All this talk about weight weight! I am 240lbs. I think I will work on me first. Its not about lightening the rider and bike combo, its about lightening the bike so it is more flickable and easier to manhandle when it comes to that. There is a huge difference between a 260 pound bike, a 250 pound bike, a 240 pound bike and a 225 pound bike. And the lighter the rider is the harder he has to work relatively to ride a heavier bike.
