NIB/NOS Crud Claw Cassette Cleaner Gizmo Gadget: Retro 1990's Weirdness - Black Anodized
This little trinket from the wild and weird early 1990's attached to your dropout under your quick release, and weaved through your cassette cogs to clean the mud and gunk as you pedal. Did they work? I don't know. Never used one myself. But if you're doing a very 1990's build, it would add one more point of interest from the culture of the era.
