Just got back from a 'personal best' ride. Until today the coldest I'd ever biked in was -25C. For those who still think water boils as 212 and freezes at 32 here is a conversion chart:
I discovered a few things to watch for. My gear shifter was frozen and so were one of my hand brakes. Even after I loosened up the shifter, gearing up was slow and there was a 2-3 second pause before I finally got the gear. Does anybody know how to fix that? I've already got everything lubed up.
I ride a Bianchi mountain bike in the winter. The only reason I chose it was because someone sold it to me at a very low price. It does have knobby tires and someone added fenders which helps me on those other days when there is lots of slush.
I did 2 20 minute sprints but they weren't that sprintish because it was so hard to get the bike moving.
On one very long hill I was in low gear (well 6th) almost immediately. I found the only pain was from my glassses. The frames got so cold, they were making my face ache.
Towards the end, I had to open my pit zips a bit because I was starting to sweat. I'm always amazed that people think I must be freezing when I bike in the winter. They stop when I'm locking my bike and ask: "Aren't you freezing". Today it was quite amusing, because I stopped outside a shop after my first sprint and a homeless man was begging out front.
He said to me "You must be freezing!" and I answered, "I'm exercising so I'm probably not as cold as you."
So everyone, got some ideas on what I can do to improve my cold weather rides?
