I'm getting really comfotrable on my fixed gear bike now, and I'd like to experiment with fixed/ss winter riding.
Living in Finland I face 20-30cm of snow in the mornings, and slush and water is in rich supply. So I'm thinking of setting up an old hog of an All Terrain Bike(remember those horrible early 90's jobs? this is one of the slightly better ones) with a 17t fixed cog and a same or near same sized freewheel.

Cranks I have no idea about, and I'm not very knowledgeable about BBs either. I have a old set of Shimano 105 double cranks I think should fit it. Maybe I'll have to get new cranks. Thinking about a 34t surly stainless chainring.


I'll leave the front wheel alone except for the tyre-change, and rebuild the old wheel(cheap rim) or build a new one with a Surly fixed/free hub.

I'll probably go with Nokian Extreme 294, 26x2.1 studded tires.

Brakes are cantilever and I'm keeping both on I think.

What difficulties will I face bulding this up, what BB will i need, should I just let the nice man in the bike-shop do it for me ;-)
