While we all know that the art of carbon wheel manufacturing is a science, we tend to forget that training and racing are as well. Two of the most innovative companies from these fields got together to form the PowerTap G3/Reynolds 46mm Carbon Clincher Wheelset. Now, whether you're training or racing, you have the right tools for the job.
In terms of weight, the G3/46mm wheelset tips the scales around a respectable 1590 grams. This is due, in part, to PowerTap's selection of the venerable Reynolds Assault carbon clinchers for the rims. Sitting near the top of its 'Performance' line, Reynolds constructed the Assault's rim from its PR3 Hybrid Carbon. As a result, the wheels tip the scales just around 20 grams heavier than the Reynolds Forty Six clinchers. However, both wheels share a nearly identical mold, measuring out to a maximum width of 20.8mm and a rim depth of 46mm. So, while aerodynamics and stability rank rather evenly, the ride characteristics differ in response to the Assault's slightly heavier carbon layup, although the Assault still features an impressive stiffness-to-weight ratio.
And while the two wheels are differentiated by a few variables, both wheels are constructed with the same proprietary carbon technology, only varying in the layup. The recipe consists of three technologies -- Hybrid Modulus Laminate (HLM), Variable Resin Chemistry (VRC), and Inert Gas Compaction (IGC). Basically, these three systems work harmoniously to construct the Assault. HLM is a method used to assign specific carbons and layups at different points of the rim. So, through this method, Reynolds placed different carbons and layups at the tire channel, brake track, side wall, internal nipple bed, and spoke face. Then, with VRC, Reynolds' exclusive resins bond the different laminates into a single structure. And lastly, IGC is used to mold and cure the rim in what Reynolds deems as the most ideal of environments. As a result of this construction process, the Assault is strengthened at strategic points and benefits from a light overall weight. Additionally, the wheel's layup provides higher levels of lateral and torsional rigidity under load than prior iterations.
With the Assault, Reynolds also addressed an all-too-common ailment to carbon clinchers -- poor, and sometimes dangerous, braking. The solution was found through the development of what Reynolds calls its Crynogenic Glass Transition Braking System (CTg). Essentially, this is a patented braking design that required both a redesign of the brake track laminate and pads. Accordingly, CTg uses a temperature-conductive laminate at the brake track's transition points that withstands higher levels of heat than typical carbon laminates. And when paired with Reynolds' polymer Cryo Blue brake pads, braking becomes more predictable and requires less finicky feathering on fast descents.
For the build, PowerTap used 20 radial-laced DT Swiss Competition spokes in the front and 24 spokes in a two-cross, drive-side pattern at the rear. These have been laced to a 100g PowerTap front hub and a PowerTap G3 rear hub. The new PowerTap G3 rear hub is a power meter on a diet. An 80-gram weight reduction from the popular SL+ makes the G3 rear hub the lightest power meter in the world. PowerTap improved on the rigidity of previous models for the G3 by shrinking the hub profile and widening the flanges, ending the days of heavy, stiff, paint bucket-sized rear hubs. With the distractions of weight and stealth design out of the way, PowerTap improved the functionality and accuracy of data gathering. For one, PowerTap moved the orientation of the electronics that transmit user data to the end cap of the freehub body. With the new positioning, it's now possible to remove the electronics for service without swapping out the entire wheel, equating to more time in the saddle and fewer headaches.
The new G3 is equipped with an ANT+ wireless transmitter that sends power, torque, speed, and virtual cadence data to either PowerTap's Joule GPS unit, or any other ANT+ compatible head unit. The G3 is capable of storing up to 15 hours of data in one-second gathering intervals, and up to 30 hours of data in two-second gathering intervals. The G3 design still has a 'torque tube' with eight strain gauges, yielding measurements accurate within +/- 1.5% between 40 and 130 rpm.
The PowerTap G3/Reynolds 46mm Carbon Clincher Wheelset is available in the color Black and in a clincher configuration. Please note that the rear wheel is offered with either a Shimano/SRAM or Campagnolo 11-speed compatible freehub body. Also, every wheelset includes two pairs of Reynolds Cryo Blue Brake Pads. Reynolds recommends only using its proprietary pads, and the use of any other brake pads will result in a void of your warranty. Please note that while the Forty Six's internal nipples decrease your drag footprint, truing the wheels will require a Reynolds-specific internal spoke wrench.

very good wheels
- Familiarity: I've put it through the wringer
i have to say the PowerTap G3 46 Carbon Clincher Wheelset is very fast and very stiff there is no flex while climbing out of the saddle and the brakes do not hit the rim at all some carbon rims like easton and zipps where the rim flexs when you get out of the saddle power tap did an awesome job choosing the renyolds carbon rim and building it well
