2.6kg is a big chunk of weight to save, though, especially when you weight 65kg, the impact is going to be a bit bigger, then on a 70kg rider. Still, even if I bought a 5.8kg superlight climbing bike instead of my current bike (which is also 8.4kg, funny, that), I'd be looking at a saving of maybe 3% up the steeper local climbs, which would move me from somewhere in the middle of the list in local races to somewhere also in the middle of the list.... it's a really big chunk of cash for not a big difference in placement
