I am in the market for a new power meter for my cross bike. After much deliberation, I’m going to go with a Power2Max spider based. My road bike currently has Assioma pedals and the pedals are what I’ve been using with TR using power match. Here’s my question and potential workaround. I’ve done all …

Yeah, I think that’s a solid solution if using 2 different bikes on the trainer is worth the hassle

What I do is this. Perform an FTP test with the alternate bike/meter, but don’t accept the result so that it doesn’t enter the FTP history if you want to keep your FTP history consistent (but make a mental note of the FTP from the test). Then when you use your alternate bike, adjust the workout di…

Two drawbacks to this approach: Your TSS, IF, NP and other FTP based metrics will be off using this approach when using the P2 max. Your friends might tease you for consistently not matching the prescribed workout :stuck_out_tongue_winking_eye: Is there a particular reason not to just leave one …

[image] huges84: Your TSS, IF, NP and other FTP based metrics will be off Did not think of this. I forgot TSS is based off FTP (indirectly) and this would mess with things. [image] huges84: Is there a particular reason not to just leave one bike on the trainer Not really. My position …

I would say it’s worth doing the comparison and then evaluating from there. The difference maybe very small and you may even be able to get the PMs to read identical by using an adjustment factor. You could alter the crank length value for the Assiomas until the power matches and then just make sure…

One thing I forgot to add, after the workout you can adjust the FTP for that session to the FTP of the alternate bike. Your metrics should all be corrected for the new FTP.

[image] CaptainThunderpants: So if I throw my cross bike and new P2M on the trainer, the power readings will be off. My thought is that I can put both power meters on my cross bike and do a few rides, then analyze the power readings myself to find a differential, maybe even at a few different po…

So… I got the new power meter (Power2Max) and mounted it on my bike along with the Assioma pedals. I then mounted it on my trainer and did a workout recording on 3 different devices. Using DC Rainmaker’s Analysis tool, I found something interesting things. I had always assumed my Direto was off hig…
