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

There is a pair of 2nd hand vectors on Facebook for £600 being sold by one of the matrix-vulpine team I think. Not really a swap but not too bad a price.

Can fish link out if anyone wants?

Yes please.

Finally got around to swapping the battery in the G3 last night and the Edge 800 calibration said 235. Not so good.

It gave a decent wattage for about five minutes but then tailed off so the Computrainer ended up 100W up on the G3.

So, that lasted about 4 months whereas my oldest non-ANT+ one is still fine. Fucksticks.

Sorry, my guess is that they're gone already.

I'm 99% sure they were posted by Harriet Owen in the group "buy and sell cycling stuff in Oxford" but I can't find the post now. I checked my browser history and a couple of the FB links I visited last night now seem to be dead so I guess it's been removed.

So don't trace it back to power. Use time in HR zones.

Which tells me about HR, but I don't often log that- I always log power.

I tend to log hr on the turbo, and sometimes on a club run.

Have you considered just enjoying the rides?

I might be wide of the mark here... if you're looking to log work done you'll be doing that as TSS to keep your Performance Manager graph (or similar) useful?

You can do that with hrTSS and IME be within 10 percent per ride so long as it's a ride of a few hours (short turbo stuff will be off, as will short intervals).

I have done all my miles since November without a PM and I have to say that it's been really bloody nice.

Are you following the "break it, fuck it" methodology like moi? Fun times!

I found out my Vo2 max today. I'm waiting to get the numbers back.
Now what?

Success?
Profit?

Well, I broke down the bike that had Stages on at the end of November, still haven't gotten round to building it's replacement or putting a compatible crankset on the R5.

So.. no power (apart from the track). I've not really been doing much training that really requires a PM, but I will be starting to do so in the next couple of weeks. It has been nice to just go riding without looking at numbers, and has made me realise I'm pretty good at training on perceived effort now.

It's all a scam!

Always thought it was pretty irrelevant for most events. See 'threshold' and the mess that entails.

All true, however - one variable (and the one I'm most interested in here) is that I'll be around 1,600 - 2,500 metres higher up next week.

This is the ride I was thinking of doing: https://www.strava.com/activities/204283927

Last time I noticed that my resting HR was around 75 when I was out there, but when I got back (I was there for two weeks) it was under 40, although it soon went back up to mid-forties.

Essentially I'm interested in seeing the differences that altitude brings, and having both power and HR would be useful for that.

Fenix II - auto-zero enabled or not enabled? Now that I have an unfeasibly large number of Powertap track hubs, I'm trying to work out how to use them properly. And the Garmin 500 just doesn't cut it, given that I've not found a way of sending it back to firmware 2.80. And Mr. Garmin's response is, basically, Fuck Off, We Dont' Support 3rd Party Kit.

I see, that's definitely enough altitude to wreak havoc with... everything. Like you say having both would be 'interesting' to get an idea of how much to regulate your efforts (the opposite of de-coupling? ...re-coupling?). But even then you're just going to have to ride it in z3 and see what happens.

tl:dr

Fancy pedals won't help you if you can't breath.

What I found last time was that I could do a mid-tempo effort, but if I pushed even slightly beyond that it was like I was missing a lung.

Took a lot longer than expected to recover from a sprint/hard climb, also.

I'd be interested in looking at what I could sustain for say 5 mins/10 mins - that route I linked to has a couple of 20% pitches.

It's also fantastically beautiful out there.

Fenix II works with track powertap - prompts a manual calibration each activity, does not perform an auto-zero during.

You posted a pic from your last visit (I think) and it looked breathtaking. 2500m is seriously high on a bike! Have fun.

Muchos gracias. I'll stick to having one Powertap Joule GPS in that case. Anyone what a pristine and hardly-used Garmin Edge 500?

^^This was a photo I took on a run last time:

I switched to a Joule GPS, it's better in almost every single way compared with the 500. Way more customisable, and very handy when it comes to zeroing as it actually returns the live torque values for you.

Joule GPS

17hr claimed battery life sounds good. Does it have any kind of back-light for night use?
