Blew the rear tire again this morning half way though my commute.hitched a ride home to retrieve my truck and pick up the bike. Got to work and found a large screw through my bran-new tire and tube. After removing the tire and tube I also found four broken spokes. I have yet to inspect the remaining spokes as I have not removed the sprocket but figured I might as well call it a season. I'll accumulate upgrade parts over the winter and regroupe in the spring.
