I ran across this fancy German headset which stops the rotation of your bars at a set position. The copywrite (see below photo) says it's meant to protect your top tube, but the other night Jake and I were talking about how perfect this would be for polo.
Instead of constantly jackknifing your fork when trying to make tight turns, imagine if your wheel stopped at that one degree before turning inward and throwing your from your steed. Eventually you might not even have to think about how far to turn, but just slam your bars to the right or left to instantly maximize (or should I say minimize?) your turning radius. So long as these are adjustable (from the design they appear to be) this style of headset could make a huge difference in bicycle polo.
"Have you ever in a crashed, and scratched the handlebars over your top tube or slammed the triple clamp fork into the down tube? Stupid maneuvers that scar your frame for life. That is the reason why we developed our Tr!cksatz headset which prevents you from knocking your handlebar.
CNC machined of aerospace grade 7075 aluminum, anodized, laser etched logos and with the best angular contact bearings available."

Now if I had an extra $150 to spend on a headset...
