They're about 4" inboard from the dropout, I've never seen anything like it. What do they do? It's a 1987 Fuji Ecco, if that helps.

It's common for 1 on the seatstay. It's a chain holder for when you remove the wheel. Is there one on the chainstay too ?

Now start a thread about what chain lube to use

Your chain looks somewhat less than perfect. Maybe that's the point.
My 91 Giant mountain bike has one of those on the outside of the non drive side chainstay.

I can't figure out which way is up in that pic, it almost looks like a chainstay in the pic, can't think of what one there would be for.

But yep, chain hangers are great. Just remember to take the chain off of it after replacing wheel.


Ahhh, now I get the pic. Typical chain hanger is silhouetted in the foreground. Chainstay nubbin has me perplexed. maybe factory screw up. chain hanger brazer guy had a chainstay in his stack and just brazed one on there before realizing it was a chainstay???

A few builders put hangers on the chainstay, This position works automatically catching the chain when the wheel is dropped, and quietly out of the way once the wheel is back in place. It's nice because you cannot forget to remove the chain from the hanger (kind of epassive seatbelt, of chain hangers).

BTW- one of the slickerst versions (when it worked) was Campy's right dropout to which accepted a short arc segment. You shifted beyond the high gear sprocket and landed the chain on the segment. Remove and replace the wheel without dealing with the chain, then replace the wheel, shift back to the freewheel and you were good to go. Unfortunately right side space is too valuable these days to spare the 3-4mm this device needed.

Oh, dirty chain. Yeah, I just picked up the bike on craigslist. It's in the process of being torn down and gone completely through, and I think I'll just opt to replace the chain.

Interestingly, the catalog page does list "double chain hooks" as a feature.
