    Very interesting..... my little biomech mind likes to see dots and force graphs!

    "One interesting result of this pressure mapping was the realization that the highest points of pressure do not correspond to the sit bone structure; cyclists do not sit on their sit bones."

    This is sort of what I was thinking on my last ride- trying to find where I belong on a road bike still- and whenever I thought 'wait, I have to sit on my sit bones', I'd tuck my butt under and be really uncomfortable. Instead, I wanted to tip my pelvis forward a bit (this of course makes me remember that my current saddle squishes my girly bits, but that's another issue). I can't even imagine actually sitting on your sit bones in the drops and sure enough, they're graphs in the drops show the huge increase in pressure, especially in the ladies, when you go into the drops. Also, I still think the sitbones should be supported even though we're not always right on them. My only question from this would be is the SMP design more what we need- the pressure seems to be all centrally located, maybe because we have round pelvises and saddles tend to be flat?? I'd LOOOOOVE to see similar graphs from Selle on the SMP to see if they get a more even distribution of force in the entire 'cup' shape. They have quotes that it proves good circulation, but don't show the pressure proof.... which usually means it isn't there. I'm very intrigued nonetheless as a biomechanist and as someone who hates their current saddle!

    PS- there's an article in last month's Medicine & Science in Sports & Exercise journal that has similar pressure data from a Bontrager Race and Fizik. If anyone wants to see it, email me and I'll send you the pdf- it's one of those journals that requires a subscription so I can't just link to it.
