It's demons.
Of course, with more information, other possibilities may come to light.

As for the bike, it's an early 90s Basso Ascot with the conventional Italian BB of its time. The spindles are square taper, but the length depends on the cramkset. I have an ancient Campy NR, but 52/46 is not my idea of fun gearing. I haven't checked for a long while, so I really should look into what's available these days. New is hundreds of dollars that I can't justify on my budget.
