HED Vanquish V84 Pro Disc Brake Wheelset

The HED Vanquish V84 Pro Disc Brake Wheelset is built for one purpose: moving through air as efficiently as physics allows. At 84 mm of carbon rim depth, this is not a wheelset you reach for on a climbing day or when the weather turns unpredictable. It is a deliberate choice — the kind you make when the course is flat, the conditions are favorable, and the only variable left to control is speed. Triathletes, time trialists, and road racers who have decided that every watt counts will understand immediately what the V84 Pro is for.

HED manufactures these carbon rims in the USA, which reflects decades of the brand's focused investment in aerodynamic rim geometry. The 30 mm external width and 21 mm internal width are not arbitrary figures — they are calibrated for modern 25–28c tubeless tires. Mounting a wider tire onto a wider rim reshapes the tire's profile into a more aerodynamically favorable form, reducing the abrupt shoulder transition that narrower rims create where tire meets carbon. That same 21 mm internal width also means more air volume in the tire casing itself, which opens the door to lower pressures — and lower pressures mean better compliance over road chatter, more grip through corners, and less of the high-frequency fatigue that accumulates over long efforts. The hooked bead design keeps tubeless setup straightforward and also accommodates standard clincher tires when needed.

The Pro version pairs those rims with DT Swiss 350 CenterLock hubs laced with Sapim CX-Ray bladed spokes. The DT Swiss 350 has a well-earned reputation for long-term reliability and easy serviceability — it is not a hub that demands attention, which matters when you want your equipment to stay out of the way. CX-Ray spokes are among the lightest bladed spokes available and reduce parasitic drag in the hub-to-rim zone where standard round spokes quietly cost you watts. A 24-spoke count front and rear keeps the build stiff and responsive without adding unnecessary mass. And because disc braking is entirely decoupled from the rim surface, braking performance stays consistent regardless of conditions — no degraded stopping power in the wet, no heat buildup during long descents.

Design Benefits

1. Aerodynamic Rim Geometry: The 84 mm depth is purpose-built for flat and rolling terrain where aero drag is the dominant resistance force. Combined with the 30 mm external width, the rim is designed to manage crosswind stability while presenting a deep profile that cuts through air efficiently — a balance that shallower rims cannot offer at the same speed.
2. Wide Internal Width and Tubeless Compatibility: The 21 mm internal width reshapes the tire-to-rim junction, creating a more continuous aerodynamic profile between rim and tire. It also allows lower inflation pressures in a tubeless setup, which improves road compliance and reduces rolling resistance — gains that compound over the length of a triathlon or time trial.
3. DT Swiss 350 Hubs with CX-Ray Spokes: This hub-and-spoke pairing is chosen for durability and aerodynamic refinement in equal measure. DT Swiss 350 hubs are straightforward to service and built to stay consistent across thousands of kilometers. CX-Ray bladed spokes reduce drag between hub and rim while keeping weight low — a detail that matters most at high speeds where spoke drag becomes measurable.
4. Disc Brake Decoupling: By moving braking forces entirely off the rim surface, disc construction eliminates the wear and heat-related inconsistencies that rim brakes introduce on long descents. Stopping power remains consistent regardless of wet or dry conditions, and the rim is free to be optimized purely for aerodynamics and weight — not braking surface requirements.
5. USA-Manufactured Carbon Rims: HED builds these rims domestically, applying construction standards that reflect the brand's long history in aero wheel development. That means tighter quality control over layup and finish — factors that affect both the long-term structural integrity of the rim and the consistency of the aerodynamic profile.

Final Take

The V84 Pro is a wheelset for riders who race against the clock — triathletes on flat courses, time trialists, and road riders who want the deepest aero advantage their discipline allows. The combination of HED's USA-made carbon rims, DT Swiss 350 hubs, and CX-Ray spokes gives you a build that is fast by design and reliable by construction. If you know what 84 mm is for, this wheelset will not disappoint you.
