HED Jet RC9 Black Rim Brake Tubeless Wheelset Info

The HED Jet RC9 Black Rim Brake Tubeless Wheelset is the deepest option in HED's Jet RC Black series — a 90mm aero road wheelset for riders who want maximum speed on flat terrain and haven't made the move to disc. The Jet RC Black line has real racing history behind it; HED points to the first modern UCI World Championships TT win on clinchers as having come on the Jet 9. Over more than three decades of production, that design has been refined into a wheel that remains competitive on modern race courses: alloy rim core with carbon aero fairing, Turbine Braking Technology for rim-specific stopping performance, and full tubeless compatibility. At 90mm, the RC9 is built for flat courses, time trials, and criteriums where aerodynamic drag is the dominant force and crosswind management matters more than climbing weight.

The construction sets this wheel apart from full-carbon alternatives. The Jet RC9 is not a full carbon rim — it uses an alloy rim core with a carbon aero fairing bonded to it, a deliberate engineering choice that HED has refined over decades. The alloy core provides a consistent, durable foundation for the brake track and tire bed; the carbon fairing creates the 90mm aerodynamic profile. The 21mm internal width, a dimension HED standardized in 2014, supports modern tire sizes at real-world pressures without the squirm that narrower rims introduce. The rim bed is tubeless-ready with a maximum tire pressure of 80 psi. HED's Stability Control Technology shapes the 90mm rim profile to manage sidewind forces across yaw angles of 0 to 15 degrees — the range a rider actually encounters on course — so the depth doesn't become a handling liability in crosswinds.

Turbine Braking Technology is HED's patented approach to the braking surface, and it's what makes this wheel viable in the rain. The brake track is finished with a textured, all-black surface — not smooth, not polished. In dry conditions, the texture increases contact between pad and rim, delivering more stopping force per unit of lever pressure. In wet conditions, the texture channels water away from the braking zone rather than allowing it to pool between pad and rim — the condition that causes the delayed, inconsistent braking that made early carbon rim surfaces unpredictable in races. HED's position is that the Turbine Braking surface outperforms both alloy and standard carbon rims in wet conditions. Combined with the alloy structural core, the result is a 90mm aero wheel that doesn't require dry-weather conditions to stop predictably.

The RC9 runs HED's Sonic 515 front hub and Sonic 545 rear hub on radial cartridge bearings — 6900 2rs at the front, 6902 2rs at the rear, both serviceable. Front lacing is fully radial with straight-pull bladed spokes; the rear uses 2x crossed J-bend bladed spokes for improved drive-side tension. Spoke count is 18 front and 24 rear. Wheel weights are 845g front and 1,070g rear, putting the set at approximately 1,915g. The Sonic hubs are built to HED's standard serviceable design, consistent with their full wheel lineup.

The Jet RC9 Black ships in a single black colorway with freehub options for Shimano HG, SRAM XDR, and Campagnolo. It is handmade at HED's facility in Roseville, Minnesota — the same shop that has been producing Jet wheels since 1984. The RC4 (38mm) and RC6 (60mm) depths in the Jet RC Black series share the same alloy-core construction and Turbine Braking Technology for riders who prioritize crosswind handling or mixed terrain over flat-course maximum depth. At $1,900, the RC9 is a purpose-built aero rim brake wheelset with a race record behind it, made by a manufacturer that still produces them domestically and backs them with a five-year warranty.

The RA Perspective

The Jet RC9 comes up regularly when we're talking to time trialists and flat-course racers still on rim brake bikes. It's the right wheel for that conversation. Ninety millimeters is deep — you feel it on flat roads and into headwinds, and HED's crosswind profile means it doesn't punish you on rolling terrain the way some deep sections do.

The construction is worth explaining because it surprises people. This isn't a full carbon rim — it's an alloy core with a carbon fairing. That means the brake track is alloy, with the Turbine Braking texture machined right into it. The result is genuinely reliable wet-weather braking. We've worked with plenty of carbon rim brake wheels that perform well in the dry and fall apart at a rainy race. These don't behave that way. The texture makes a real difference.

Weight is the honest tradeoff. At roughly 1,915g the pair, these are heavier than a comparable full-carbon rim brake wheelset. The alloy core adds grams you wouldn't carry on a climbing wheel, and 90mm depth doesn't help on anything that goes uphill. This is a wheel for flat courses, TTs, and fast rides where elevation change is minimal.

We also appreciate that HED still builds these in Roseville. You can send a wheel back for service and get it rebuilt by the people who built it, with the same parts. That matters on a wheelset you're actually racing on, not just riding recreationally. For the rim brake rider who wants depth without compromise on braking performance, the RC9 Black is the wheel we reach for first.
