great, that is what I thought, I had a Brompton dealer tell me you need a 28hole wheelset for a Brompton
the standard brompton front hubs are 28 hole
the SON for Brompton is 28 hole
the new rear hubs (2speed brompton, 3speed SA and SRAM) are 28 hole
also from brompton you can get 36 hole rims for older hubs
(I don't recall at the moment if it was the 5speed Sprinter).
With 32 holes you need other hubs e.g. the pantour
