Thanks Eric. Another group member tipped me off to this photo from the article, but I couldn't quite make it out. Looking at it now I think you've deciphered it. If this is the final capacity - and I'm guessing it is if Riv went to the expense of having the boxes printed - the current 3x drivetrain on my Platypus will exceed its specified max chain wrap. I may have to wait for the Sam Hillborne I've been contemplating for my next birthday. If I hear anything different from the inquiry I finally sent Will at RBW, I'll share it here.
