Hah! I call that the "Cheeseburger Rule". Sure, I could spend $300 to get rid of 200g from the bike, or I could just stop eating so many cheeseburgers.

It costs a decent amount of money to get the bike to a decent weight. After that, my rule of thumb is that once you get to about 20lbs on a road bike or 30lbs on a cross-country suspension mountain bike, figure $1000 per every pound removed after. (Maybe it's an exponential curve, too, given what the new McLaren Venge is going to cost...)

That being said, I have several ridiculously light bikes, and I *can* feel the difference. Not just in effort to climb, but in rotational momentum when you remove the weight from wheels and pedaling motions. Losing two pounds off the wheels feels much MUCH different than losing two pounds off your self.

-- gnat! (That, and it's kinda fun to watch people nearly launch your bike into space when they pick it up to put on a roof rack.)
