So, it was cold out today, but the sun was out, so I took off for a ride on the trails. Yah!
I rode a trail that has a bunch of short but steep hills. After about 15 miles, I'd been riding on a flat portion for a while and had turned around to go back over the hilly area. I was just starting to truck up a steep one when I tried to shift my front gear down. But nothing happened! I thought, "Oh no! What broke?!"
I got off the bike and took a look. It turns out that the whole front derailleur was caked in ice and wouldn't move. How funny is that?!
So I rode the rest of the hills with the ability to change only the rear gears (the front was on the largest, of course). I did finish 21.5 miles before it started getting dark (I had wanted to do 29 today, but oh well.)
Frozen bike parts is a peril of winter riding that I have never encountered before. Note to self: When it's cold and you go through puddles, shift often - even if you don't need to - just to keep the moving parts from freezing solid!
