I'm a Bike Friday nut (now have 4) and once bought a set of slightly used Rolf Prima Accels in 406, thinking I'd use them for a BF build.
But no. The Rolf front was designed for Dahon (jetstream, helios etc.) and the front hub is much too narrow for a BF fork without resorting to some kind of hollow spacer, and I didn't want to go there.
One caveat: IIRC, you can't true these wheels without removing tube/tire first.
I remember reading in A to B magazine that readers had experienced QC issues with these wheels. They never specified what issues, early production run later fixed, etc.
