High-low hubs, low-high hubs?

Hi,

So there's a history of hi-lo rear hubs with larger drive side flange that is intended to, supposedly, improve the bracing angle on rear wheels. I guess Jobst Brandt made a strong case that it doesn't really accomplish that. Anyway, I'm looking at this All City hub that has a larger flange on the NON-drive side. I believe this is especially out of the ordinary. What is the reason for this? Picture of the hub in question below.

Thanks

p.s. usually the larger flange is on the drive side, so I'm confused by this All City hub

To better handle the forces from the disc brake on the NDS? 🤷‍♂️

Could be that I guess?

Not a functional concern with that diameter hub core. Unless soda can thin, itíll distribute the forces just fine.

While Jobst Brandt literally wrote the book, he's not the only one who ever engineered a bicycle wheel.

Two possible reasons for All-City to go with a tall NDS flange:
The "practical" would be to get the spoke hole circle clear of the brake rotor mounting ears..

More likely though, is just for style: All-City's signature is steel -framed neo-retro urban FG/SS bikes. They have two different high-flange 'track' hub sets, a 6-slot and a 5-star "Sheriff" hub. I'm pretty sure the high flange on the hub that's got you so confused is the same slotted pattern as the track hubs.

Sometimes, you do something just for the style, Mr Petersen.

for disc; to reduce adding more spokes on the NDS & to achieve a higher tension, the taller NDS flange shortens the spoke & [in theory] reduces fatigue.

I wonder if there was a production disc wheel that had equal spoke count & flange height, but used thicker gaged spokes (to include nipples) on the NDS?


Personally, I would rather have both sides with tall flanges for a 700C disc carbon wheel. I'll have one less donut to offset the weight penalty.
