I apologize in advance if this is a repost. I am looking for information specifically about wheelsets mentioned above. First, my average wt is about 165 lbs.. I do not race and normally rides on rollinghills, flat and breezy coastal roads, and some long hills (cat 2/3) maybe a cat 1 and HC in the future. I am currently using a 2012 HED Jet 4, tip the scale at 1680 with QR and Rim Tape. So Im looking for a low profile wheelset for my hilly and long climbs rides, and have these two in sight. Does anybody have any weight information of both RIMS. Shimano claims they made the weight saving through lighter rims but no data available about rim weight, nor the Ardennes FR as well. Is my concern about the rim weight unecessary for the quality of both products? Or the difference in rim weight negligible during the ride? Or better yet, will I see a big improvement from JET 4 with either of these wheelset? Thanks for the feedback.

C24 rims are suppose to weight 375-85g. the wheelset is suppose to weigh 1375, though 1399 is the lightest ive seen/heard so far (usually around 1420g). so they have been missing their quoted weight.
how about the Ardennes+ with the wider 25mm rim? wont be shipping for another month though.
btompkins-despite what I have read elsewhere on the web, a Shimano rep told me the 9000 C24CL rim is the exact same rim Shimano has been using for a couple years now. That puts the outer rim width at 20.8 mm, but I can't recall what the inner width is supposed to be.
PS: to Juanacity - I believe the 9000 c24 rim widths comes in as F23mm and R24mm, at least from what i've read.
The 9000s are the same width as the 7900 (21mm), but did get a little deeper. I really like the 7900-24, have ridden the tubeless version for about 18 months.
I read the same things so that is why I actually asked someone directly from Shimano. The tech docs seem to confirm that it is the exact same rim they have used for years; width and depth. Definitely don't order those wheels if you're expecting a wide rim unless you have confirmed it in your own hands.

On a related note-Shimano does an incredibly HORRIBLE job of marketing/communicating specifics of their products to the public. They have some of the best tech blow-up illustrations etc., but they can't release simple, concise information in the form of news releases like ZIPP and others do. The Shimano people I have spoken to say their new wheels with wider profiles etc. outperform everything else according to actual wind tunnel testing. I don't have any idea if this is true, but they certainly haven't done anything to make this info available or even make the claims to the general public.
