Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

You guys.

The members of Team SKY who are in Australia to race as still using SRM, from the pictures of training rides.

Invented WiFi. Your argument is void.

It's all about 4G these days.

4X is better.

So if the retail version of Stages is left arm only is there anything actually stopping them putting a sensor on the drive side as well for Sky?

madness.

Chainrings and heels I suspect. Unless they radically redesign it.

I thought stages made a replica nds arm. As opposed to just inserting their gubbins in an excisting arm. So making drive side versions to similar quality as DA would be abig ask.

Nah they use OEM NDS arms.

^what he said

I was hoping to buy a Stages once they've got some stock in the UK. What are the fucking chances now, every MAMIL in Surrey will be after one!

I wanted Stages before they were cool.

Ha!

Though I'm not sure a powermeter ever constitutes 'cool'.

You can't get them in North America at the moment, let alone here.

As above, they retrofit them to existing arms that they buy direct from OEMs.

You could probably squeeze one on to a Hollowgram DS crank as is, but then you have the problem that it would hit the derailleur cage...

I blame Brailsford.

ftfy

I'm not in Surrey.

Don't get...oh wait I do.

Very good...

I'm not in Surrey.

It was still worth it.

I've just been looking at lawnmowers, I couldn't get any more middle-aged if I fucking tried.

How many bikes do fit in your trailer?

I doubt that Stages as is, is accurate enough for Sky, but I don't know enough about power training to know if this genuinely matters. (My view, which I'm happy to be disabused of, is that as long as you're using the same product for all your power training purposes, then the actual genuine power figures don't matter, as what you want is consistency).

I would have thought they need to be able to translate between the two systems. I.e. sky train grunt #2 was producing x watts at this stage last season on srm now he is producing y watts with this new meter. The question facing brailsford et all will be; Is that because he has different fitness levels or because they changed the measuring tool from srm to stages?

I'm sure they will have been doing plenty of testing and wouldn't be using them if they didn't think they could get the required data. Couldn't you run stages at the same time as SRM and get direct comparison?

Also you would expect the SKY team to have pretty even pedalling so measuring one side and doubling it should be fine. But saying that I reckon they will be developing a double sided 'Pro version'

The guys at the tour down under are using last years bikes with the old SRM's on.

SRM also make most teams pay for their power meters which means teams like SKY will not have them on all bikes as the cost would be too great. Stages will be giving them for free and you could buy 4 stages power meters for the price of one SRM

Isn't right/left pedal power data just a gimmick anyway? Interesting to know, but not exactly essential information.

Couldn't you run stages at the same time as SRM and get direct comparison?

I would have thought a few hours on a turbo, doing sustained efforts and sudden sprints while having both fitted, would give the data need to compare a riders performance on each. They probably react slightly differently to temperature change too. So maybe get one of the doms to do a few stints at different temps.

Still not rocket science.

I thought the SRM love came from reliability. They dont claim to be any more accurate than everyone else in the game. So if Stages is as reliable. Why not.

You'd think so. I have no idea if the market is there. But Rotor and Garmin make a lot of noise about separating power out for each leg. Maybe its dersired data?

Power2max use a accelerometer to determine cadence. Something that attracted me TBH. It means the cadence data is constant, like the force data. As opposed to averaged over the time it takes the magnet to pass the sensor. Although if the PM is transmitting every second, and you pedal at a cadence over 60 rpm. Thats not really going to effect anything. Its just neater and cool.

But this means the P2M can determine where in the pedal stroke the power was created. It then separates this into up stroke, and down stroke, assigns the up stroke power to the left leg, and gives values for left and right power. I'm at a bit of a loss as to what to use this for though. Plus as a SS MTBr. I have a habit of pulling on the upstroke to compensate for poor gear selection. Which will muddy things somewhat.

Anyway. The transfer to P2M is sent, and I am excited. Although I've blown my Xmas presents from my entire family, as well as many months of bike budget.
