How so?
Sixteen spokes doesn't look like much, but they look like stout spokes, and they come out of the hub on a tangent rather than radially.
Also, they seem to insert on the edge of the rims, rather than in the centers.
I'd like to see a closeup of these wheels.
I think I'll do a search.

Found them:

http://www.roadbikereview.com/cat/wh...9_2490crx.aspx

They weigh 1723g and cost $750.
Another version weighs 1520g and costs I don't know what.
The carbon version weighs 1310g (without quick release) and costs $1300.

They get mixed to good reviews.

That makes me feel good.
My new Canecreek Volos Track wheelset weighs 1766g and costs $450, and gets glowing reviews.

They look like they have similar hubs, with the nipples at the hubs, but the Dura-Aces have "16 standard J-bend bladed spokes...mounted inverted on the rim sidewall with the nipples at the hub for reduced rotational weight."

You guys with the sloping top tube frames and the different size wheels. These bikes rock! But, do you carry two different size tubes when you go riding in case of a flat on either wheel?

You'd have to. Stretching a 700c tube onto a 27" rim is easy (and standard practice), but you're asking for trouble if you try to stretch your 650 or smaller tube around a 700 wheel.

However, in the mountain biking realm, where fatter tires are the norm, there is a new breed of bikes that have a 29'er front wheel (700c diameter) and a 26" rear wheel. Some people will just use 26" tubes for those, and because they are wider and have more material, will be able to stretch them in case they flat the big front wheel too.

Or, you could just go tubeless or tubular.

I've got a 650x23 tube in a 700x25 tire right now. (I grabbed the wrong spare tube on my way out the door.) It's been fine for over a month now.

I like the mild slope on the San Jose too. God that bashguard is fugly though. The On-One Il Pompino is another gently sloping frame I dig.

so lookin' at all these pics and thinkin' 'bout it a lot, i'm goin' to look at the design diagrams tonight for the independent fab "i'm gonna be eatin' ramen for years to afford" steel frame i ordered. i think the slope turns out at 4.5 degrees. i think it'll look good and all. and ride well to boot. :)

thanks for all the pics an' ****!! :)
