The PowerTap G3 is so light; it's hard to believe there's really a power meter inside it. The hub weighs a mere 325g, which is lighter than many rear hubs on the market today. The hub's strain gauges are accurate to within 1.5% and aren't temperature-sensitive. The hub's electronics are actually separate from the hub, so if you ever have an issue, you can pull them out, and either replace them or send them back while still riding the wheel.
The ENVE Clincher rims are unlike any others you'll find on the market. They employ SES, Smart ENVE System, a thinking that looks at the wheels as a package inseparable from the rest of your bike. Because the front and rear wheels experience forces differently, the rims are different.
The front wheel has a shallower profile, 35mm deep, and wider, 26mm, than the rear. This shape is to make handling in crosswinds easier, and steering light and predictable. The rear wheel is deeper, 45mm, and narrower, 24mm, both for slightly improved aerodynamics—as you don't steer with the rear. The wheels give a linear response, which makes them highly predictable. This might not seem like a big deal, unless you've been riding along and suddenly had a side wind gust push you off your line. Knowing that they handle predictably will make it easier to go into the red. They're still fast. Faster than some 60mm deep wheels out there. Smart shaping is the trick.
But ENVE is about more than shape. They're a carbon-fiber company. These hoops are strong. The spoke holes haven't been cut, they've been molded, so they're stronger. The spoke nipples are inside the rim, which contributes to both the overall strength of the wheel and better aerodynamics. The brake track is one that, when paired with the ENVE pads, results in rim temperatures that run lower than many alloy rims, which means that there won't be overheating, and the braking will be safe and predictable in both the dry and wet. As ENVE is based in the mountains of Utah, they take rim heating very seriously. They depend on their wheels braking well on their daily rides.
In addition to the brake pads, which are mandatory for the warranty, the wheels are delivered with titanium-shafted ENVE skewers, rim strips, and two sets of valve extenders.
We've been discussing rims, but these are wheelsets. As such, there are two hub options. One is a DT Swiss 240 front hub with a PowerTap G3 rear, the other is Chris King R45 Ceramic front with a G3C rear. The "C" stands for ceramic bearings, which roll smoother and save you another 10g. Both are built 20/24 with DT Swiss Aerolite spokes, radial lacing in front, two cross in back. Both are available with Shimano/SRAM 10/11 and Campagnolo 9/10/11 cassette bodies. The DT Swiss weigh 1579g for the set, while the Chris King weigh 1522g.
ENVE stands firmly behind their products. Not only do they have a five-year warranty on their products, but they also have a lifetime crash replacement policy where they'll replace any ENVE product for 50% of MSRP, provided the customer has the paperwork to prove original ownership.
ENVE and PowerTap have teamed up to bring PowerTap's latest power meter technology with ENVE's lightest aero clincher rims.
