Today it warmed up a bit....to -25C when I left for work. The cold isn't the problem though, it's the ice all over the roads. My Schwalbe snow studs just don't cut it, by a long shot. On Soots, or even any other bike for that matter, those studs are good for the occasional little patch of ice. Right now, on all the road around town, there are ruts that can be 6-10" deep that are solid ice.
It's gotten to the point that I've reverted to re-studded the ice spiker tires I had last year. It's a long and slow process, but I'm over half done. This year though, I've made a few changes. The resistance on the studs last year was so great, that keep any forward momentum require a lot of consistent effort. Not that it's a bad thing, but when you're reward is reaching a top speed of 8-10mph, it's a little disheartening. This year, I'm taking the same approach, running the pan head screws through the square tread block, covering the head with duck tape and then running a second tube as a liner over the tube that will be holding (hopefully) the air. The difference: I'm cutting the screws down with bolt cutters, so the screw will only be about an eighth of an inch proud, rather than a quarter inch. This should make it roll a little faster (still going to be a slow tough slog) and I'll be able to retain the claw like traction that I get when the studs dig deep into the ice.

I'm also building the studs up around a frame that hasn't seen action lately. My trek. The bike that started my serious bicycle commuting. Some mustache bars, maybe a 7speed cog in the back and a shimano bar end shifter from the parts bin. Hopefully in another week I'll have it all together.
