Any thought to incorporating a polished metal(stainless) for the contact point surfaces to avoid the worn/chipped/peeled paint look once the dropouts get some wear? I believe this is what the Ellis Signature dropouts have and that my 1989 Schwinn Paramount had as well.

Hey,

Assuming that they work as as planned there will be cast versions but that will certainly be awhile any way you slice it. If/when they are cast it will be pretty simple to have gated molds made to allow for versions with rack eyelets cast in.

Thanks for the comments,
Dave

Hey PG,

You nailed the core concept – ball and socket. It allows for most any angle to be made and a large surface area both inside and outside the tube for brazing.

Thanks for reading.

Hey,

1) they will go on most bikes but not all. In some cases other dropouts will be a better choice. For instance I’m in the middle of a fully loaded touring bike right now and it’s best to build thoe with a long horizontal slotted dropout so the bike can be set up as a single speed if the derailleur fails in the middle of nowhere.
2) mounts for racks and fenders can be added.
3) the Triple F’s are pretty darn light but still might be a bit clunky for earrings……….. but who knows. Set some stones in them and see how they sell.

These dropouts look great and I hope they become available in a less expensive cast form.
The shape also looks like a natural for adding integral fender / rack eyelets on a similiar “petal” form.

It would be especially nice if the driveside eye was dished away from the cassette to allow a thin nut to be used and not interfere with the smallest cassette cog / chain.

That can be for “down the road”. For now, these look really nice.

Hey Dave congrats on the design. Looking at the ball end of them they remind me almost of a ball and socket joint. Two things from the way the photos look it appears that there’s more surface area for brass to hold onto making for what’s potentially a stronger joint. And also would these tend to minimize possible stress risers in the chainstay/seatstay joint due to not having to cut into the tubes? I also like the way they look.

Lovely, of course:
1. Will these go on all your bikes now?
2. Can these handle braze-ons for fenders and racks?
3. Idea for the holiday season: the FFF earrings ( . . . I’ve certainly seen worse).

I’m not a builder but those are fantastic dropouts, Dave. Great work! Photo #4 really highlights their simplicity and design.
