Congratulations on your powertap :-)
Of all the widgets and gadgets out there, I have found the powertap (PT) to be, by far, the most useful by a wide, wide margin.
About your buy: I have a powertap pro and kind of have the opposite scenario - I've (in typical fashion) misplaced the cadence sensor so I use it without the actual/'real cadence. Mind you, it still has virtual cadence whereby the hub can guess very closely at that, as to what your cadence is. Caveat is, that this works best for the more common cadences I think, say between 50 and 100. Over 100 and all bets are off.
From what I remember, and I could be way off, this is basically the same hub you have - again, minus the cadence sensor.
The tri-sports people are pretty helpful by the way so you can call to confirm if you like - i got my PT from them and they did a great job.
Power training has been a huge boon for me since I started riding this year.
Best of luck![]()
