The little knobby on some seat stays you can hang the chain while removing the rear wheel. As the title says, where can i buy these? I'm about to paint strip and modify a frame and would like to add one.

I couldn't find any when I was building my first frames. I guess a chain hanger is not in-style anymore.

On the steel frame I added a brazed-on H-barrel and then put a pan head allen screw (lots of lock-tite) sticking out as a hanger. Not sure the name of the H-barrel - it is for rack mounts on the chainstay. A threaded eyelet would likely work just as well.

On the Ti frame I just added a waterbottle eyelet which is more slick IMHO.

Ceeway in UK has them. Or you could easily just make one. Just need a little nubbin of metal. They're called "chain hanger pips" in case that helps to find them.

I place my chain pegs on the chainstay just foreword of the drop out. This way my hands stay clean as the chain naturally drops onto and lifts off the peg as you "roll" the wheel out or in the frame. Andy

You probably should tell us where you are located.

Far superior to a chain hanger for daily use. If you were making this bike into a rinko bike, it might be a different story, but then the chain hanger would be up by the brake bridge. If you want to do that, framebuilder supply also has those.

My travel bike has both.

As @guy153 mentioned, Ceeway has them, Silva Art. 297:

Otherwise, a simple nail, trimmed to length, often will suffice.

Framebuilder Supply in Portland has them.

I already linked to the frambuilder supply page, but the OP apparently disappeared.

Many bikes have simple chain hangers brazed on. Get them at your local hardware store. Cut to the length you want.

That's interesting, I wonder if that's how they started out before someone got the idea of machining them.

30 years ago I was working in a local ski and bike shop and a Serotta came in for work. Even back then I recognized the builder and took a bit of extra time looking up close to the frame, seeking any insights. What I found was the pump peg was a common nail with a 90* dog leg. If Serotta had filed off the little ribs that are just below the nail's head (now above the peg's base) I might not have ever noticed this. Andy

The ceeway ones are cast I think.

Casting is likely. The place that used to machine them in the U.S. gave up on us framebuilders years ago. They were a bit of a pain to deal with anyway, but as a machine shop that makes sense.
