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

I've an old Powertap Pro with G3 Internals that is now giving me some random 2000+ Watt spikes.

This doesn't happen every ride, minimum cost to have it serviced/calibrated is £160 or so, which for the age makes it pretty much a write off.

Is there anything else that can be checked at home? or is it knackered.

Mine has done similar things when the battery is on the verge of dying. If you haven't tried it already, a new battery might solve it.

Depends how much it is doing it. I find it easy to correct the odd spike in WKO but if there's lots of them I would service/replace it.

Does anyone know what's a fair price on a 175mm Quarq Elsa rs with 50t 9000 chainring, 53t 6800 and 39t inner? No BB, new battery. I can't see any that have sold recently

£350 posted?

I haven't trained with power for a while, but thinking about looking at numbers again......is there still fuck all powermeter wise available for a Cannondale SiSL2 crank?

edit - pedal option maybe?

Loads of options. SRM, P2M, Quarq, Stages.

Op, maybe not Quarq.

Yeah, want to keep the SiSL2 chainset.

Used Quark on a different bike and had powertap wheels

Just looking at the Favero Assioma Duo pedals

Interested where you end up with this - I have a similar question with my new look which has the all carbon zed crank, so my existing crank based PMs don't work.

I guess pedal is the next thing to look at but it means moving away from my beloved speedplays...

The Garmin Vector 3 is highly rated by DC Rainmaker.

I've got an unused set to shift @andyfallsoff if you are in the market...

Thanks both.

@onyerbike - maybe, how much are you looking for?

@YaniKani has those

Faveros are workhorses, swapping between bikes without a problem for about 2 years now.

Thanks, I’ve only ever heard positive reviews for them

I was going to stick them on the 'bay for £500 (dual sided).

I am realising they're more expensive than I thought... Am out (for now at least), need to decide if I want to invest that much in this bike.

Whatever happened to power meters getting cheaper!

I got a Rotor Inpower chainset for £150 on the ‘bay 😚

Yeah, I've been buying relatively cheap Powertaps for years.

I only bought the Qarq full RRP because I couldn't be arsed waiting for a bargain crankset.

Crank ones seem to be, sad this pricing hasn't trickled down to pedal based meters....

Cheap cranksets come up when people upgrade to pedals.

Wish Wahoo would get on with developing Speedplay power pedals, then fast-track depreciation and market saturation so I can get them for cheap on ebay.

To be honest if the look didn't have the proprietary all carbon cranks, I'd prefer crank based... Seems safer from damage than having the most expensive component sticking out at the place most likely to be bumped into.

And I wouldn't have to use look keos...

Agree speedplay would be ideal!

Never going to be cheap though are they - niche within a niche.

And a total nightmare from an engineering perspective.
