HED Scorpio Flamme Rouge Tubular Wheelset $0.00
Hed's Scorpio Flamme Rouge Tubular Wheelset is lethal poison to your competition. When the "sting in the tail" of a vicious climb appears, those riding these Scorpios grin like a Cheshire cat, and romp away as their opponents feel not only the bite of gravity but the agony of watching the rider they've marked dance away as if he has light socks.
Hed, as a company that made its name on fast wheels, is new to the climbing wheel category. But, being Hed, they made a wheelset that's still fast, yet optimized for strong riders spending entire days going up and down long, steep hills.
The Scorpios are climbing wheels, but they aren't flimsy. Stiffness is essential for good power transmission and predictable, safe cornering. And since anything that goes up, must come down, these wheels are also seriously aero, and that's where Hed sees their mission. They want their wheels to save you energy on the lead in to the climb as well as on the climb itself. As with all their new wheels, they've abandoned the old 19mm rim standard for a wide shape. In this case the rim starts with the C2 tire well (23mm in width) and bulges out to 25mm to complement the 33mm rim depth. C2 stands for for low Cda (aerodynamics) and Crr (rolling resistance) and means the tire and rim “…featherlight yet aerodynamic, these Scorpios are the right wheels for mountainous terrain…” work as a unified shape to slice through the air. Because of this, the rim is optimized for tires 22-23mm in width. Wind tunnel data shows it to keep an excellent drag profile of 120g of drag from a straight headwind to 12.5° of yaw. Because Hed is always testing and refining, this wheel is as fast as the much deeper 2008 Hed Stinger 6.
The Scorpios use Hed's Sonic hubs. They run ABEC5 bearings on oversize axles, 12mm up front and 15mm in the back. These oversized axles flex less, resulting in smoother running bearings and less drag. They spaced the flanges as widely as possible to create a stronger bracing angle for the spokes, resulting in better lateral stiffness. The front hub is built with aluminum ends bonded to a carbon-fiber center. The rear hub has a solid aluminum body with a grease port covered by a carbon-fiber cap. The pawl mechanism for the freehub body uses a titanium ratchet ring for weight savings.
Instead of having radial spokes on the left side, like older Hed wheels, both sides have two-cross lacing and standard flanged hubs. Hed made this change for a simple reason. Increased stiffness equals increased efficiency. With ever-stiffer frames, pedaling forces were being transmitted to the wheels, and this reduced the mechanical efficiency. To counter these forces, they stiffened up the rear wheel so that no power would be lost to wheel flexing, thus putting more power into driving the bike forward.
The Hed Scorpio Flamme Rouge Tubular Wheelset comes with 18 front spokes and 24 rear. They utilize Silver Sapim CX-Ray straight-pull spokes for the radial laced front wheel and CX-Ray J-bend spokes in a two-cross pattern in the rear. Sapim's spokes are not only strong; they're the fastest on the market. The spokes are threaded to aluminum nipples containing thread-locking compound with spoke wrench flats on the outside and hex-heads inside. The rear wheel is available to fit either Campagnolo or Shimano/SRAM compatible cassettes. The freehub bodies switch easily with two 5mm hex keys. The Scorpio Wheels come with valve extenders and Hed titanium skewers. Any carbon-specific brake pad should work well with Hed's braking track. Hed does not recommend this wheel for people weighing over 190lbs.
