I want to see video of that wheel spinning at 30mph and them throwing a crank arm in it to see what happens
if that comes out good
that is totally, totally sweet.

It’s like I asked the Lew rep at Sea Otter a couple of years back as I was handling the Lew wheel, “So…this is a crit wheel, huh?” 
.
“In every aspect of wheel performance: light weight, torque response, durability and aesthetics, RZR has been conceived and constructed to exceed performance requirements of the worlds most demanding cyclists.”
So the fact that I don’t care much about those aspects listed but would really like to know about aerodynamics means I’m not a demanding cyclist? Or am I unreasonably demanding??

No…it means they took their design approach from the Mavic R-Sys playbook…doh!
BTW, since when does the fact that a wing section has an NACA number automatically mean that it’s super low drag?
swirl lip generator? WTH
well hell, my inner aero weenie was pretty impressed when the worlds lightest wheel
- was 46mm deep
- had aero spokes!
being a weight weenie wheel I will forgive them if it doesn’t have an optimal torrodial shape to the rim or whatever.
I just don’t want to eat pavement if a pedal, stick, or squirrel goes into my spokes

I just found and skimmed through - looks interesting but I think it’s been discussed before ??
Companies don’t make their an ultra lightweight, minimize grams at all cost wheel to impress the aero weenies and triathletes, they make them for the pro cyclists that win their races when the course goes above a 10% grade. And compared to those guys, neither you nor I (or really anyone on this forum, since we’re mostly all triathletes and not pure, Pro Tour cyclists) are demanding cyclists
It’s all relative!
Back when Zinn and the Velonews crew tested the Lew wheels, they reportedly (maybe a photo to go with it?) did some trials bunny hopping on the front and rear wheels and were very confident in the strength of the Lew wheels.
So, what’s “swirl lip technology”? A competitor for toroidial rims?
I actually got to ride a prototype set of these, and they were fabulous. Even though they’ll probably put a 185lb weight limit on these, I’m pushing 215 and thought they were very stiff considering. They do incorporate some of the design elements of the LEW racing wheels, but have been drastically improved. The carbon hub shell itself can take nearly as much torque as a Chevy corvette can put out (about 300 ft-lbs.) And I do believe that they will be coming out with a UCI approved model with kevlar reinforced spokes. They’re pretty pimpin’ if you ask me. But pimpin’ comes at a cost… I know I won’t have the dinheiro laying around to pick up a set.

On the contrary - they only make those wheels to impress consumers. Few pro cyclists care or know that much. And Reynolds only sponsor Agritubel who, apart from Feillu in the TdF this year, are not exactly a mountains team.
Further, the number of important races won on >10% gradients is low. The number lost for the sake of 200g on the wheels is so low as to be neglible.
I rather feel you missed the point of what I said - it’s not about me. It’s about creating a list of performance attributes that ignores the most important one and then claiming that you have addressed the needs of the most demanding cyclists.
The most demanding cyclists from the perspective of an equipment are educated consumers - who care about insignificant details. Pro cyclists care that it gets them to the finish. Which counts pretty heavily against this design.
Lew wheels are gone. Kaput.
From what I understand watching child porn is bad for business.
Reynolds bought Lew IIRC.
bunny hopping isn’t the concern.
making carbon fiber strong in the directions that wheels TYPICALLY see massive forces is easy.
its when you smack it from the side that it gets tricky, especially when you have only a thing spoke to deal with

Well I have some very bad news for these guys as they are not even close to the worlds lightest wheels.

I guess maybe they are the lightest production wheels in the world but you could custom build a set of wheel lighter.
swirl lip generator? WTH
Translation: Our sub-optimal rim shape causes airflow separation. Quick get the marketing guy to make this sound like a “feature.”
I knew you would post that link BMAN!
Well there is even lighter than that but I am not sure what Gunter actually modified to get to just a shade over 700g. The whole bike is 7 lbs. however.

Carbon Spokes…RUN AWAY! haha
