They sound like a dumb way to add weight to your bike. If you want an aero REAR fender, maybe useful as a fender. Stay away otherwise.

Maybe they should market them as Uber AV detection enhancements.

I can't figure out what they are supposed to do from the website.

The home page of any product website should always answer the question "Why?"

Not going to watch a video to get that info.

I wonder if they make noise, and if so, how much.

I'd wager yes.

Let's add weight and wind resistance to the worst possible location on the bike.

The extra weight on the wheels helps with momentum and traction.

OMG! AERO HAX!!!

Serously, though, it's probably of minimum benefit for most of the conditions most of us ride under. Probably shows some improvement on the Velodrome, or sustained high speeds coming down a CA mountain pass.

More noticeable benefit to be gained under '99%' conditions by a low-spoke-count 'semi-aero' wheel with bladed spokes and good hubs. Heck, probably more benefit in fitting quality high-end tires.

I was just going to say they are junk without actually looking at them but I decided I am going to be a fair person and look at the website first...Verdict: JUNK JUNKITY JUNK JUNK JUNK! If you want to waste your money and install them yourself and never let your wheels be seen not moving go for it but I wouldn't want to be so embarrassed. At least if you crap your pants it could be for involuntary medical reasons or there wasn't a bathroom nearby and you didn't have a good option!

Just in case you thought about those goofy "aero" fenders, don't do it, please for the love of all that is good, don't even think about it. Getting patents is not a sign you are doing something good it just means you have filed for patents and they got issued because nobody else has done what you did! In their case nobody was dumb enough to build hideous aero garbage to add weight to your bike so you can go fast down a hill and pretend you are super aero.

At least those ZIPP sawtooth wheels look kind of cool.

If they're serious, they should pony up for wind-tunnel testing and publish the results, but as tiny as those little vanes are, I doubt they do more than add weight and probably make noise. Ditto for the fenders.

They tout the as adding visibility for safety. There are likely better ways to add visibiility than by adding an ounce or two of rotating mass, near the rim, to both wheels.

I'd like to see what some of the engineers like wphamilton have to say about these products. Above my brain grade.

Well, you posted in here, too...

It actually looks like a legit product, but it seems like they went from theory to production without doing any analysis or testing in between, other than SOTP.

My 6-y/o wants to know if they come in pink, she wants them on her beach cruiser.

Quite the opposite. Even aero rims can make a bike almost impossible to control in strong cross winds.
