Ah good, that paper mentions Jim Papadopoulos. I did a small experiment with him back in '95 on perception of weight on the frame. Looking at that paper, I've got a couple of comments: 1) I'm not clear where they're getting lateral forces when a bicycle is cornering, unless the rider is hanging off the side of the bike motorcycle style. (which is generally unnecessary as bikes have enough clearance to corner at ~45 degree lean angles). 2) It's unfortunate that they didn't instrument a trailing spoke as well, so that they could disentangle the torsional strains from the radial strains. 3) While the tangential/torsional strains are high, it's not clear what the loaded zone is there, nor how much energy is being stored in the wheel due to power pulses. I suppose I could pull out my old FEA model and port it to see.
