SJS Cycles UK will ship to places without Brompton dealers, in that country,

otherwise the company has dealers in your country that will ship you replacement parts
Brompton website will tell you where they are.

USA has a lot of Brompton dealers, now.. Nyce wheels in NYC

and Clever cycles in PDX foldabikes in Palo Alto retired and Closed,
he was one of the few US dealers for a long time.

Axle is 8mm, so cones have to be that , most are 9mm for regular hubs..



NB: Ask "Can you get them?", if they don't stock them, already,

... just sitting on the shelf in anticipation of your call..
