Bent Chain Rings and Wacky Weather.

When I last posted I had taken the Pugsley out on a day with some fresh snow. The snow was covering lots and lots of ice left from some thawing and a rain storm. I wrote about taking a couple of falls in the first 3 miles. What I didn’t mention is a third fall later in the ride while walking the bike down a treacherous ice covered descent. My feet slipped out from under me and I fell towards the bike. I ended up falling on the bike with the handlebar  grips smashing into my mouth. At first I thought I might have knocked a couple teeth loose and given myself a fat lip. I was sore, but it wasn’t that bad. No loose teeth. It was at that point I decided I’d had enough and headed home.

On the way home that day I noticed a new noise while pedaling. Sounded like something hitting something else on every revolution of the cranks. At first I was baffled. But then I saw what was causing it. I had bent the bash guard and possibly my outer chain ring. The noise was the chain hitting the adjacent chain ring or bash guard. I’m using a Surly Mr Whirly MWOD crank. It’s set up as a double with a steel inner chain ring and an aluminum outer chain ring and bash guard.

I’m not sure when I bent it. I’m sure it was on one of the falls. I replayed the falls in my head for the next three days. My conclusion was I couldn’t have bent it while falling while riding it. It’s possible my knee made contact with it as I fell on top of the bike when I fell while walking the bike. Although, I keep thinking if I hit it with my knee hard enough to bend it, my knee should be hurting. It’s not, so I’m not 100% sure.?? Before I headed out yesterday I needed to try and bend the rings back. I’ve never had good luck bending aluminum back into shape. But thirty minutes in the basement with the bike in the Park Tool work stand and some bending in the bench vise and I had both the bashguard and the chain ring back close to true. Sometimes my mechanic skills I better then I think they are.

Fast forward to yesterday, which was Saturday. We’d had more warm weather this past week followed by some wet snow, followed by temperatures around 0F degrees Thursday night. After eleven winters of fat tire riding on snow, I’ve become quite good at predicting trail conditions. Well, at least until this winter. The wild swings in temperatures this year have really thrown me for a loop. I’m not used to January and February thaws as big as we’ve had. Thaws that completely change the snow pack. I thought for sure after the wet snow followed by dropping temps, the conditions should be fairly crusty.

I was wrong. The temperature was approaching 30F degrees and the sun had just come out from behind cloud cover when I left my house. The trails were not crusty at all. These were snow mobile trails, not the local singletrack. I found the trails to be very soft. There had been very little, or no snowmobile traffic. The snowmobiles will compact the fresher snow to some extent. This helps it to firm up with the temperature drop. No such luck. The snow was so loose I was sweating heavily and working hard.

I ended up taking it easy and enjoying the sunshine and snow. Another warm-up and lots of melting were in store for today. Another wild swing in temperatures with rain for Monday. This time of year you never know when the last ride on snow will be. I try to get out there as much as I can.

    Congrats on the chainring repair! I pull off things like that so rarely that I feel like celebrating for you…and I’m glad to hear that your injuries were minor.

    Glad it wasn’t your teeth that were broken!
