I would be happy to, but please explain again the part you want to measure. I'm not sure I follow. Are you wanting the width behind the nose? And if so, how far back from the tip of the nose? Or have I misunderstood completely?
I do find the Diva to be pretty flat across the back.
We may have the same problem. I definitely think my saddle issue lately is due to thinning tissues and padding loss. I never had this problem before with the Ldy saddle and same Sugoi shorts. Now, those saddles are like torture devices! The only thing I've found that helps is Gold Bond lidocaine cream, but it only numbs the area for 30-60 minutes, so on a 2.5 hour ride (my usual), I have to reapply a couple of times; not too convenient!
