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

Probably none but he was raking in the 5EU primes back in the day :P

didn't he start as a time trialist?

what always gets me in those bunch sprints is that you need to do very high power for a minute or two prior to the sprint. very curious what is 1-5min power is.

didn't he start as a time trialist?

He did. He was twice World Junior ITT champion, and finished third in the 2010 u23 World ITT, behind Taylor Phinney and Luke Durbridge, and beating the likes of Rohan Dennis and Tom Dumoulin. He turned pro based on his TT abilities, but then Skil-Shimano noticed his sprinting skills at a training camp and turned him into a sprinter. He won 17 times in his debut season, including a stage of the Vuelta.

If you remember this and aren't just looking up pcs then I wonder what you're not remembering?

I can never remember which way to loosen pedals.

I looked it up the other day, as I was getting annoyed by idiots claiming Kittel's power numbers were akin to your average UK first cat. That 2010 u23 race stood out in terms of the quality of the field.

So to align my crank pm with my Wahoo kicker I’ve usually run both when doing a ramp and adding the crank value to my head unit for riding outside.
Is there a better method?

Haha, you loosen both backwards, towards the back of the bike. I have to learn stuff like that because working on bikes makes me rage so if I got it wrong I'd end up just hammering the cranks off with a cold chisel and jumping on the frame to teach it a lesson.

I'm sure half the people dissing pro power numbers see 400W on their headunit for 10s and think "yeah, I can hit pro numbers, i'm a legend".

Test indoor and outdoor, indoor and outdoor?

I use my indoor tests for indoor training and my outdoor power for outdoor racing. I don't really test outdoors any more because I don't feel a need to. I know if my power is up or down for a certain activity/duration and I can either increase it or not.

Everything has changed since Covid anyway and my indoor numbers last year were for the first time higher than outdoor. But what does that mean? Not much, it just means I got better at riding indoors. It may have translated to better outdoor power but I only raced once and my power was down - but that could've been for any number of other reasons.

tl;dr I should've bought bitcoin instead of powermeters

Ha
Indoor test. For riding outside but not racing just so I can pace efforts on climbs and TSS scores without having to do mental arithmetic.
My crank power meter reads slightly higher. Maybe I’d insignificant one the scheme of things

cold chisel

Very aussie that!

Hi!

It was very tongue in cheek but I appreciate that doesn’t always come across in posts.

It wasn't on here, so it wasn't you.

Ha, I didn't even think of them

I remember using my old man's to smash fuck out of lots of stuff in my youth.

Stuck? I don't think so. You're just not hitting it hard enough.

It's only going to be small % though, unless something is way off. So you're still training in the right area. If it reads higher outside and you're trying to hit indoor numbers you should finish a workout or interval knowing it could've been done harder, I'd just pick a power value slightly higher and ride to that, ie. if you're doing 4x10 @400 but you feel you've gas in the tank because your cranks are reading wrong, do them at 420. You'll soon know if that was the right move or not :) Or, for something completely different, stick tape over your headunit and just ride them where you think and then analyse the results.

But your question was calibration so unless you've got temperature compensating power curves for both units and can apply them live I think you're wasting your time worrying about small differences in accuracy.

Pffff - I know cat 1 riders who are about 4.9 W/kg. Admittedly they can’t put out 2000w.

lol people love to exaggerate power

i just remember away from the direction of rotation. otherwise i'd probably have pedals cranked on so hard i'd have to buy new cranks to change pedals

SRAM have now bought TIME pedals so they can destroy ATAC as a pedal system maybe produce Quarq power pedals

SRAM have now bought TIME pedals so they can destroy ATAC as a pedal system

Surely ATAC is perfectly able to destroy itself, by achieving practically no market share. Same goes for the road pedals. SRAM have got by without a line of pedals since the dawn of time, with the exception of a couple of Truvativ flats from downhillers, so I'm not sure why they need Time. Very unlikely to be as a basis for power pedals as they just killed off Powertap pedals.

Power ATACs would be nice, but I don't love this on balance. Sram will control retail pricing much better than Time did as well.

Fucksake.
First they came for my Powertap
Then they came for my ATACs (ok, I haven't ridden them for 10 years)

The calibration numbers on Quarq Dzero gxp have suddenly jumped up by 100x and it is now failing to send power data. Has this happened to anyone before? I've followed the troubleshooting reboot advice but it hasn't fixed it.
I'm expecting it is has died an early death, it's out of warranty but is there a repair service?

Have you tightened the 2mm Allen bolt that holds the battery holder/contacts in place? You have to remove the battery to access it, but mine stopped working and some research suggested this might be the problem, although I didn't have the calibration issues but this is usually a symptom, and once I did this everything started working again. It seems it can loosen from vibration over time.

This happened to mine. I was riding along at normal pootling watts and suddenly it was reading >1000w. Shortly after it died and never gave any readings ever again despite trying all Quarq's suggestions. It was just out of warranty too, but they eventually agreed to replace the spider. Reluctantly. I made a donation to their preferred charity as a good will gesture.

Thanks both. Doubly annoyed that not only has it broken and that GXP been discontinued but also that the replacement dub version is out of stock with 165mm cranks...
I'll contact them on Monday and see what they say. Hopefully they'll offer something.
