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

I'm pretty sure I don't want to look at a laptop whilst turboing, otherwise that would be good. That's more to do with the setup of the bikedungeon™ than anything.

I'll look into the Kurt trainers.

If I go down the powertap route... any idea at which point in their model history did they go Ant+ ? It'd be good to use it with a garmin.

I think (but may be wrong) that Powertaps went ANT+ from the SL onward, annoyingly if they update mine as part of fixing it I will no longer be able to use my Cervo, as that talks to the hub using a proprietary signalling which the G3 dropped.

You can have trainer Road on your phone. But then you need to get ant+ signals into your phone somehow.

So the Kurt thing is using a profile. Good info people. Thank you.

You can get a 2nd hand powertap wheel for £350 these days... Just do that and use it on your regular turbo. Means you'll have proper drivetrain power, not some simulated number from the wheel. Not fixed obviously though.

My fixed powertap wheel cost me £35o :)

From where?

The Kurt thingie is basically doing what trainerroad does. But sending it to your iPhone instead of a ant+ dongle.

Did 90mins of hill repeats yesterday. Power balance was 50.3 : 49.7

I have now decided this is a very important metric. At least untill my numbers look poor.

Doing the same 90mins workout in an hour. But with fatigued legs. Wonder if it'll change.....

Do keep us updated. Edge of the seat stuff.

Evans had a couple of Powertap Pro track hubs going very, very cheap a while back. I got one, umop3pisdn got the other.

So the Kurt thing is using a profile. Good info people. Thank you.

Worth reading the DCRainmaker review- although if you haven't got time for that (what I take from it is) he basically says that the speed+algorithm=virtual power providers are good, but lack the calibration function of the Kirk - so you go from an accuracy of +/1 15% to +/1 2%, depends on how much you value that accuracy.

I was reading it as you posted i think. :-)

It seems the kurt is accurate enough (though no better than TR).

I only use a fixed bike with a fairly basic trainer, resistance is magnetic but enough for everything bar sprints.

Repeated, seated accelerations are the only thing I'd like power for really. A track hub would do that just fine I think.

~£450 and no, G3 isn't in any way compatible with the older hubs.

Thank fuck W/kg isn't the be all and end all. :)

There's an aero chart kicking around as well that plots CdA against Watts.

Used Computrainer? Doesn't measure power but it applies a load of x Watts to train against.

@miro_o - Sigma Sport have the Kurt Kinetic Rock and Roll trainer at half price at the moment, if you were looking for getting more bang for your buck.

Cheers.

[edit] Kurt trainers come with a 'lifetime crash replacement policy' !!! [edit]

I spoke to Paligap, £340 to remove my borked torque tube and stuff a new one in there.

At least I could keep the hub-shell that would match the front wheel I suppose.

Godamn.

Oh dear

Ah yes I remember. Balls. I would love one of those.

It would also lose the ability to talk to the LYC, so that was a wise purchase.

Mwahahahaha!!! I have added mine to my extensive Powertap collection.
