As consumers, we love it when naming conventions are obvious. So the Hed Ardennes SL Clincher Wheelset makes lots of sense. But as generally creative types, we can feel a bit constrained when the names explain themselves so clearly.FR vs. SL. This wheelset is light, but doesn't pull out all the gram-shaving stops like the FR, which saves you money for tires and tubes. The Scandium hoops of the FR have remained the same and are paired up with the carbon-shafted, aluminum end-capped FR Sonic front hub, and an all-aluminum rear hub. The titanium ratchet ring is gone as are the Ti-shafted skewers. To hold the line when wheels are clamped into increasingly stiffer frames, Hed has gone from a two-cross/radial lacing pattern to a two-cross pattern on both sides laced to a traditional flanged hub. The extra crossed spokes will maximize power transfer while minimizing flex.Otherwise, this is the same C2 concept wheelset that has been turning more and more heads as the world warms to wide rims. As you've certainly read in our other write-ups of Hed wheels, C2 is for the two Cs that the 23mm wide rim improves. Cda, aerodynamics, and Crr, rolling resistance. That is, the rim reduces both aerodynamic drag and road friction. Making a rim 23mm wide and 25mm deep when most rims are around 19mm wide and 19-23mm deep is a big difference. The reason for the greater width is because of 23mm tires, the minimum tire width you almost always should be using on the road (there are 22mm clinchers; these will work, too). A 23mm rim paired with a 23mm tire changes the tire's footprint. It grips better in a straight line, and it grips better in turns because the tire deforms differently and more evenly. A 23mm tire on a 23mm rim also has lower rolling resistance. Hed sent the wheels to Continental Tires for testing. Conti's engineers shrugged their shoulders, figured there was no difference, but put them in the jig and ran the tests anyways. It turned out the 23mm width has 18% less rolling resistance. And because of the smoother tire shape, the transition air makes from the edge of the tread to the sidewall to the rim wall to the end of the rim is smoother, resulting in a more laminar air flow and less aerodynamic drag. Hed isn't calling it quits after producing such a rim, though. They've laced the rim with Sapim's popular and aerodynamic CX-Ray spokes, and hold them in place with self-securing aluminum nipples. The spokes are straight-pull and radially laced in front and J-bend and two-cross in back. The spokes are anodized Black.The Sonic hubs are also of Hed's design. They run ABEC5 bearings on oversized axles, 12mm in front and 15mm in the rear. Hed spaced the flanges as widely as possible to create a stronger bracing angle, resulting in better lateral stiffness.The Hed Ardennes SL Clincher Wheelset comes with either a Campagnolo-spline cassette body or a Shimano/SRAM-spline body. The rims are anodized Black and have machined brake tracks. The wheels come with Hed's st

I am trying to decide what wheels to get for my 2011 SL3 Tarmac and I cant make up my mind. If you own the Mavics SL or the HED Ardennes can I get your 2 cents? I need to make a decision in 1 week.
I am also open to other suggestions please feel free to give me your input on oth ... Read More »
