HED Jet RC6 Black Rim Brake Tubeless Wheelset

The HED Jet RC6 Black Rim Brake Tubeless Wheelset brings 60mm of deep-section carbon/alloy construction to rim brake bikes — the depth that makes a measurable difference on flat roads and rolling terrain without becoming unmanageable in a crosswind. It is built for riders who want genuine aero performance and are not looking to abandon their rim brake setup to get it. At $1,800, the RC6 Black sits at the top of HED's rim brake offering, and it earns that position through three decades of refinement in the Jet series, not a recent redesign.

The rim uses HED's carbon/alloy hybrid construction: an alloy base with a carbon aero fairing bonded over it. That combination delivers a 60mm deep-section profile while retaining an alloy brake track — which matters more than it might initially seem. HED applies their Turbine Braking Technology to that surface: a textured, all-black alloy track engineered to improve brake response in both wet and dry conditions. In the dry, the textured finish reduces the lever effort needed to achieve the same stopping power. In wet conditions, it maintains grip where a smooth surface would fade. Beyond weather performance, the alloy brake track eliminates two concerns associated with full carbon rims: heat buildup on long descents and the need for specific carbon-compatible brake pads. Standard brake pads work fine on the RC6 Black, which makes it a practical choice for training as much as for race day.

Depth, Width, and Tubeless Setup

At 60mm deep, the RC6 sits between HED's 38mm RC4 and 90mm RC9 in the Jet Black rim brake lineup. It is deep enough to deliver a clear aerodynamic advantage over shallower wheels on open, flat roads and in triathlon — and composed enough in crosswinds that it does not demand a pilot's attention every time conditions shift. The 21mm internal rim width, which HED standardized across the Jet series in 2014, accommodates both clincher and tubeless tire setups and pairs well with modern 25–32mm tires without the turbulence at the tire-to-rim transition that narrower rims produce. Set up tubeless and you can run lower pressures than a clincher allows, which adds compliance over rough or variable pavement — a meaningful improvement over long road rides and triathlon courses alike. Tubeless tape is applied at the factory; valve extenders and quick-release skewers are included in the box. Maximum recommended tire pressure is 80 psi.

Hubs, Spokes, and the HED Build Standard

HED has been hand-building wheels in Roseville, Minnesota since 1984. Every RC6 Black wheelset goes through that same facility. The front wheel uses a HED Sonic 515 hub with 6900 2rs radial bearings, laced radially with 18 bladed straight-pull spokes. The rear runs a HED Sonic 545 hub with 6902 2rs radial bearings and 24 bladed J-bend spokes in a 2x cross pattern. Total wheelset weight is 1,795g. Freehub options cover Shimano HG for Shimano and SRAM 11-speed systems and SRAM XDR for current SRAM AXS drivetrains. HED backs every wheelset with a 5-year warranty — which, given that riders have reported decades of reliable use out of earlier Jet generations, reflects confidence in the construction rather than just a standard policy line.

For the rider on a rim brake road or triathlon bike, the RC6 Black addresses an increasingly specific need. As the broader wheel market has shifted toward disc brake compatibility, well-developed rim brake options at this depth have become harder to find. HED has kept the Jet RC Black series current and competitive. Whether the plan is a triathlon, a road race where a 60mm rim is the right call for the course, or a straightforward upgrade from the stock aluminum wheels that shipped with the bike, the RC6 Black delivers aerodynamic depth, braking confidence, and hand-built construction quality backed by a company that has been producing this category of wheel longer than most of its competitors have existed.
