Just out of curiosity I did a bit of a web search myself and a review on bikeradar, which I think is derived from a cycling plus review, gives the weight of the frame as 3.5 lbs, so it probably is accurate. I've got a 2006 frame not the 2007/8 frame which has completely different tubing, but I'd be surprised if it was massively lighter. I do still have the original wheels on it and yeah, they are rubbish, so could be making a hefty contribution to the overall weight.
