Juego de ruedas sin cámara HED Jet 6/9 Plus con freno de disco

The HED Jet RC6/9 Pro Disc Brake Tubeless Wheelset is built on a straightforward observation: the front and rear wheels are doing fundamentally different work, so it makes sense to spec them differently. The 60mm front sits where crosswind sensitivity matters most — deep enough to slice through clean air efficiently, shallow enough that a gust doesn't pull at your bars mid-corner. The 90mm rear lives in the slipstream, sheltered from the worst of lateral wind pressure, where the aerodynamic return on a deeper rim is highest and the handling trade-offs are lowest. It's a pairing that experienced racers have landed on intuitively for years. HED has built it into a single disc-brake, tubeless-ready package.

HED has been developing wheels in Minnesota since 1985, and their engineering tends to follow physics rather than fashion. The foundation of the Jet RC6/9 Pro is HED's C2 rim shape, built around what the company calls "Bag of Air" aerodynamics — the idea that the tire and rim should function as one integrated airfoil, not two separate components working at cross-purposes. The wide-body rim bed, wider than most competitors at comparable depths, opens up the tire's sidewall profile so that 25mm to 28mm tires sit flush with the rim's outer edges rather than pinching inward at the bead. That integration is where the aerodynamic story actually lives: a smoother transition from tire to rim means less turbulence, and a consistent profile across a range of real-world tire widths means the system performs as designed whether you're rolling 25c on race day or 28c on a longer training block.

The disc-specific construction isn't incidental. Disc braking changes where forces enter the wheel — braking loads travel through the hub and spokes rather than the rim braking surface, which demands a different approach to hub flange geometry, spoke lacing, and rim construction. The Jet RC6/9 Pro is engineered from the ground up for these load paths, not adapted from a rim-brake design. Pair that with tubeless compatibility built into the rim bed from the start — with bead seats designed for airtight sealing under sustained pressure — and you have a wheelset that reflects how road cycling is actually ridden in 2024: disc brakes, wide tires, tubeless setup as standard rather than exception.

Design Benefits

1. Mixed-Depth Pairing Balances Aerodynamics and Control: Running a 60mm front and 90mm rear isn't a compromise — it's a deliberate calibration. The front wheel handles steering input and is most exposed to crosswinds, so the shallower 60mm depth keeps handling predictable in variable conditions. The rear, protected in the draft, gets the full aerodynamic benefit of a 90mm rim without the crosswind sensitivity penalty that comes with deep front wheels.
2. C2 Wide-Body Rim Shape Improves Aerodynamics Across Tire Sizes: The wide-body rim bed creates a smooth aerodynamic transition between rim and tire, which is where most wheelsets lose efficiency. By matching the rim's outer width to the inflated width of 25mm to 28mm tires, the C2 profile maintains a consistent airfoil shape rather than creating the "lightbulb" effect of a narrow rim under a wide tire. The result is a system that performs as intended with the tire sizes most riders are actually using.
3. Disc-Specific Engineering Throughout the Build: The hub flanges, spoke geometry, and rim construction are all designed around disc braking's load distribution. When you brake hard into a corner, forces enter the wheel through the hub rather than the rim — a distinction that matters for long-term durability and immediate stiffness under load. This isn't a rim-brake wheelset with a disc rotor bolted on; the architecture reflects how disc bikes actually transfer energy.
4. Tubeless-Ready Rim Bed Built for Reliability: The bead seats are machined and shaped to hold an airtight seal under race conditions, not just in controlled setup environments. Running tubeless on long days — where the ability to self-seal a small puncture without stopping is a genuine performance advantage — requires a rim that holds pressure consistently. The Jet RC6/9 Pro is designed for that from the start, not retrofit to meet the spec.

Final Take

The HED Jet RC6/9 Pro is built for the rider who wants a disc-brake tubeless wheelset engineered around how modern road racing and fast training actually work — wide tires, variable conditions, real-world aerodynamics rather than wind-tunnel theater. It suits the competitive road cyclist who races crits and gran fondos on the same wheels they train on, and who wants a front-rear pairing that makes a considered engineering argument rather than simply matching depths for symmetry. HED has been doing this long enough to get it right.
