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

I had it on the gravel bike and managed to knock off the cap one time during a gravel event. Was a bit more careful after that. Now it's moved on to the Talbot roadie, so no issues there. They do sell replacement caps though, right?

Yeah for 5 quid a price.

After I lost my second I emailed and complained, they sent 3 FOC. When I went to fit I realised I'd had neither of the plastic clips.left.

I was going to either use a little sugru or glue to try hold it on.

Yeah for 5 quid a price.

And 10 quid odd for shipping.

Pliers? Fingers, bro.

For getting the little rubber bungs over the battery cover bolts out? 'spect.

Yeah, fingers. You just push the edge up, grab it and rip it out.
I hate using tools when I can use my fingers (ooh nurse) :)

P2M finally responded to me... I accept it broke, but really its a bad design for MTB, said I can pay for replacement. The issue is the powermeter now doesn't send power data. So I am left with a paperweight.

Sorry, but this is not repairable.

You have two options:

1. You send it back and order a crash replacement , here you have to pay 290,-€ add. shipping for a new p2m system.
   Please have a look at:
   
   

If you are agree:
Please send the power2max (without chain rings and crank) to us and also please fill out and include the form attached. The delivery address is:

Saxonar GmbH
Hauptstraße 54
02906 Waldhufen/OT Nieder Seifersdorf
Germany

1. You try to fix with a tape or glue it with an adhesive.
   
   

Thanks for your understanding.

Pay for the replacement and then sell it on and get something else?

What is it? Something I could use?

If it broke once, it'll break again really. I could live without the plastic clips (thanks sugru), but it has stopped functioning as a powermeter now.

Post a pic? Interested do see what happened.

OK so I swapped the battery and now it works again. I didn't do this before as I only put a new battery in a few weeks back. I will monitor it, I wonder if it has a battery drain issue. Odd.

Both plastic clips snapped off. I reckon the extreme negative temperatures of kygyrstan (-15C) lead to brittle fracture.

Is this the result of crashing it?

If not, P2Ms response is, on a good day, disappointing.

I have fallen of, but I would hardly say I've crashed it.
I've slipped off on some muddy leaves!

The fact is, the design isn't really fit for purpose. If indeed you can break them as easily as I have (with small slips off the bike) then it's not really robust enough.

I can accept that snapping them off is ultimately my fault, and live with the consequence. However the fact the powermeter stopped working (now working again oddly!) was my issue with them.

I wouldn't. They know the types of conditions these things will be used in and should design accordingly. Doesn't look fit for purpose. If you've used your bike as intended and their component has failed in normal use, I'd ask them to do better than they have. Call them out.

Yeah I'd agree. I will see what they say, I did push back.

I have contact details for their head of brand, so I will try that, if I get brick walled.

I'll pick it up when I am back from Morocco.

Seems it's not popular with other people, for other reasons...

I watch 3 mins of that and all the guy said was it's fucked. No substantiation.

I swear more than most, but jesus.

His issue seems to be with the axle (FSA), not powermeter (P2M)

That guy might be smart and right, however he come across as mightier than though with apparent no desire to explain himself. Just shout.

That guy is very annoying.

His issue is that he applies the standards of the military industrial complex to bicycle components

I see his point at 3:30 about the spider 'lip' the means when the bearings are fitted, the spider is rubbing on the seal of the bearing, but I haven't got time to watch an hour talking about bearings.

He has however not read the instructions for the crank, being an arrogant fuck. If he had, he'd k ow there should be a seal between the end of the crank and the bearing which has a metal insert in it which prevents the contact he's whinging about. So that's user error by an arrogant twat, not poor engineering.

Who would have guessed that Hambini was an ignorant cunt?

Oh, those pink things. I thought they were just dust seals. Please comment this on his video :)

TBF I understand this is a design that comes from FSA and is implemented by P2M rather than being decided by them. I have the P2M version of the powerbox, and there is no lip. Funny, I was watching this video last night.
