He's a newb, he doesn't know what he's saying.
Jim, you know those are $850 wheels don't you? Plus spytech chose those wheels, he built up his bike from scratch. Besides, not every part is chosen just for weight, performance and handeling characteristics are other things to look at. Obviously spytech wanted a super stiff set of wheels. If performance and part characteristics wasn't important everyone here would have at least one part to replace, but trust us, we know what the lightest parts are.
My bike is 15.5lbs, and I could have saved weight all over the place. My seat weights 250g, wheels 1485g, brakes 310g, none of these super lite parts, so another 1.5 - 2lbs, but comfort and handeling and stiffness were paramount on my bike. One thing you have to learn is light weight is good, but it's not always the best for the application.
You shouldn't just tell people to get a lighter part, thats easy, but getting a lighter part that fits the need of that person and does it as good or better then the original is what its about.
Not trying to hassel you, your new here, so welcome. Just keep some of these things in mind in the future.
