Winiums look good for a carbon rim. I wonder about an alloy tubular in the Flo shape. Looks like the closest right now is the Hed C2, which is hard to find as a bare rim. Anything else in alloy tubular at the 23 wide range?

Got the profiles for the 23mm wide Yoleo 38mm and 50mm carbon tubulars;[url]the 50 is the exact same graphic as that on the Focus Carbon site http://www.focus-carbon.com/ProductShow.asp?id=559" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;[/url]; it's probably the same as the Farsports as well although they don't have a cross section graphic. I don't see anyone else (yet) with a 23x38 rimm.

Also looks like none of the 23mm wide carbon rims come with basalt brake tracks.

Yep... but I hear rumors of a lighter rim with a similar profile being available soon.

Any chance you could compare the CFD drag data between the new 30 shape and the 60(assuming the parameters allow for such comparison)? I'd be curious to know how they stack up.

Also, Chris, what is the inside to inside width of your rims if I may ask?
