Recommend me a Power Meter - 11spd SRAM Rival

Tech Tech - What to Buy
1

My Crux is currently running 11sp mechanical Rival and I am keen to explore options for adding a power meter to the bike.

Firstly, I’m aware that power meter pedals are probably the easiest option however I would like to have the option of putting road pedals on my crux in certain circumstances and I wouldn’t want to lose the power meter in this scenario.

Currently I have an Ingrid chainring and crankset as, at the time, this was the easiest way to get myself onto 165mm cranks (11sp Rival cranksets are not easy to find any more). I’d be happy with the SRAM spindle-based power meter as a cheap and easy option but as far as I understand it these only work with DUB cranks - i.e - 12spd SRAM.

I have a Magene p505 on my road bike so one option may be to get a different power meter on the road bike and move the Magene to the crux. However I don’t know enough about crankset/spider compatibility to understand if that’s even an option.

Any thoughts/ideas?

Direct contradiction to your second paragraph, but depending on frequency of road pedal usage, I’d just get a pair favero assioma pro mx-2, and then a set of the road bodies.

more expensive, yes? But they easily work on ALL your bikes.

When I started using Trainerroad I wanted to start recording power usage off the trainer as well so trainerroad could use all that data. Pricing spindle, spider, or crankarm meters for the bikes very quickly overshadowed the cost of faveros.

Agree with this, I have it Rallys with SPD and SPD-SL bodies (bought them before Favero had the option).

Otherwise, I’d email the folks at Power Meter City and they’ll get you hooked up with your options.

Oh I didn’t realise you could swap the bodies on the Faveros. That’s a very compelling option then!

Edit - okay I looked into it. Seems great! Only concern from my side is that the road pedal bodies are shimano-based and I have Look pedals on my road bike. But that’s not an insurmountable issue.

Has it changed? My Favero assioma duo’s (road) are look/expedo pedal bodies.

The SPD Faveros are the MX-2s and the Road Pedal Bodies that fit on those are Pro RS pedal bodies which are shimano based.

As far as I know the Assioma Duo’s don’t have interchangeable pedal bodies. Also I would want the MX-2s spindles without the little power meter pod tbh.

The new Garmin pedals have swappable bodies just like the faveros, and the even have a Look compatible body (I think)

But they are laughably more expensive than the favero pedals.

FWIW, right now the Favero PRO RS-2 power meter pedals are $809 US and the PRO MX pedal bodies are $139.98 (for a left/right pair). The total for all of that is still less than the Garmin Rally RS-2 power meter pedals. That’s no slight against Garmin but rather a statement about what a gobsmacking deal the Favero pedals are. When I bought my Assioma Duos at the end of 2023, they were $759 dollars at Power Meter City.

Aside: if anyone’s got any ideas on a strategy involving either benign deception, sleight of hand, or hypnosis to convince my wife that the best thing we could possibly do right now is get a pair of PRO RS-2 pedals, I’d appreciate it.

Gotcha. Yes wasn’t current on the designed interchangeability for the MX and RS. Ironically I have the MX, having got the Duo years ago. Would have to say they have probably been the best “non-critical” thing I’ve ever bought in cycling. Work perfectly, set and forget, 100% reliability. And I hear the dramas people have with Garmin pedals (and possibly all Garmin products - just for example).

I’d pick a cheap option here - get a Geoid PM500 off AliExpress (it’s a rebranded Magene P515) for about $330 AUD. Get a decent 1x chainring from Pass Quest or Stone - probably another $60-70 AUD, and then a BB (depending on the generation of Crux - not sure if you’ve got an older one with BB30 or newer one with BSA, so either a conversion BB if BB30 or plain old Shimano BB if threaded). Substantially cheaper than the Favero/Garmin options and means you can swap the pedals over as needed.

For Rival 11 speed you can put a Power2Max NGeco in replacing the spider, keeping your existing chainrings. Its amazing, self calibrating, always just works, battery lasts me six months. Its definitely the best solution for SRAM Rival. But everyone else is right, eventually you’ll want a new bike / to have power on a rental etc, so pedals are a better holistic solution.

Big fan of the Power2Max NG Eco as well if you decide to go that route. They just work, no issues, and just change the coin cell battery when it dies. The idea of having to plug in my bike to charge things just bugs me. I much prefer removable or replaceable batteries. But that’s a me issue.

Thanks all. Some interesting options there. Favero just went on sale for a decent price which is a bit annoying as I don’t quite have the money ready to go yet! Despite the cheaper crank-based options I do like the idea of the Faveros as a longer-term investment. I won’t always have the crux, or it may not always be set up the way it is.

Also there’s no way I would personally prefer coin-cell batteries over something rechargeable :sweat_smile: I’ve got no issues plugging my bikes into the wall occasionally.
