I seem to remember Merlin Cycles punting out a Rock Lobster XC racer a few years back that was so light it was deemed a 1-2 season racer. If you could get one of those that wisnae bust you could get pretty light I'd reckon. Also some of Dave hindes on brand XC frames could be built up scary light I recall. Probably talking rubbish, the past is a different country and I dont speak the lingo :roll:
