Rat Bikes! Pub Bikes Beaters! Frankenbikes!

Good spot ed. The downtube shows a frontal impact just below the headtube lug. ooof.

Now that you mention it, I only checked the top tube and headtube for damage. There's a partially transparent sticker on the DT which might mess up the perspective, but I'll definitely check the DT when I get the chance and report back.

Frameset was about £80 posted so not a big loss financially, but it would be a bummer if it turns out to be unsafe to ride.

Checked the frame and the down tube is clearly bent. I guess I'll ride it 'til it dies. A sad day.
