For 2013 Cycleops Powertap has added a couple models of Enve rimmed G3 hubbed wheelsets.  There are some interesting choices made by Powertap and worth noting for someone in the market for Power Race-able set of wheels.

60mm front and 70mm rear wheel.  Race ready, with the proven G3 hub.  They come in a clincher and tubular option.  1,420g tubular and 1,550 clincher.  Here are a couple things that came to mind for me when I first started looking at this product.  Sure the retail price is $3,499, but this is a super unique wheelset.  First off you can get it in a carbon clincher.  Second your getting a Powertap Factory race-able wheelset.  Third, Powertap has never really gone into the deep rim technology which is so popular among triathletes.  A 70mm rear wheel is a nice start to follow up the 60mm.  Contact us for more information.

30mm front and 40mm rear.  Super light for a Powertap Wheel, 1,355g tubular, 1,520g clincher.  Again your getting a carbon clincher which is rare in the current market.  Compare this wheelset to the Zipp 303 Firecrest Carbon Clincher.  Retail $2725, 30mm front and rear, 1475g.  So for $724 you get the addition of a G3 Hub, and a weight gains of a mere 45 grams.  If you want a race-able Powertap Wheel, look no further.
