All of the Stooge bars have a larger sweep angle than pretty much everything on the market, except Jones H bars. OK there’s a couple of others, but.
I find the large sweep aids hand and wrist comfort, especially on a rigid bike like the Stooge where the idea was to get your weight off your wrists allowing you more control. You can move your arms to control direction far easier than when your not leaning on your hands.
As an exaggeration try grabbing a broom handle as if it was a pair of bars at 800mm width, fairly normal Nduro width. Now hold it out in front of you at navel height with your elbows slightly bent. Put the broom down on a kitchen work top height, stand in front and spread your arms to the same width without holding the broom. Relax your wrists and see the wrist shape difference.
It makes sense to me. It’s also far, far comfier.
