Recently picked up a Dean Titanium frame and with this mounted to it. My first though was something to do with a kickstand, but the jagged side and adjustable bolt holes are throwing me through a loop. Any thoughts?
Looks like the remains of a bike stand to me, someone’s hacked at it with a hacksaw me thinks

I need more phots of the frame… for science

It appears to align with what would be a 3-speed crankset and looking at the existing frame damage it’s right next to, I would agree that it’s an anti-chain-suck device. Titanium is strong, but it’s soft, so it would take the chain less time to chew through that wall. It also doesn’t look very used by looking at that second picture.

Also had this on my bike during the nineties.
You align it best you can with the crankset chainrings to only have space smaller than the chain’s width – so the chain cannot reach the frame anymore …

Doesn’t look like it protected much.
