I found that last winter.
It doesn't snow much in Vancouver, but when it does, it's a nightmare for traffic. Luckily for me, I live right next to a MUP trail that leads almost directly to my work so when it snowed last year, I rode the bike into work on this trail but found the longer I was riding in the snow, the more problems I was having with the drive train. The snow built up in between the cogs, compacting into ice, and eventually the chain was slipping because the ice was built up so high, the the chain couldn't grip the cogs anymore.
