fwiw one of my pals races the Scottish dh series, 6ft4, built like a brick shit house, 120kg - you get the idea, races on DD with inserts.
Seems like assegai dh casing does actually have a folding beed version though.
Is there a release date for the raaw dh frame yet?
That's interesting. I have front and rear DD on the Madonna, both with inserts.
Your point about the rear hub scuppers re-use of that rear wheel though, which is a bugger.
