HED Jet 4 Plus Disc Brake Tubeless Wheelset Info

The HED Jet 4 Plus Disc Brake Tubeless Wheelset sits at a depth HED calls its aerodynamic sweet spot — 46mm, deep enough for a real aero advantage but shallow enough to stay composed in real-world crosswinds. HED built the Jet 4 Plus to work across a wide range of racing and riding: triathlon, time trial, criterium, and everyday road riding all fall within what this wheelset is designed to handle well, rather than optimizing narrowly for one discipline.

The rim uses HED's alloy spine and carbon fiber fairing construction, a hybrid design that traces back to how HED originally addressed carbon rims' historically weak braking by pairing an alloy structural core with a carbon aero shell. On this disc brake version, rim braking is out of the equation entirely, so the alloy spine's job shifts to structural durability and ride quality rather than braking surface — while the carbon fairing keeps shaping the aerodynamic profile. That combination gives the Jet 4 Plus a level of durability that a full carbon aero rim doesn't always offer, without giving up the aero shaping that makes a deep-section wheel worth choosing in the first place.

HED's Stability Control Technology is built into the rim shape specifically to manage the handling tradeoff that comes with aero depth. SCT reduces the lateral forces a rim experiences between 0 and 15 degrees of wind yaw — the range where real-world gusts and passing traffic actually hit a rider — so the wheel holds a more predictable line in crosswinds than a wheel chasing pure aero numbers without that consideration. It won't handle quite as neutrally as a shallow box-section alloy wheel, but it avoids getting pushed around the way a deep, unshaped aero profile can.

The C2 rim shape carries a 25mm external width and 21mm internal width, wider than older aero rim standards, which increases tire volume and contact patch for lower rolling resistance and more cornering grip. That wider tire profile also lets a rider run lower tire pressure without sacrificing efficiency, and it smooths the airflow transition from tire to rim for a bit less drag on top of the aero gains from the rim depth itself. The wheelset is built for disc brakes with a Centerlock rotor interface and thru-axle compatibility, which adds stiffness for hard accelerations and fast cornering compared to a quick-release setup. Rotors are not included.

The complete wheelset weighs 1,743 grams (828 grams front, 915 grams rear), laced with bladed steel spokes — 18 in the front wheel and 24 in the rear, a count that reflects the different structural demands on each end of the bike. For a rider who wants one aero wheelset that performs across triathlon, time trial, criterium, and standard road racing without needing a separate wheel for each discipline, the Jet 4 Plus offers a genuinely versatile depth and construction at a price below many single-purpose race wheels.

The RA Perspective

The Jet 4 Plus occupies a smart middle ground in HED's aero lineup. At 46mm, it's deep enough to feel the aero benefit on flat and rolling terrain, but it doesn't turn into a handful the moment a crosswind picks up — that's Stability Control Technology doing real work, not just a marketing name on the box.

The alloy spine and carbon fairing construction is worth understanding rather than skipping past. It's not a full carbon aero wheel, and it's not a basic alloy wheel either — it's HED's way of getting carbon's aero shaping with more structural durability underneath, which matters if you're using this wheelset for training miles between races rather than only race day.

The 18-front, 24-rear spoke count is a deliberate asymmetry, not an oversight — the rear wheel takes more load and torque, so it gets more spokes, while the front stays lighter where it can afford to. That's the kind of detail that shows genuine engineering rather than a one-size-fits-all spoke count applied to both wheels.

We'd point this wheelset at a triathlete, time trialist, or road racer who wants a single aero wheelset versatile enough to cover multiple disciplines, and who values a wheel that stays predictable in wind over one chasing the absolute deepest aero numbers.
