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

It's nearing full winter up here. I'd rather wait untill the roads were unridable. But I'll email them.

Yeah took 12 working days from when it arrived there to get back. So wait a bit.

Apply the danstuff principle and buy another so that you are never without one.

didnt you just replace your nexus screen!?

Just in case:

It's a piece of piss. Takes 2 mins max.

Ha. True.

I was just whinging because it was on my list of things to do last night (only night this week I had free of training or life stuff) and it turned out that in the 4,000 screwdrivers I own, I didn't have the right tool to do it.

I only had a weird multi driver at hand.

Didnt fit in the hole.

Decided I'd modify it using a big sharp camping knife.

Then it fit.

Then i found my electrical screw driver in my jacket Pocket on the way to the shops directly after finishing.

This is my standard way doing Things though.

Only one?

Getting some drop-out whilst using my SRM + Garmin Fenix 3. Cadence and power showing blanks.

Not sure if it's magnet placement because most of the time everything is working fine. Then it drops out for 20 seconds.

Next step is to try everything with a different head unit, try and isloate the problem.

That's the exact problem I was having with mine- I sent it back to SRM for to make fix.

Yes - bit of a bummer this as it's just come back from SRM. Hopefully it will play nice with a G500 or PC7.

If not...well, I'm not having much luck at the mo.

My experience was that it was the unit, and that it was across all head units (therefore).

Might just be a wonky magnet, that said.

I can't understand how it could be magnet - as it works for 95pc of the time. I'll do more dicking around with it tonight tho

Why would the magnet affect the power reading? Thought it was just for cadence?

Powermeter won't send power if it doesn't think it's moving - no cadence=no power.

Otherwise it'd display 300 watts whilst trackstanding, as there is torque (aka weight) on the pedal.

you need to know cadence to calculate power.

The SRM strain gauges measure torque and torque x cadence is proportional to power

Building on this however...could it be some weirdness caused by using a GSC10 speed / cadence sensor?

I'm not using the gsc10 cadence magnet, so it won't be reporting cadence as far as I know.

I guess it's possible.

Mine tended to do it (or, rather, I noticed it) when (for e.g.) booting it over Waterloo bridge - so periods of high power when you would like an idea of what you are going to have to hold onto.

It was mega frustrating when it was happening to me.

Looks like it's Fenix 3 related. Wonder if it's a range thing. Will try watch on other arm.

Well that's good news.

Another buggy Fenix?

I'm a bit shrug too.

Things it could be

Range
Processor overload
Noise
Combination of all three

Will simplify set up and try again.

First ride with the Pioneer today, did what I expected, bar the 1,800 watt spike but Training Peaks auto-nuked that.

47/53 split.

Fenix lost the powermeter when I stopped for a coffee, but I'm aware of that foible now and re-scanned and therefore re-found it - that's fucking annoying though, and means that a Fenix is total shit for a triathlon as you'd need to re-scan whilst jumping on the bike.

Considering selling my Vector S. Would anyone be interested? Great condition, just moving parts around..
