Never competitive on bicycles, but just daily-driving motorcycle I've seen what wind does to a motorcycle with solid rims. "Disc" wheeled Harleys were a popular aesthetic choice for a while, but when slammed into by Santa Ana Winds it would force them across the road tires screaming as they tried to fight the wind with out suddenly falling over when the gust ended. Even with "normal" rims the wind would shove me across the lane when the gusts hit. Quite the pucker moment. I think the cross-sectional area on those bicycles is much more - I don't imagine anyone riding a dual disc bicycle would stay upright in Santa Ana winds even in neighborhoods.

This is pretty awesome to see y'all experimenting with disk! We/...some of us.... run carbon fiber rims on our bikes and recently have been experimenting with carbon disc mounted on our rear wheels for aerodynamics to get top speed. It really works at higher speeds roll racing between 160-215mph the gains have been backed with Dragy data! My bike would top out in 9/10ths mile at 209mph and with rear disc I'm hitting 212-213 mph back to back. I had to remove the carbon wings off my bike because they caused over 45lbs of down force at 195mph which scrubbed off mph. I really enjoyed the video and learning just how much stuff transfers over between our bikes, its insane how far technology has pushed us in the past 15+ years.

I had a disc on my front wheel on my BMX bike. I did a wheelie right as I was hit by a strong side-wind and my front wheel got blown side-ways and I flew off the road. I would race with the disc but soon realized it was dangerous. If I were to be hit sideways by a strong gust while in mid-air off a jump, I could get very injured or killed. It did look cool and my bike had a cool drum humming sound but that also meant my competitors could hear me coming as I tried to swoop them.

I think it depends a lot on rim profile and the tire fitted as well ... I run 65mm deep front with no issues (and live near the sea, so lots of crosswinds) it only gets twitchy if the tire gets wider than the rim. It helps to have a deeper rear wheel as a "stabilising" effect. I used to run box section 24mm deep thinner wheels and it was not better (sometimes worse).

Wrapped it in carbon 'fibber' vinyl wrap too. Looks real. I kinda wanna fit the other one to the front just to experience it.

recumbent riders often use disc in frontwheels. They made the discs out of Kite cloth, which is bend over a circled glassfibre rod. I rode frontdiscs on 2 bikes with 20Inch front wheels. 1 bike rode fine no issue, 1 bike was slightly uncomfortable. The geometry of the steering is very important for the handling in crosswinds. But with bigger wheels it also gets worse.

Francis, it might be interesting to test this setup with the new set of headset bearings that don't need lubrication because the balls are encased in some kind of solid silicone. The drawback is that these bearings are actually slow, but in a case like this, it would be perfect to dampen a bit the twitchy nature of the front end. Big advantage, you never need to service them, ever ! And they also have a lifetime warranty. GCN Tech, a while back, showed the article describing these on their "Hot Tech" segment, and I thing the new Colnago C68 has these. Couldn't find them on the net, and can't find the video GCN Tech (Ollie and Alex) talked about those. Keep up the testing, very very interesting and a lot of laughs.

been said already but this is fairly common on recumbents. I've driven two recumbents with disc wheels, but due to the different handling it's not that bad. Also 406/451 wheels low down barely catch any wind. Doesn't really speed you up when you're 300lbs by the way.
