What is the point of canted wheels on a wheelchair? I see no obvious mechanical advantage and some serious asymmetric bearing stresses as a downside… is it just arm ergonomics for racing?

If both wheels were straight down and also easy to get a lot of torque down, they'd be so narrow as to be dangerously unstable

Think about how much force you can apply with arm extension You can apply more on a vector pointing out from the origin (shoulder) vs one pointing vertically that does not intersect the origin. Think wide-grip pushups vs regular. Plus, yeah, cornering
