These Ritchey wheels are featuring 50mm deep monocoque carbon rims and a proprietary manufacturing process. A tubular wheelset with the caliber of a ProTour-wheel, which is fast without being too hard. The Phantom Flange hubs with super light Ritchey design captures the sleek profile and efficiency of straight-pull spokes with the superior strength and durability of J-bend spokes. The premium quality sealed bearings and patented 6 pawl, 12-point micro-clutch engagement system round this wheelset up. The double-crossed spokes on the rear wheel make for some vertical compliance, but they offer sufficient resistance under acceleration, while the radial spokes prevent lateral bending.
