Hi everyone.

I've decided to buy my first powermeter. I had a lot of fun during this winter, training on my kickr Core and being able to see my power outlet and to train around it.

I narrowed it down to the two mentioned in the topic.
https://www.power2max.com/en/product/ng ... crank-set/
Or the Assioma Duo pedals.

I know there's pro's and con's with both, but if anyone has some insightful knowledge about either of them I would be happy to hear about it. Having a rough time making a decision, since it's my first powermeter.

I decided on one of the two, since my budget is around 700 Euro.

My current bike is a Canyon Aeroad CF SLX.

If there's other options in my price range id like to hear about them.

Thanks

/Kris

Are you married to your Shimano or time pedals? If not, the Assioma are extremely good.

SPD-SL pedals are easier to clip into IMO. Some people will say SPD-SL pedals are a wider, more stable platform. Not a good enough reason for me to stick with them when the Assiomas and Vectors are both very good PM options. I also find my pedal PMs to be the most consistent. Spider based PMs can misread if chainring bolts aren't all properly torqued. I find the temperature compensation on my Quarq to cause more dramatic swings in power readings than Vector 3s or Assiomas. Not sure if the P2M is any better about that.

Thanks for your reply.

Leaning abit towards against the Assioma's I think.

I also like the fact that I can easily mount them on a new bike, if/when i replace my current.

100% agree with Tobin, the only flaw I find in my assioma is a direct consequence of their weight. SPD-SL are back heavy that makes them always point to the top, assioma are more balanced and tend to spin more when missclipped.

With the advantage of being able to have a power meter when I rent my bike while traveling I went for the assioma and don't regret it

I’ve had about 5 different P2M power meters over the years and they’ve all be rock solid, no drop outs, no crazy spikes, they are a solid choice. I’ve also sold all of them and use DUOs now as I like that I’m able to swap them on to any bike I want and they give a true L/R power. They’ve also been as reliable as the P2M units, it’s just easier for me to swap pedals then it is to fuss with swapping cranks....and honestly I don’t want to tempt messing with BBs and introducing a potential for creaking with frequent install/removal of cranks.

Go with the P2M. It's the trouble free option.

+1 for power2max. Been using them since their first models, totally bomb proof.

Have zero experience with the duos, but believe they are very good.

Removing the actual power meter from the equation, in 39years of training and racing, I have been through many sets of pedals due to crashing and bearings/spindles failing. I have never had to retire a set of cranks for any reason other than esthetics.

You can buy all spare parts of the pedals and they are self serviceable. This point was actually the one that made me take them over the vector3

I have both - duos for my road bike and PM eco for my CX bike. Both work perfectly, and I would buy the duos for the road bike and PM for the CX bike any time again if I needed too.

I've had a P2M and Vector 1/2. I had Vector 3 as well but that went back for a refund after one week.

In my experience the P2M is absolutely bullet proof, whereas my Vector's have had a combination of quirks. Based on that experience I'd go P2M as it's the most consistent PM I've had. Pedals definitely have their place for a multi bike set up though.

If your cranks are also 8000, you could send them in to Pioneer to have a dual-sided power meter installed for about your price range.

Thanks for all the inputs and advice, it's very appreciated.

But after some consideration, I think im gonna go for the Assiamo Pedals. They seem solid and like a good choice for me. I Defiantly wanna try out a crank based powermeter some day, but for now I'm gonna stick to the pedals.
