Hi TR users,
I just snagged a 2022 Specialized Epic full suspension and am trying to determine what kind of power meter I can/should put on it. I don’t really like the idea of a pedal based power meter so would prefer something crank based. Any thoughts? I’d also like to not replace the entire crankset since it’s brand new… Thanks.
It would help to know the exact model you got, but largely which crankset is already present on the bike.
I’d recommend 4iiii as the best if you want to keep your current crankset.
It’s the Epic Expert with the SRAM DUB BB and SRAM X1 Eagle Crankset.
Based on that, the Power2Max NGeco seems a solid option (NG too for more features). Then the Sigeyi Axo seems to have decent performance by what I’ve seen posted here.
I have a 2021 Epic full suspension and added the new 4iiii Precision 3, supposedly 800 hrs battery life 
we’ll see how many hrs it actually gets, but sounds like it is more than the usual 80-200. Also really cheap. Slick and quality appears high. See pics
nice on the bike and I got a epic evo expert a few months ago and love it. Put a chain stay, esi grips and also switch the bar with an enve m6 as the standard one did not clear the top tube.
Regarding the the PM I would do a spider or a 4iii. I have a 4iii on my Tarmac and love it but with SRAM 4iii said I would need to send in the crank so they can put it on. Not a huge deal but a little more of a pain. whatever you do good luck.
The P2M has been super solid for me. I have one on my MTB and Gravel bike and they’re super easy to install and have been pretty much flawless. Some people report the battery cover pops off but as long as you properly seat it I have never had an issue with it.
I have two of them as well, and like them. I did lose one cover on the maiden ride and was unhappy with it. My case may have been rare (hacking through some bushes in a fresh trail), but it still is an issue IMO. I added a wire tie for extra security have been happy with them since.
Yeah, I found mine loose once but it was in the first 5 min after I had installed a new battery. So I just installed it properly under the little hooks and haven’t had an issue since. It’s definitely a weak spot but not big enough to write it off. It would be more secure if it had a Quarq like cover that screws on.
Quarq, 100%
Great power meter, except SRAM insist on the need to upgrade to the XX1 crank in order to use their power meter. It’s deliberately NOT compatible with any other MTB crank they sell.
Since the OP specifically mentioned wanting to keep the current crank, the Quarq is not a great option.
Another vote for the Power2Max NGEco. I have 2 of them on different mountain bikes and they have been rock solid for me with zero issues.
