New Track Bike Design

British Cycling has worked with Lotus and Hope to come up with a new track bike that's worth a look: https://www.cyclingnews.com/news/lotus-and-hope-launch-radical-new-track-bike-for-2020-olympics/

Its all about preserving the boundary layer, eh?

Sweet

Personally I'd like the bars a little lower.

And minimizing turbulence

I saw that yesterday and thought it was pretty interesting. I presume that the gist of it is that reduced air resistance between the wheels and frame/fork more than compensates for the increased drag from the higher frontal area. Or maybe it's just a gimmick to psyche out the competition. Who know, the details are pretty sketchy at the moment.

looks fugly, but...

...in a car-wreck-cant-look-away sort of way.

curious to understand the aero theory and benefits of the wide-set fork legs and seat-stays.

"aero theory and benefits of the wide-set fork legs"

Stab in the dark, but flow over legs/stay less disturbed by dirty air off wheels?? In effect allowing for laminar flow [more?] independent of stay/leg turbulence?

Other companies, notably Ridley, have found that they can reduce drag by paying close attention to the airflow between the front wheel and the fork. Their solution is much less radical, but I imagine the principle is the same, at least in part.
