I can't make out the fork ends too well, but I can't see how that would work. I'm no aerodynamicist, but I am a (sadly noncurrent) pilot, so I have had an interest in the subject. I've always conceptualized the primary function of winglets as reducing induced drag by smoothing the interaction of the high and low pressure regions at the end of the airfoil, a bit like an aerodynamic fence. Even if you treat the fork blades as airfoils that both have an angle of attack that is producing lift (i.e., differential pressure) they'd need lateral protrusions. That seems like something that would give the UCI fits. They could just be fairings or extensions meant to smooth airflow around the wheelnut / axle area. I guess you can always make an argument for incremental gains....
The bold is correct. The current design of winglets is what works optimally for planes at the speeds they travel. You can achieve a similar (albeit much smaller and not as effective) effect by sweeping the wingtips back, as well as increasing the wetted area of the wingtips. This only works at lower airpeeds, so may have bicycle applications where it works. It essentially tries to disrupt vortex formation, (by allowing the low and high pressure streams to meet along the trailing edge before spilling over the wingtip) instead of channeling and reducing the size of vortices as with the perpendicular design.
My guess is infinitely marginal performance gains, yet measurable marketing gains $$$$$.

Here's an interesting find around the web:
Feb 25-26, there will be a Track World Cup in Los Angeles.
See y'all there!

So I went to Velo sports center today for the first time, because of school meeting
When I visited the velodrome, Australian team was training with their fancy Jayco skinsuits lol
While I was their I heard "Go Anna!!"
Which means Rio Australian sprinter team is training in Velo sports center training.
Apparently Shane Perkins is not on the list for Rio, so I did not had chance to meet him.....
Anyway I was too shy to talk to Australian team and I didn't want to bother them

Tires mounted on directional track wheels should have the label facing on the left side (on the side that you don't ride on). When it's on the right side, riding on the label could cause a slip at slow speeds.

He does. Most of the time. But only sprinters would care about something like this as well. I just used to sand the labels off of my tires if they were on the tread.

I noticed that arrow, too. But, I think the arrow sticker is installed on the wrong side. The blades should "lay down" as they spin.
So, the wheel is mounted correctly:

He missed the kilo WR here:
Notice the wheel is on backwards.
Actually, Hoy and his staff didn't notice. He read about in on Fixed Gear Fever later. He mentions this in the book "Heroes, Villains, and Velodromes".

The August 2016 issue of Money magazine features a seven-page article on Bobby Lea (I checked on line but there is only a brief summary at Olympic Cyclist Not Doing It for the Money). The article discusses Lea's financial situation, the high cost of world level track cycling, and the magazine suggests a post cycling job path for Lea.

Like other Olympic hopefuls, Lea, 32, hasn’t made much money from his sport and most likely never will. His best-paying year as a cyclist came in 2015, when he made approximately $32,000.
The sport is hard enough mentally and physically.
You ever wonder why great track cyclists don't stay around long? This is one huge reason why.
Why bother? Seriously.

Team GB is on some next-level training program for sure.
I guess the major questions are:
- Did Team GB sandbag (hold back) for 4 years?, or
- Did they truly become faster since the last round of World Cups and World Championship?
