PM worthwhile on a XC bike?

Hey all, mostly a roadie but love CX and have started doing some XC. Having fun so far, working out on the road and working on skills on mtb days.

Interested in opinions about adding a power meter to the XC bike. Can’t imagine actually looking at it during an XC race but would be interesting after the fact. More interested in doing some structured work on the mtb.

Found a bunch of info about which PM options work on mtb groupsets but not a lot about how people are using the data. Thoughts?

A post was merged into an existing topic: Does a power meter for a MTB makes sense based on your location?
