One more point: the Vector is actually two power meters, one for each pedal, while the Saris is one. In principle the Vector could be run one-pedal-only, but realistically I don't think this makes a lot of sense.

Rather than offering complete pedals, Garmin could offer just the spindles of the pedals with Vector PM. It would a be more work for the consumer, but it would save Garmin getting into commercial arrangements with various pedal manuafacturers.

By huge, I meant a big deal or a big difference. Not that it's physically huge compared to one of those overweight PT hubs!

Poor choice of works on my part.

Ha! I guess it is so good it needs to be posted 3 times. Lol. No it is more what happens after little sleep and thinking I had read all of the posts on the previous page.

Looks like promising stuff. If it works reliably, and is ANT+ and is targeted at a pricepoint to undercut most other PM's, it sounds like a winner to me. The design also looks quite compact. if and when...
I feel like the Polar PM is heading for a misshit. Personally I have zero interest in it if I have to use any of those Polar head units and am limited to which software I can use it with, and reading the comments on various boards, i sure am not the only one..

The reason that I look forward to the Polar meter is their software...
And I'm not sure that Polars decision to wait for bluetooth is that bad.

If they manage that one you can use any smartphone etc.
And suddenly ANT looks pretty restricted.
Max Gravity, unfairly treated by gravity!

Very slick. Although it is telling that there wasn't even a working prototype at Eurobike. Fun to see who wins the race between Polar/Look and Garmin/Metrigear. Personally I think G/M has the edge, so to speak, being inside the spindle versus P/L being on the spindle, but perhaps the difference is small. The real advantage to G/M is not being married to a particular pedal brand.

do we know how much one of these baby will cost?

Im curious to see how the issue of Calibration (actual calibration, not zeroing torque) will work with this system. Doing it at home seems like it could be a serious pain.

Would you have to calibrate the slope on each pedal? Would you calibrate one pedal, which would "speak" to the other pedal and go from there? It seems like either way the potential to mess up the slope and get inaccurate data would be much higher than that of and SRM or Quarq

Since the Metrigear/Garmin pedal can report force, it's fairly straightforward to check that the force as a function of angle is good. I am not sure to what extent it would allow users to "calibrate" it. I suspect that's something the factory will handle, since the piezoresistive sensors in the spindle aren't expected to drift, the only reason it would go out of calibration would be that the pedal spindle's characteristics change due to damage. Speedplay X-series spindles, for example, can be damaged when X-series cleat springs come into contact with the spindle due to wear. This isn't a problem with Zero cleats, which I've been using with X-1 pedals without issue. I don't think Look pedals have this issue, however.

But you ride your X pedals with Zero cleats? No probs? Why the move from one cleat to the other?

I have one bike with X1's, then I was given some modified Zeros to try by a friend, which I installed on my other bike, and swapped my cleats to Zero cleats. I forgot about the cleats and hopped on my X1 bike and it all worked fine. The Zero cleats are just all-around better: less prone to wear and to damaging the spindle.
