The fact that a tubular tire will stay attached to the rim doesn't mean a wheel won't slide out on a sharp corner if the tire deflates or if the rider hits a bump at a bad angle during the turn.
A shallow box rim won't keep a rider from sliding out on a sharp corner if the rider hits a bump, the wheel loses contact with the ground, and the rider is at a bad angle during the turn.
The lacing pattern of a wheel won't keep a rider from sliding out on a sharp corner if the rider hits a bump, the wheel loses contact with the ground, and the rider is at a bad angle during the turn.




I was responding to Fredo76 whose post I find to be of little value and erroneous because he attaches benefits to something that doesn't inherently contain those claimed benefits.
If someone slides out on a sharp turn using a carbon rim and disc brake, there is 0 reason to think they wouldn't have slid out on that same sharp turn using a box rim with tubular tire and traditional lacing to a low flange hub.
Like really, what does the lacing pattern have to do with anything? Why would a low flange hub stop a wheel from sliding out in a sharp turn better than the hub flange height of a modern hub?...and speaking of, why is Fredo assuming the modern hubs aren't also low flange?


I think his post was bad and contained erroneous information which misdirects the issue and frames the type of equipment he likes in a positive light. So I questioned his comment.
But since you two have responded, I am open to underswtand hat I am missing here. Why would a low flange box rim 3 cross laced tubular wheel not slide out in a sharp turn? And if that can be answered, then this can also be answered- why do carbon rim tubeless wheels with disc brakes slide out in that same sharp turn?
I mean the rear wheel losing traction in the fashion that motorcyclists call a "low-side" crash, without sand, gravel, rain or oil present as an obvious cause. They just seem to me to happen more often on disc wheels, with my woefully inadequate sampling consisting of watching a couple of team time trial stages and being surprised by low-side crashes, as if someone had rolled a tire. I don't know the reason they would be more common, technically, and so supposed what might solve it - older equipment, because I don't recall it happening much before disc wheels. Just a guess, not an engineering claim.

And my conclusion stands, regardless - not crashing is faster than aero.
