I appreciate your videos Mike. It has been a while since I lived in Toronto. Which is your bike shop for getting this type of specialized high-end stuff, like Rotor power meters, in Toronto? Or do you order all your stuff on-line?
Thanks for the feedback! Since I do all my bike servicing myself, I usually buy parts online. And I use a few dozen different places inside and outside of Canada based on my needs. I’ve included links to where I purchased my Power2Max power meter and Rotor chainrings in the video description (thanks for the reminder to post this!). Your options for sourcing Power2Max and Rotor products are somewhat limited. For Canadian shops, I would say that Bicicletta.cc and Mariposa Bicycles have the largest selection of premium cycling products. Primeau Vélo out of Quebec has excellent customer service and prices, although their selection of premium merchandise is limited.
@@bikesbymike Thanks for your reply Mike. I will have to visit those shops when I visit my parents this summer. Back in the day, I used to get my stuff at Wheels of Bloor and Racer Sportif in BWV and Duke's (before the fire). Cheers.
The P2m still only reads one side power, it only calculates whats the non-drive power basically by software but not actual power output, unlike if you buy pedal based or ei rotor 2inpower.
I don't think that is correct as it is a spider-based sensor, not single crank arm based. The single crank arm ones use a mathematical formula to estimate power on the non-measured side, but that is a different system. It is advertised as offering "complete dual sided power metering." It measures power on both sides but the NGeco (unlike the NG) doesn't give you power balance figures.
@@bikesbymike again the only way you can get actual dual sided reading is if you have dual sided sensors, spider based is 1 sided measurement, sorry to break the news to you buddy.
@@pvelardeNP I’m not totally disagreeing with you, we’re just not using the same terminology. You are right that the NGeco does not measure power from both crankarms as does the ROTOR2inpower, so it can’t measure true L/R pedal balance. But it is better than a single crank arm power meter that only measures power from one leg and then uses an algorithm to estimate power from the other. The NGeco has the power sensor located at the crank-spider and the crank-spider feels the force coming from both pedals. Power2max does a good job of explaining all the different types of power meters on their “Cycling Power Meter Basics” webpage. They describe their crank-spider power meter as offering “…complete dual-sided power measurement and so captures the power output of both your legs.” Here’s another quote from that page: “Pedaling forces are transmitted through pedals, crankarms, chain and chainrings. As long as you use both legs to move you on your bike forward, forces from the left and the right leg will be transmitted to the crank-spider power meter.” They also go on to explain why their dual-sided power meters are different and superior to single-sided power meters. I don’t care about L/R balance, but I do want power captured from each crank arm. The NGeco does that.
very helpful. thanks a lot!
Glad it helped!

thanks , you have to use loctite or no ?
No Loctite.

@@bikesbymike Shane Miller explained this in detail on his channel, and also DCMaker.
