I doubt you'll find any smoking gun to prove there are more crashes with deeper wheels - probably because it's not there.
The only argument I can see for having them is to allow companies such as Zipp to sell their wares.
Not sure how limiting wheel section reduces this.
That they are a wheel company and that they need to sell wheels to make a livelihood notwithstanding.
Given tests with the new rim designs vs old, V shaped, rims
What we do know is that high profile rims and wide spokes are susceptable to cross winds
I think it's accepted that deeper does not equate to worse in cross winds.
And like Murphs said, Ksyrim's are terrible in cross winds. Shouldn't they also be banned?
I also, anecdotally, found my Lightweights to be worse than my 6.7s in cross winds. The one that was worse would still be legal in 2014.
carbon braking surfaces are not immediate in their response time
Not sure how that relates to depth. This is a speed issue, not cross winds.
I think accepting that Pro's handling skills are indeed good enough to handle deeper rims is a pretty fair call. But I'm not going to try and convince you on what to believe.
