Nevermind. I can't read.

Saw it in an Outdoors magazine, priced at $2500.

Over/under on sales of those pedals with that price point and a proprietary data format? I'm setting it at 9...pedals, not 9 pairs.

Stunningly stupid. Polar seems to be determined to fail in the power meter business in every way possible.

The target appears to be sub $1000.

Garmin wants to sell head units to the masses, and part of that strategy is to commoditize ANT+ power meters. Sub $1,000 and they open up entire new markets.

Sub $500 would be better, but that's likely a few more years out.

If Garmin gets to market Fall 2011, Polar/Look is toast.

The Polar system is not ANT+, has a ****ty head unit, is heavier, and cost way too much.

Desperate attempt by Polar to be relevant.

If Garmin/Vector doesn't play out, Polar gets a small perecentage of market share from Saris, Quarq and SRM.

Garmin/Vector comes out with a sub $1000 viable product, the Polar system is a footnote in history.

But it is very intriguing vaporware from a major established company.

Sooner or later, somebody will market a sub $999 pedal based power meter that will clean the SRM/Powertap clocks.

I say sooner. Within 2-4 years.

So can anyone confirm that Garmin Cervelo was using them at TdF? I didn't hear a peep out of anyone, so I'm guessing that's a "no"?

Dying for *any* news on these...

The_Cretin

For now, I'll just have to make do with my Chinese knockoff SRM which costs less than a normal Dura Ace crank.

Looigi

Info please...

You know, from an engineering standpoint, I never understood why power meters didn't begin in the pedals. When I first heard someone ever mention a power meter, I assumed that was where it was implemented.

And the whole price thing -- its just like Apple products -- they just charge that much because they can. There's nothing too new about it and load cells have been around FOREVER. I'm seriously considering building my own set with the help of an EE I know.

The pedals are the most complicated (instead of looking at a single torque as on crank and hub based units you need to consider the force vectors on the two pedals and their component perpendicular to crank rotation) place to measure power and have more severe space constraints than hubs and crank spiders.

As an engineer I'd choose the drop-outs - one axis to measure, easy to do a wired interface, no complex mechanical assemblies to integrate with, complete user freedom in pedal (SPD, Look, Time, Speedplay, Bebop, Crank Brothers, there are a plethora of choices), crank (various crank arm lengths, bolt circles, and ring counts), and wheel (aerodynamic, climbing, spare) choice.

As a marketing guy someplace other than a bike company I'd do something which can be sold as a retrofit in the form of a hub (the minimum viable marketable product is a single SKU that works with all crank lengths and BCDs and sells better than a crankset to people training on multiple bikes like dry and rain or cross and road)) or cranks (easier to sell to the racing market which wants multiple wheel sets).

Counterfeit Vaporware.









Now that's impressive.

Phantoj

lol, the eternal hubris of engineers...

Phantoj

The catch at the dropouts or chainstays would be dealing with all the road chatter noise in your signal, IMO...

Runner 1

Hubris? I'm sorry -- I didn't mean to come across that way. I always hate it when people act arrogantly online, so I certainly didn't mean to come across as the same. I was just attempting to provide my ideas on the subject (it was more of a "I wonder why they..." rather than a "They did it wrong"), although I'm sure other, more knowledgable engineers in this subject have already optimized what works best.

DC Rainmaker has an update:

I guess that's good news. Hardly the fanfare I was expecting at this stage though.

Or in otherwords...they couldn't get it to work reliably in time for the tour so they just went with their regular pedals

I still cant see how they will be able to make this work at all on third party pedals like speed play. A critical measurement to allow the calculation of power is the amount that the spindle bends under force. The strength of the spindle is known so if you measure the deflection you can calculate the force. In order to do that you need to know exacly where the force is applied because the same force will cause different deflection depending which side of the pedal platform is loaded or if it loaded evenly. Since the spindle on speedplay is tiny at the tip and not hollow right through you cant get strain guages right to the end so the information to know where the load is applied is not available.

You then need a high data sampling rate as your foot likely presses differently on the platform through the stroke which needs to be accounted for. That info then needs to be combined with extremely accurate speed and vector data. There are so many variables that I would think they would have to design their own pedals from the ground up to make it work. And even then its a tough problem.

The padals must be the most difficult place to put a power meter, at least a hub has plenty of space and only requires a single torque to be measured. Even these fail sometimes with only 4 strain guages - vector has something like 60 to give bad readings and they are all stuffed into a tiny space.

Good on em for trying - maybe it will work, but I wouldnt be surprised if they end up with product that is at best consistant rather than accurate

Vaporware boys. You can do bong hits of it.
