Apparently Reed measured one with his ultrasonic wall thickness device, per 650b google group:

I was surprised to see that Reed’s measurements of the 2018 Masi showed what appears to be an 7/5/7 top tube and 8/6/8 downtube. I was expecting it to be 9/6/9 all around, because that is what is the best tradeoff in dent resistance and performance for standard 4130 tubing, which is what I assume they use. The lighter toptube (the 0.5mm part is what matters) should help the ride.
