a bit out of topic but what powermeter are you using with the zele cranks?
I have the same cranks and deciding whether to get a spider based or pedal based PM.
I am using a SRAM Quarq. If you intend on purchasing an aerosensor at some point there's possibly some merit to opting for a dual-sided pedal system. Quarqs are nearly as good, ~1/5th the price, and allow for experimenting with aero pedal options.
