Do you still have just the one bike? A disc powertap will mean you'll only be able to use that wheel on frames that can accommodate them. Which is fine if you don't plan on n+1, but Powertap pedals would be a good choice if you want to do a turbo session on your TT bike (for example) one day and then go on a long Sunday ride on your disc road bike the next.
Yep, likely to stay that way unless, I manage to get in to TCR and there is all sorts of gravel. Can’t see me ever being in to TT’ing. Hill climbs maybe.
But maybe pedals is a better option...
The battery life seems quite short though.
