Power Meters

Personally unconvinced by Vectors, of the 3 people I know that ride with them, all are constantly having issues. Stages much the same, but finally seem to have their act together now. Still seriously limited, and pricey for single sided.

Quarq, P2M and SRM are the gold standard in my eyes. Never heard any complaints with either.

1s or 2s? 1s are a bit more fiddly. But 2s have been spot on! Lots of metrics to go with them too which many of the others don't have.
 
All 3 have two sided. One of them had a replacement set from Garmin, but has pretty much stopped using them again given they've been so finicky.

I don't really buy the whole changing across bikes thing, I lived with changing my one PM across two bikes fairly regularly and it was far quicker than fiddling with and torquing pedals would have been.

Crank based solutions are just way more rugged, and just work in my experience.

What are the problems they are having with the Vectors? Mines are seriously spot on.

I don't torque them, decent pedal wrench off and on, re-calibrate and good to go all in 2 mins. I challenge you to a PM swap race... To the death!

Didn't mean dual sided meant the V2s.

I torque mine up but even then probably 5 minutes at most for the faffing. As I say the V1 mounting mechanism is a bit more fiddly.
 
Echo the above. Sell your existing chainset and it makes it a bit cheaper still. Servicing costs are cheap and P2M are very responsive to queries etc if you have them.

This will be the 4th one the missus and I have bought (all 2nd hand) and had no issues with any of them. It's proven tech by now and used by the pros.*

*Yeah, yeah I know Sky allegedly use Stages but there was a reason Kwiatkowski was aero testing round the velodrome in Mallorca with a disc wheel on his road bike...

That is a great PM summary.
Money no object = crank based / Quark Elsa system

I'm still happy with a one sided PM for half the price of the other dual system,

Great find that video. I was looking at the Quarq system, but I have heard so many good things about the Rotor cranks, I think I will go P2M when I buy a power meter.

As for the P2M using Praxis Works (or Rotor chainrings), I haven't really read about people having issues with shifting being worse. One person with Di2 just said that changing his chain fixed all his Di2 issues with Praxis Works rings.
 
Garmin V1s. Had them over 2 years now and no major problem with them.

But you do have to be cautious with firmware updates. Been on this type of forum I think most people like me treat FW updates with suspicion and never did the updates that trashed everyone a year ago.

So good but not for people who don't have much idea about what they are doing or are hamfisted and sloppy installing them.
