Jugghead (me!) just sheared off my seat binder bolt. At first it was terror when I heard it pop. My first thought was the seat tube had cracked. Then I saw it was a sheared bolt. Then I was just cussing myself. One end of the bolt slid right off. The left hand side is still in there tight. I tried to loosen the left side with an allen but the head is also cracked so it just allows the allen wrench to turn. I didn't want to screw anything else up so I'd thought I'd ask you guys. How do I get the left side of the seat binder bolt out?
