Yes, Greenspeed, recumbent trike manufacturer and distrubuting importer for Brompton, in Australia

has re machined SA drum brakes to fit in the narrow forks, and build wheels around for Bromptons...

they also re machine the frond drum brake hubs to be single end axle supported for their trikes
(Unless they now buy enough to have that work done in the factory.. )

More likely 24 hole rims rather than 28, since the hubs just come in 36 hole...

Or spread the fork out from 74 to 100.. use the hubs as is.

after market electric conversions already required fork spreading.
