I went to taipei cycling show today and noticed a booth marketing Pioneer Cyclo-Sphere Power Meter, which combines trip computer, power meter and analyzer for pedaling efficiency. Apparently the version one has been on sale for a while. and now they are coming out with version 2 at much lower price (less than US$1900 for both crank meter and computer.) Garmin Vector seems to get a lot of press as a new entry in the power meter field, but apparently this gizmo can do much more. Very excited about this.
