According to your link, the rims are 390g, the spokes are 4.8g, and the front hub is 65g. That makes the front wheel 550g.
The rear calculates out to 697, total for the set 1247...
If you actually weighed the from wheel at 468, i'd be pretty concerned, because a 307g rim that is designed to weigh 390g must have an awful lot of those "thin spots" that show up in the second link you provided...
I'm not trying to give you a hard time, I just happen to be looking for a lightweight set of carbon clinchers myself, thinking about the new Schmolke 45 clinchers, which come in right around 400g, which is about the lowest weight i've seen for a wide aero 45....
Ok so the rear is 727g? The Ed rear hub is listed as 200g, and say 120g for spokes/nipples; that would make the rim 407g. That's pretty damn light for a 38mm clincher, but let's say that's correct. So the front rim is the same, so 407g plus 100g spokes and 60g Ed front hub = 567.
Farsports 38mm x 20.5mm carbon front wheel 468g
Is this correct? Seems too light for a clincher..what hubs are you running?
Yes, it is surprisingly correct. They are unusually light with the wheelset coming in at 1200g. The hubs are EDHub. I'm guessing that they are able to get to that weight though a combination of the narrow profile, the lighter hubs, and a minimal layup, which requires a 90kg weight limit on the bike. They also make a UCI certified version, which is 23mm wide with DT Swiss hubs. I was nervous about structural integrity and braking temperatures, but there is a pretty sizable thread on this site with good reports on the wheels. I've also found the braking surface to be barely luke-warm after several minutes of heavy downhill braking.
