$1270 to save 1/2 lb at the rim?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

No, if FTP < 2.8 watts/kg, the money could be better spent improving oneself.

If you don't have a power meter to measure FTP yet, the money should definitely be spent to procure a power meter first.
This is pretty much why I don't worry too much about how light my bikes are. I have no idea what my FTP is, but I'm fairly certain I'd fall into the "No" category.

That said, there's nothing wrong with someone spending money on light bike parts because they like having a light bike. Everyone doesn't have the same priorities. I see plenty of beer bellies on expensive race bikes.

Are you having them take apart and rebuild around the new rim? You would probably be better off having a new wheelset built and selling the old set assuming they are in good shape still

Nope won't make a difference...emotionally and psychologically it might and to some people that's worth $1270.

The same question still exists after that change. NOW would you spend $1200'ish to save a half'ish pound? I assume the answer is 'no', but the quoted response does not really address the question (even if the pound of water was rotating weight, somehow).

The answer would still be no. The question is at what monetary price is it worth it? That answer is different for every person. The OP has to answer that question on his own. If it is worth it to him, then he should get them. My opinion, or yours should not matter at all.

I can get Light clinchers, Sapim spokes and Mack hubs built locally for $870.

Claimed weight is 1357 grams.

This would save 253 grams or just under 9 oz rotational weight, most of that at the rim.

Tubulars have been ruled out for a variety of reasons including the fact that they don't make the tires I like, Vittoria Rubino G+ Speed, in tubular flavor. The next best tubular tire is the Corsa G+ Speed but the tubular flavor is 50 grams heavier than the Rubino + tubes. The Corsa tubs are 23 mm only and I run 25's. The Corsa tubs are insanely expensive.

Anyway, $1270 to save 7.9 oz is a different equation than $870 to save 9 oz.

The discussion here has been great and I really appreciate it. It still isn't compelling enough for me to start clicking a bunch of "Submit order" buttons but the input has been great nonetheless.

Light clinchers, or Light Bicycle clinchers?

Sorry, Light Bicycle, the wheel company.

Sounds like a better deal to me.

I love the completely random and arbitrary numbers you selected.

It's diabolical to think that you can train, lose weight, AND have better technical performance all at the same time, right?

Don't worry. People advocating for a specific FTP for a particular aspect of technical performance probably don't know what FTP is, period.

Depends on what else you want. In my grand scheme of things a power meter of some sort is my next "luxury" purchase. Garmin Vector 3's or whatever is out when I decide to open my wallet.

If saving weight is the only goal, you can do it much cheaper. I have a couple of pairs of wheels I build using components from bikehubstore.com that weigh 1285 grams. I used their lightest hubs with Kinlin XR-200 rims, 20 Sapim Laser spokes in the front and 24 spokes in the rear with Lasers on the left and Sapim Race spokes on the right. The fronts are laced radial and the rears are 8x16 laced radial left, 3x right. I'm 170# and they've held up fine on crappy New England roads. Oh, yeah, they cost under $250/pair to build! Even if you add $100/pair to have them built, they're still a bargain.
