Power2Max is the only crank-based powermeter that can give accurate power readings with eccentric chainrings.


You can be fairly certain that the Rotor Powermeter is accurate with oval rings also. :mrgreen:

You're an optimist. My conversation with them @ Interbike wasn't promising. But I was just talking to one guy. Perhaps they've gotten enough cadence ticks per half-pedal-stroke to still handle non-uniform cadence such as is encountered with eccentric rings.

From what I've been told the Rotor unit isn't too reliable overall.

DJ- to whom are you referring to in your post? Power2Max or Rotor?

While checking on some other items I noticed that QBP has updated their listing for the Garmin Vector. They have removed their disclaimer which previously stated that there was no estimated release date and are now showing an estimated arrival date of 12/31/2013. That date doesn't match up with the rumblings heard recently, but the removal of "no estimated shipping date" is a plus.

The MSRP has also been updated from either $1499 or $1599 (I can't remember which it used to be) to $1699.

I guess we're back to seeing what is announced at Eurobike and Interbike seeing as the rumoured announcement date of 11 July has come and gone. At least there are murmurs again rather than almost complete silence.

On another forum someone posted that he got an e-mail from his LBS offering to "pre-order" the Vector with a delivery mid August. He also stated that initially there will be a only a small number of sets available, e.g., 3 per LBS.
Did someone get a similar notification and can confirm (part of) this?

I was referring to Rotor. With eccentric rings you can't rely in cadence from a magnet or one or two reed switches per revolution.

Neither of which are a problem with P2M

They've been testing the heck out of the thing. They don't want a repeat of the error other systems have made, which to release a half-baked product into the market, then try to clean up the mess.

For all the "first to market" fuss, I've not seen much of the Polar-Look system in the wild.

At least Stages got itself out there.

It could be argued that the Stages is in the "released too soon" category.

Is this
- a ("WA") guess
- an educated guess
- based on actual (insider?) information?

Or in other words: would you buy it
- as soon as it is available?
- as soon as there are some (positive) 3rd party tests?

I'm asking because I'm interested in buying a new "toy" (soon... -- and for those telling me there are other PMs already available: yes, I know, and I have some already).

Yup. On the one hand, they made those changes quickly. On the other, that the changes were achievable so quickly meant that they had not tested the units adequately before release.
