I've just found out about this rather nifty bit of kit :
http://quarq.us
and in particular, it discusses the wireless 2.4 GHz protocol ANT+Sport that it will use, and that Garmin uses.
I have a PT SL 2.4, and it uses the same HRM strap as the Garmin, and sure enough, it has an ANT+Sport logo on it. This would suggest that the Powertap hub may also use that protocol. Why is this interesting? That would mean that the new Garmin 705 GPS might work with the PT SL 2.4, and also the quarq computer (they call it the qranium) might work with the PT hub also. This would be pretty good if it was the case, as I wish the PT computer had the features of the Polar S72x series (alt, temp etc), but this unit looks to have almost everything one could want. Added to track-compatibility with the quarq power sensor and you have a pretty versatile set of power measuring tools for road and track without SRM's hefty pricetag and clunky software. I've grown rather fond of CyclingPeaks WKO+ despite its one-PC licence (I have a laptop and a desktop, so I need two licences? Thievery!)
So, does anyone here know if the PT SL 2.4 uses ANT+Sport for its hub transmission? Saris haven't replied to my email yet (it was only 8 hours ago and we're in different timezones .. ). I'd be quite suprised if it didn't, as they are using that protocol for the HRM strap, and it would make sense to use the same protocol for both. This also raises some interesting posibilities with cadence (and speed, although with a properly calibrated PT, speed seems to work reliably, unlike cadence ...) sensors from other manufacturers, if they all use ANT+Sport we can pick and choose more suitable sensors for our bikes etc.
