I have a Power2Max NG Eco power meter with a Rotor ALDHU crankset and 24mm spindle. I want to change the cranks from 170mm to 165 and keep everything else and I'm curious to know if the Zrace cranksets that are sold on AliExpress are interchangeable because it seems that they are almost a carbon copy of the Rotor ones. Any idea? Has anyone tried it before?
Thanks for your help
