have too much weight on the 'bars - which maybe I have: I've not ridden this frame very much; I've only just swapped the running gear off my other bike on to it, and it's a little shorter in the top tube and head tube than the old one, so I lean foward a touch more. Is my experience of riding on snow using knobblies designed for mud typical, and if so, do proper ice / snow tyres make much difference? As I say, straight line grip is fine, it's just when the tyre digs in to the compacted stuff that's breaking up, and when going around corners.
