The look power base pedals seem to take quite some time to setup properly.


The stages unit I have (SISL2) takes about 10 minutes to swap between bikes. That's doing everything properly with a torque wrench, etc. It would be interesting to see how much time it takes with the Garmin pedals. I assume the pedal pods add a little bit more complexity than your standard pedal swap.

Even if it is a bit more complex, the big advantage I can see with the pedal based units in terms of moving between bikes is they are universal. The stages unit only works if you have the same crank across bikes.

The likelihood of an issue with a pedal swap is less than the likelihood of an issue with a crank swap. Less "stuff" to go wrong with a pedal swap.

And if they make your crank arm.

Vector finally drops. $1700. Yawn. Don't see the point now.

Also can someone more knowledgeable than me tell me if my logic is flawed:

If the left pedal sends data to the right pedal, which then sends it to the head unit, isn't there some inherent delay in the left pedal reading? Could there also be bias introduced like stages has?

You know radio signals move at the speed of light right?

What kind of delay would that cause?

The UK pricing is pretty awful (£1349). It's almost twice as expensive as the cheapest power2max (~£720). I'm waiting to see what the BB Zone is like, but so far it looks like it's a power2max in 2014 for me.

With supply initially limited, they obviously want to open with.a price which allows some recoup of development costs.

DCRainmaker.com has an excellent review. Data look really good. I'm not surprised.

Key thing is initial calibration takes some time....not hop and go, exactly. Also it won't work with the recessed pedal holes of my old Lightning (new Lightnings have flush pedal surfaces).

Since I'm recovering from a right leg injury, these would be most welcomed.

I was really excited when vector was announced, seemingly decades ago; it's a system that seemed to make the most sense for ease of use, transferring between bikes, not limiting wheel choices, and the price was below crank based systems (I think it was originally introduced at $1200 US or so?).

But after seeing how poorly launched the 510 and 810 computers were, I just don't even want the hassle of potentially being Garmin's guinea pig. And with the now higher price, vector is even less attractive for a package that doesn't give you anything other pm's can't. Odds of breaking or damaging a crank based system in a crash are a lot less than pedals. Given the price and the improvements that the new comers to the market are making, power2max and even stages are looking pretty good.

As soon at the new carbon Tune cranks are out (and assuming they are not noodles and also assuming they have the same spider as the Smart Foot) I think the Power2max + Tune carbon setup wil have to find it's way onto my bike.

Guess all of those vaporware comments will finally have to be taken back.

Using the first 10 km of Ray's "solo mountain" ride, here are the gear ratios imputed from speed and cadence (we know the accelerometer cadence from the Stages in its initially released version was noisy but has since been cleaned up by firmware update). The x-axis is distance in km, the y-axis is imputed gear ratio. I've left off the names. Which was which?

If not spending hundreds of dollars on a technology you invented takes away my status as a serious cyclist, I can live with it.

His point is that Stages isn't good enough to pick up differences in power associated with position changes, or for that matter, likely fitness changes, since there's always the question if the power difference came from a change in L-R balance. But for pacing, it's likely fine.

And my point was that, after riding a quarq for ~12k miles last year, and a stages ~7k so far this year, with a lot of interval data, hill repeats, TT data, road racing data up on training peaks to analyze, it's working just fine to track my fitness gains.

But that's admittedly anecdotal. I'm one person (who doesn't happen to be associated with the bicycle industry).

Edit. sigh :-)
