These are 24h HED Belgium rims laced to DT Swiss 240S front and PowerTap G3 rear hubs. With a 24h PowerTap you would be correct if you guessed the rider is a superlightweight.
As usual the rider supplied the power meter. For the record I have explored offering PowerTap products but access is locked up in a fearful distribution model. The result is people acquire their PowerTaps from online discounters and that works fine too. Inquire for advice.
