EDIT Despite my long post, I want to see your snow bikes as well
Not wanting to subject my existing rides to the elements, I hadn't been riding much with all the snow lately. On Friday I finally threw up a craigslist WTB ad for a cheap frame for 27" wheels, as I had a set lying around. Somehow I ended up with this:
25" 1986 Scwhinn Traveler in cadet blue plus it's original crank, after 8 miles of thinly plow packed back roads.
I've had to deal with a couple of quirks; the rear end may have been re-spaced to 120mm, so it takes a levers to get the wheel in, the seat post binder was gone so a nut/bolt/washers fill that role and the rear drop out is half permanently filled.
Luckily the 3rd (of 6) smallest cog, a 17, is about inline and works with the room I have, although 42x17 is a smidge taller than I'd like for slumming around. Half links have made the shopping list.
It also turned out the rear wheel has a flat spot in it (bent inward), but it'll do for now.
The entire frame is coated in boiled linseed oil, inside and out. I used a piece of old brake housing to snake a soaked rag up the down tube and back through the chain stays. I squeezed some into the vent holes. I haven't taken the fork off yet, though
That stuff isn't nearly as bad as I've read it made out to be. It was dry by the next day.
The jury is still out on whether I prefer skinny tires to 2" MTB knobbies. My hands were rather clenched most of the ride, but I didn't take any spills.
