A mate of mine rides a Surly Disc Trucker on local RSF rides. I was half tempted; but ( and I'm no weight weenie ) they are so ridiculously heavy. It's as if they are determined to use a sledge hammer to crack a nut. Admittedly their frames are cheap enough but I'd happily pay 40 - 50 % extra for a bit of sophistication if they were to use heat treated Cro-Mo and shed a bit of weight.
