I assume AeroCoach is still doing Powertap hubs in the disc wheels. One thing I always wondered about those was what the savings of using the PT disc with a good aero crank like the Metron would be over running the regular disc with something like a Shimano crank. Is that something you looked at and are the PT options still available ?
It’s a good question - actually that’s exactly what I’ve done on my pursuit bike (Miche Primato Air aero cranks plus an AEOX track disc with a track Powertap hub) as it’s more aero than power based cranks plus an AEOX disc. A lot is going to depend what cranks you’re using - those Miche have very low Q Factor which is the majority of the improvement really. We’ve done Miche vs Tiagra on a TT bike before but that was including a front mech and inner chainring removal as well (it was 9w faster in total).
We can do PT hubs as a special build, you just need to email the site. Too many options and potential customisations for a drop down list of spoke count, type, hub model etc!
