These are very similar to the Shimano RS80 C50s, smooth Shimano Ultegra hubs laced with nice and tight Sapim spokes; they perform well in gusts of wind. The weight of the Pro RC50′s are noticeable on the climbs, gyroscopic affect is increased when at speed when makes the RC50 feel really quite stable on the descents.

Rather than uni-directional carbon they are made with coarse weave 12k, a very steady wheel.  RRP £899.98.
