FSA RD-600 wheels
FSA's striking-looking RD-600 wheels have three hub flanges rather than the usual two, with the addition of an extra flange in the middle of the hub. The idea is to tuck a third of the spokes into the line of the rim so that they are sheltered from the airflow, improving the aerodynamics of the wheel.

FSA RD-600 rear wheel    
Rims are 30mm deep, aluminium units for clincher tyres while the hubs have 7075 aluminium bodies. The front wheel has 18 Wheelsmith® Fedelini™ stainless spokes, while there are 24 in the rear. The Fedelini spokes have a 1.3 x 2.1 mm section in the middle, but are 2mm at the ends and have the nipples hidden in the rim for, as FSA puts it "wind, weather, weight, and beauty."

Speaking of weight, our pair weighed a total of 1805g with FSA's Scatto skewers. RD-600s are available with freehub bodies to take either Campagnolo or Shimano sprockets.
