Pedal vs crank power meters
Discussion
Birthday coming up- thinking of getting a power meter for my road bike.
Bike uses a BB30 bottom bracket with FSA cranks. The only LH crank direct replacement seems to be the Stages FSA Energy one, have seen the G2 for £299 and the G3 for about £450. G2 appears to have various issues.
Other options seem to be the FSA powerbox (heavy and needs an extra £50 to unlock the Bluetooth option which annoys me), Quark Dzero (~£500+) or swapping the chainset to a Shimano 105 with adapter cups in the BB and go down the 4iiii route (adds more ££).
However I'm not sure I want to commit myself to the BB30 fitting as I will probably upgrade the bike at some point and don't want to be limited to BB30. So I've been looking at the pedal based options. cheapest and best value appears to be the Favero Assiomas at <£400. Easy to swap between bikes. Anyone with experience of these? Not really heard of Favero as a brand before.
Anyone spotted any good deals that would work on my bike?
Not fussed about single sided vs dual sided, just want to make indoor training more consistent (currently using virtual power on a Road Machine), do accurate intervals outside and be able to pace longer events.

I use these.

They are really rather good, and mean that I can fit them to any of my bikes, without worrying about crank fitment.
They are officially discontinued now, but they can still be found.

Using garmin vector 3. 2 bikes have different BBs so seemed best choice
Work well no issues. However looking to get back into off road so will either have to be happy without power data (a pain once you're using software to record training intensity) or get a specific meter for that bike

One thing to consider is pedals will eventually wear out, where as cranks do not.
You’d have to be going some to “wear the pedals out”. The bearings are pretty sturdy, and the claws ( the weak point ) can be replaced. My Vector 2s which I swapped between bikes now won't swap and I've needed to use an old Garmin headunit to calibrate rather than my Wahoo headunit. They now stay on the turbo/winter bike.
I bought a Quarq DZero for my 'best' bike and it's brilliant. Calibrates and syncs with my Wahoo headunit and gives dual side power readings.
I've not heard good things about the Vector 3s. My mate is on his third set and guy in my cycling club is at least on his second. Form over function by all accounts.

I’ve had no issues with them ( other than needing a reset on the fly, once ) and I know several other people that have had no issues either. Are you sure it wasn’t user error?
I know of 4 others that have had issues with P1s and all have received replacements. One of them is on their fourth set. I got a refund after a warranty replacement set lasted 2 weeks.I've got single side Garmin Vector 3's and since getting the updated design of battery cover they've been flawless in 5,000 miles and all weathers.
Connected to a Garmin Edge 1000 and means I can switch between bikes in seconds.
They read within a couple of watts either way vs my Tacx Neo.
My only complaint is that they use Look cleats - which seem to be made of cheese. Between two pairs of shoes / two bikes I've gone through 5 new sets of cleats in a year. I previously ran Shimano and got at least twice the mileage out of them.

Re cranks, you can get all manner of adaptors theses days to make most cranks fit most BBs. I run a Quarq DZero in GXP format on a Specialized OS30 (BB30, really) with no bother.
I have a Quarq DZero BB30 on one of my bikes. It has been flawless for the last 18 months... The only thng i wish I had known when I bought it is that the GXP version is more versatile as there are more adapters that would allow it to be moved to another bike (I believe I could have got the DZero GXP version and used an adapter to fit the BB30 frame).
On my new bike which has SRAM AXS I have the Quarq/SRAM spider based power meter.

This is exactly what I did. My Parlee is PF30/BB30 and I run an adapter with a GXP DZero.
