This is the problem.. you're allowed stuff mounted on the seatpost though. I think powerpod could work that way. I don't know the options for track bike crank power. I suppose the other option is Garmin vector but I like SPD-SL.
A Powerpod has to be mounted on the front of the bike - it's effectively a wind sensor that back calculates power rather than measuring it directly with a strain gauge. I'd find something else TBH
