Riding for hours in Z4 -- are my HR zones off?

Depends what crankset you have maybe. I’ve got the same sram gpx cranks on both my bikes, and the same pedals, so swaping the left cranks arm is actually quicker than changing pedals.

That’s a fair point. I have a Praxis Zayante Carbon 1X on my gravel bike, and a SRAM NX1 on my MTB. I don’t think I’ll be upgrading that MTB to a carbon crankset in the future, though.
