The Princeton CarbonWorks Wake 6560 was conceived in 2012, with initial riding models completed in 2015. Since then, there have been 4 iterations of our flagship wheel, each offering improvements in aerodynamic performance and efficiency, weight, stiffness, responsiveness, and quality. A unique and balanced combination of attributes has made the Wake 6560 the go-to wheel for those looking for peak performance: aerodynamically faster than deeper wheels, lighter and better-handling than shallower wheels, all while stiff, responsive, and lively under power. And now, in its fifth generation, the legend evolves. The Wake 6560 Evolution ushers in a revolutionary new shape, the second wheelset in our Evolution series behind the Alta 3532. Extensive testing and development has resulted in a wheelset that is even more efficient than its predecessor, the Wake 6560 Strada. More impressively, the new Wake 6560 Evolution has been the largest step change in performance from one version to the next, amongst all iterations of the Wake series. Instantly recognizable versus previous versions, the shape of the Wake 6560 has substantially changed. Our new Evolution profile matches alternating deep and shallow rim sections with alternating spoke sides. Mechanically, this allows the steeper, high tension spokes (drive side rear spokes and disc side front spokes) to connect to a deeper rim section, thereby flattening those spoke angles. The change in bracing angle helps balance spoke tensions, creating a stiffer, more uniform wheel. This patented technology, Radially Staggered Lacing, is exclusive to Princeton CarbonWorks road wheels. Wake 6560 Evolution is also incrementally wider and lighter than its predecessor. The increased width (21mm internal, 28.2mm max external) is optimized for the 25-28mm tires that professional cyclists currently race on. The result is a wheel with even better aerodynamic efficiency at all yaw angles and better composure in tricky crosswinds. Rim weight has been reduced by 10g per rim, helped by the overall shorter cord length of the inner edge. The rim brake and hooks live on. Ride how you want, with what you want. Rim brake rims will always be available and Wake 6560 Evolution will continue to have a hooked, hole-less, tubeless ready tire bed, which can accommodate clincher/tubed tires or tubeless tires with no tape needed and no tire pressure restrictions. Rim brake options will be added to web-ordering shortly, for the time being please email info@princetoncarbon.com to order a custom or rim brake set
