I was super excited to take the first ride on my freshly 650b'd track bike last night.
I got a mile and a half from home when the rear flatted. Since I was so close to home and didn't have much light left anyways asked my wife to come pick me up. Thankfully she took pity on me
I've got no idea what caused it, I pulled the tube and a quick inspection didn't find anything obvious
Bummer.
