I love my Madone and it truly fits most of my needs........but while I'm not a weight weenie I know a pound less here and there can make a big difference on some long rides in the mountains. It gets especially noticeable when they throw in these 4 to 6 mile climbs that have grades of 20% +/- along the way. I've already purchased lighter weight wheels and tires and try and keep my weight as low as I can.
I've just been "toying" with different options mind you......and I cannot afford any more bikes. Goodness, I just bought a Cervelo P2k time trial bike a couple months ago and it hasn't even seen the track just yet. With three college tuitions and a shaky job it just doesn't make sense to even pursue spending more on a bike.
Anyway, I enjoy the pursuit and studying and analyzing all the different options. I popped into a bike shop today looking for used bikes and he had some of the new full carbon Operas on display-right as you come in the door. My, my.......what a thing of beauty with the Opus front fork and seat stays (curved instead of straight) . And to just think if I had $5000 to invest in it I could be enjoying the benefits of that 15-16 lbs!! Hummm.....maybe we need to lobby for tax credits for health benefits for equipment like bicycles.
Oh well, I'll have to settle for window shopping for now.........
