The Revolutionary “Sinusoidal” Design: A Trifecta of Benefits

A “Sinusoid” is a mathematical curve that describes a smooth and repetitive oscillation.  The WAKE 6560 has 24 such waves molded into its carbon fiber.  The profile provides benefits to mechanics, aerodynamics, and weight.

Mechanically, the dynamic cross-section variability – WAKE – puts spoke tension point at a symmetrically convex section of carbon, vs concave (typical wheel), carbon is pulled in tension vs pushed into compression. Fiber is much stronger in tension (pulling vs pushing on a rope). Results in much higher degree of stress migration from the relatively weak spoke point to the relatively strong outer hoop than a standard wheel. Ie, stiffer, more responsive.

Aerodynamically WAKE creates less drag and goes faster with less watts.  Bold claims backed by testing at the A2 wind tunnel in Moorestown, NC.   We verified quantitatively, lower drag at all yaw angles via dynamic cross-section variability. Results in reduced effects of vortex shedding by use of a constantly varying trailing edge.  While confident in the extensive CFD modeling before prototype production, the real world validation of WAKE 6560 at an independent facility was worth every dime spent.

Weight optimized through pairing advanced manufacturing with optimized mechanical design. Result: 1495g rim brake set for 62.5mm avg depth.  In a tubeless ready wheelset, not only lightest in 60mm category, but also lighter than nearly all competitors in the 35mm category.

  1. […] Princeton CarbonWorks claims reduced spoke hole stress and improved aerodynamics as advantages, the latter proven by the founders in the wind tunnel. We will not get into the engineering and physics of those claimed benefits, but you can read Princeton CarbonWorks’ explanation here. […]
