Re: Winter riding -20 and up to -50 winterpeg
Never rode in any thing near -40. But they do love the cold. (Nothing on earth loves 40 below, lol) At temps that low I would think you would have trouble with cables and plastic. Not that I really know but think any thing below zero might cause you problems. I am sure some one from up your way will let us both know.
Side note, you can get studded bicycle tires.
