Good deal on Rotor 2InPower Kapic crank: worth it or not?

I noticed a very good deal on a Rotor Kapic (= aluminium) two-sided power meter crank, it is on sale for less than 400 €. I don’t have a power meter on my commuter (an MTB hardtail), and I dislike the 175 mm XTR cranks on it.Two points are holding me back:

  • Rotor 2InPower meters have not tested super well according to @dcrainmaker and GPLama.
  • This is a MTB crank and I plan to get a gravel frame next. Can I use “road” chain rings when I put them on a gravel frame? This is important as there are zero mountains (think Netherlands) and I put a 38-tooth chainring on my hardtail.

What do you say? Worth it?

Primarily, I’d use the power meter to keep myself in check and to log power numbers to get better prediction of fatigue in TR. Occasionally, I might also train on it.

I’ve used my 2inPower for years and find it fantastic

I’ve tested it vs my Neo and Assioma’s and it’s pretty consistently +/- 1-2%. Plenty fine for my race bike

Only caveat w rotor is that their rings have different adapters to the crank than other brands. So they aren’t interchangeable And their eComm site is not very good.

I really like the configurability w rotor.

I placed my order, thanks. I could have saved another 100 € or so if I went for a one-sided power meter.

I haves had a Rotor chain ring for my XTR M9000 crank, and the build quality was exceptional. Peak torque and other reviewers also rate them highly. The new rebranded Wheeltop groupset not so much, but the cranks and chainrings are great.
