S S Machine Bicycle Torque Couplings 28 6mm 31 7mm Stainless Steel | eBay
i don’t know where one buys these otherwise, but seem reasonably cheap if you are of the weldy your own frame persuasion.
i am pretty fucking tempted to stick them in my soma, but seems a bit silly.
Leave it to a framebuilder, this is an area where the money is better spent getting it done right.
good, but not great, price.
I predict a US small volume effbuilder / hobby builder will snap these up. S&S won’t sell to you unless you’re insured etc, so they have to resort to buying wrecked S&S frames to get them.
Greenspeed however, will sell to anyone!
when i said ‘sticking them in my soma’ i meant getting someone else to stick them in my soma.
