OK, need to see DCR review this.


First off, it needs to work with a Garmin IQ app. The mandatory $250 computer is a deal breaker.

So, it's really a nearly $400 powermeter b/c the head unit has to be purchased as well. Trying to do some clever marketing???

I am more than a little bit skeptical about this method of estimating power... Also I wonder what kind of drag that little thing has as it's speeding over the top arc of the tire? Will it fit on a disc wheel?

But kistler makes the best pressure transducers so I'm certain it gives spot-on tire pressure!

It says you can use a smartphone running their app. So if you've got an old phone laying around, you're good to go.

But yea, I'll wait for DCR's review.

I've been thinking about this for a solid five minutes and my best guess is that they're using the tire as a strain gauge. That's clever. I might believe their 2% claim over the course of a ride but over something like a 1-minute segment I doubt they're 2% accurate which kind of defeats the purpose if you pace with power.

A product has to be really bad to get fewer than 2 stars from road.cc, but this one did.

He has talked about it. It is number 5 here

Also the $250 price I read as device plus computer.

I actually use many Kistler products at my work and they are some of the best products available, but...I don't know how accurate their algorithm can be.

As long as it's consistent it doesn't matter if it's off by a few watts.

I'm putting one on my car tires. Hello Zwift!!!

WatTeam has announced a single-sided version of the Powerbeam for $259 Retail. The aesthetics leave a lot to be desired, but, ignoring, for the moment, the limitations of the single side design, it promises* to be more than accurate enough to be an effective training and race-effort-management tool.

So, for $129, you can get this powermeter which isn't remotely accurate, and, even if somehow future miraculous firmware updates made it accurate, could only be used with a proprietary cycling computer or a single app. Or, for $259 (should be able to get it for closer to $230 with easy-to-find 10% discount codes) , you can get a real direct-force power meter that actually does work, and can communicate with pretty much any popular cycling computer and training app. Not much of a choice, IMHO.


*"Promises" based on actual performance of previously released versions of the product, not just fluff rhetoric put on a website by some marketing flunkie.
