Haven't done whole lot to my mountain bike to winterize it yet. We had bit of snow couple weeks ago and went out for a spin in it. Traction wasn't too bad, had to adjust to being more easy on the acceleration. Only problem was after I left the LBS (ordered some Nokian studded tires front/rear). The hill is quite steep in this area, 2-3 steeper than boat ramps easily. Well it was evening and the slush had started to freeze and had heck of a time climbing the hill. I had skirted to a side road for less traffic and hoping the old cobble would help let my tires grab. Wasn't helping much. Slip-grabbed whole way up. about 3 blocks till hill flattened out some.
