Winter ate my chainring

And now spring is eating my tires. Yesterday I had a flat on the way to work and another on the way home. Rear tire both times. I think it's the combination of debris on the road, exposed by the receding snow, and the worn-down state of my rear tire. I swapped the tire (a 700 x 32 Pasela) for a less-worn one so we'll see if that helps.

With any luck I'll be able to get the new winter bike assembled on the weekend, just in time for spring. I think it will have to be redesignated the new mixed-terrain bike. Time to go tire shopping.
