Noob question about power meters

I’ve been using TR for about a year now to suppliment my on bike work for Enduro/downhill racing .

Given I do a couple of long rides a week, I’d like to see what kind of powers I’m putting down on these rides compared to what TR has me doing.

I plan to get a power meter crank, but am I right in thinking I will need to invest in a computer too? It won’t pair with my Garmin Fenix like other sensors?

If that’s the case, and recommendations for something small and out of the way, as I spend a lot of time bouncing off trees and the floor etc.

Cheers :beers:

Not all Garmin watches support power meters, but the Fenix should (which version do you have? You could check the specs/manual)


If you get a computer:

It’s possible to use a phone too if you carry one when you ride.

Like said above, it’ll likely work with your watch. Have a look into settings/sensors, and see if there is an option for power sensors.

With the latest updates from Apple, you can pair the power meter with you Apple watch too.

Seems I was severely misinformed. That’s what you get for asking DH riders :sweat_smile:

Looks like I can simply replace the left crank arm and pair it with my Fenix 6x after all.

Cheers boys!


Depending what crankset you have, it might not be that easy to find a left crank powermeter for it. Another option might be a spyder-based PM. Have a look for similar threads if its an issue.

If your crank model has a left-side PM option, then yeah, this is the easy/cheap option. Especially if you don’t care about seeing the data in real-time. If you want to see the power numbers while riding, there are handlebar-watch mounts, or something like a Wahoo Bolt with a stem mount works well.

Yeah that’s what I ended up doing. It was eye opening seeing what I was doing on the trail compared to how I’d been training at home…
