Yes.


Dear Ben,

I _think_ that the idea is that yes, deep low-count rims are stiffer.

Stiffer radially, which they must be because they have a greater unsupported span. Not necessarily stiffer in buckle.

er, if they have a bigger section area, as they will be by being radially stiffer, they are stiffer in buckle mode too. moment of inertia.

Two different moments. Please try to keep up.

er, try not to avoid the relevant point! ah, but this is peter cole - what /am/ i thinking.
