Specialized Alpinist Stem - Clamp Area Width

[Mr.Appa]

Has anyone purchased one of the newer alpinist/roval stems? Or have access to one to take a quick measurement?

I'm curious about the width of the handlebar clamp area - I have a set of handlebars that have a 90mm clamp area and want to confirm I'll have enough space for this stem and some clip-on aerobars. Specialized customer support is, uh, lacking at the moment...

Thanks in advance!
