DT Swiss PRC 1400 Spline DB 35 Carbon Wheelset

The DT Swiss PRC 1400 Spline DB 35 Carbon Wheelset is one of those rare builds that doesn't demand a trade-off. Not a wheel you pull out only when the course is flat, not a climber's-only niche tool — a full-season road racing wheelset designed to perform with equal composure on a long alpine stage, a punchy criterium circuit, or a wet spring classic. That kind of versatility doesn't happen by accident. It comes from DT Swiss making deliberate decisions at every layer of the build, from rim depth to hub engineering to tire system compatibility.

The 35mm full carbon rim sits in a depth that earns its keep across varied terrain. It's deep enough to produce real aerodynamic benefit on open roads and rolling terrain where wind resistance is the dominant force working against you — but not so deep that crosswinds become a conversation you're having with your handlebars on every exposed ridge. Shallow enough to stay manageable on long climbs where rotational weight matters, 35mm is the depth that disappears into the ride rather than announcing itself. The carbon construction keeps the overall wheelset weight well within the range expected of a performance road wheelset, and the rim profile is shaped to deliver a degree of compliance that sustains ride quality over hours, not just the first few kilometres.

Disc brake compatibility changes what carbon can do on a descent. With braking force transferred entirely to the rotor and hub, the rim never absorbs heat from prolonged stopping — the kind of heat that puts rim-brake carbon under real stress on long mountain descents. That structural separation means the PRC 1400 Spline DB behaves predictably in exactly the conditions where it needs to most. Add tubeless-ready construction and you have a wheelset that supports lower tire pressures for better grip, improved vibration absorption, and reduced pinch flat risk — particularly meaningful when the road surface deteriorates or the weather closes in.

Design Benefits

1. Disc-Optimized Carbon Rim: Because braking force never contacts the rim surface, the full carbon construction is free to be optimized entirely for stiffness, aerodynamics, and weight — not heat tolerance. On long descents, the rim retains its structural integrity without the thermal stress that rim-brake wheels must account for. That's a meaningful difference in how the wheel behaves over the course of a demanding day in the mountains.
2. Tubeless-Ready Construction: The PRC 1400 Spline DB is built to run tubeless from the start, not retrofitted for it. Lower tire pressures become viable, which translates directly to improved traction, better road feel, and reduced fatigue over longer efforts — particularly on rough surfaces where a tubed setup would demand higher pressures to avoid pinch flats.
3. Balanced 35mm Rim Depth: The 35mm profile is neither a pure aero wheel nor a pure climbing wheel — it's a wheelset designed to disappear across all terrain types. The depth generates aerodynamic return on flat and rolling roads without the crosswind sensitivity or added rotational mass that deeper sections carry. For riders who race or ride in varied conditions, that balance has real practical value.
4. DT Swiss Hub Engineering: DT Swiss hubs are among the most widely used and trusted in professional road racing, known for precision bearing engagement, long service life, and a spoke interface designed to distribute load evenly. The Spline system uses straight-pull spokes for improved lateral stiffness and reduced spoke fatigue over time — details that matter most in a race wheel you intend to use consistently across a full season.
5. XDR Driver Compatibility: The XDR freehub driver supports SRAM's XD Road cassette system, enabling the wide-range gearing configurations increasingly common in road and endurance racing. For riders running modern SRAM groupsets, the interface is a direct fit with no adapters or compromises.

Final Take

The DT Swiss PRC 1400 Spline DB 35 is built for road racers and serious enthusiasts who want a carbon wheelset capable of showing up across a full calendar of riding — not just the flat days. If you're running disc brakes, want tubeless capability, and need a wheel that handles a mountain stage as well as it handles a fast group ride, this is the build DT Swiss engineered for exactly that kind of rider. No caveats required.
