First time I bought a track frame from a person, than a store.

Came with frame, fork, headset, bottom bracket, and cranks.
Took it out and thought nothing of it.
Was jamming pretty fast, then the drive side crank arm popped right out. Had to Ted Shred into a parking lot.
Didnt check if there were any crank bolts, when I got the frame.

Ruined a new Izumi chain.
