Wheelsets are booked on the Saturday and Sunday-Wheels will arrive on the Tues/Wednesday before the booked weekend.
HED JET DISC
The HED. disc is where it all began, and in 2011 the new Disc Jet is poised to pick up where the Standard disc left off.
What makes a wheel better?
Lighter, stiffer, stronger, faster ... any of these are an improvement.
With HED's new construction technology and SCT Tuning, the Jet Disc is all of these. Jet discs are a hybrid wheel, built with spokes for strength and durability. When the substrate wheel is completed, trued, and stress relieved, disc sides are bonded to the hub rim and spokes. With a two part building process, the disc sides can be made lighter and shaped more readily, without losing any strength.
The new disc incorporates a toroidal bulge near the rim and a radius on the large transition leading from the hub to the bulge. These shapes make the Jet Disc not only faster than the Standard disc, they make it faster than any other disc. ...... faster then most competitors tubular discs.
Pure speed - it will never get old.
Jet Disc. Stiff, light, fast. C2 rim for decreased rolling resistance.

HED JET 9 FRONT
Part of HED's long list of 'firsts', the Jet 9 was designed in 1995 and production started in 1996. It was groundbreaking 13 years ago. Thanks to HED's extensive re-design the Jet 9 is as revolutionary as the original. \
What makes the Jet 9 so good, and so much better than its predecessor? It is all interrelated. The new wheel is more aero, it has lower rolling resistance, it corners and handles better, and it more comfortable - all increase speed, and all are a result of our C2 rim technology. The C2 rim is 23mm wide; and that fact alone does not make it revolutionary, and by itself a 23mm rim width is not 'technology'. What we did with a 23mm rim width, and what it allows for aerodynamics, rolling resistance, and bike handling are what make the C2, and the new Jet wheels revolutionary.
First, the rim itself. With exacting CAD design and the resulting extrusion dies that can be machined from the instructions in a CAD file, we can make a 23mm wide rim that weighs no more than the 19mm rims that were standard for the industry (including HED) for years. The additional width actually makes the C2 rim stiffer laterally than a 19mm version.
With a better rim to start from, the Jet wheels are faster. Jets are made for 23mm tires. Larger tires have lower rolling resistance than smaller versions. They put more rubber on the road for better cornering traction. They require less psi to support the same load as a 19mm tire. 23mm tires are superior - now that we have the proper rim for them. With the C2 rim, tire width matches rim width, so the wheel is more aero. The tire sidewalls are part of the aero shape of the entire wheel, they don't bulge over the brake track like they do on a 19mm rim. The same straightened sidewalls support the tire better in hard cornering and out of the saddle efforts, so the complete tire is more rigid and less squirmy. Stiffer is more efficient than squirmy, and more efficient is faster.
As a front wheel they are a good choice for athletes that ride at 25mph or faster in light and medium wind conditions. For those athletes that are riding 25mph or less the front wheel should be reserved for days when the winds are light.

The 2008 introduction of the C2 platform was a dramatic improvement over our previous designs: aero drag was reduced substantially, and the use of wider tires dramatically improved cornering. Since the introduction of the C2 platform, HED. has spent two full years developing SCT, our
proprietary rim profile tuning process. Each rim depth is shaped for lowest aero drag and fine-tuned to maximize stability in crosswinds.
