OMG you aren't going to believe this
Riding thru the neighborhood I spied a Hardrock Specialized in the TRASH. Both tires flat, back wheel removed, and the chain is looped just like this one!
I asked the people living there, they said it was being tossed out. On closer inspection it looks almost new. No rust, dust or wear. The brakes look new, the rims look good. WTF??? I can only guess they took the tire off to fix the flat, somehow got the chain tangled and just decided to chuck it.
I loaded the frame on my shoulders and carried the loose wheel on the handlebars home. This afternoon I futzed with the chain for a half hour with no luck.
I see a chain tool in my future.
