DT Swiss ARC 1400 DiCut Disc 62 Wheel - Rear

The DT Swiss ARC 1400 DiCut Disc 62 Wheel - Rear sits at a depth that most experienced road riders would call the sweet spot for all-conditions aero performance. Sixty-two millimeters is deep enough to generate real aerodynamic advantage on flat roads and fast descents, but measured enough that crosswind management stays in your hands rather than becoming its own event. You get the speed benefits of a deep-section carbon wheel without the aerodynamic anxiety that comes with pushing into 70mm or beyond. For riders who race diverse courses, log serious training miles, and want a wheel that performs when conditions aren't ideal, that balance is worth understanding before anything else.

DiCut is DT Swiss's proprietary carbon manufacturing process — and it represents a meaningful step beyond standard autoclave production. Once the rim is molded, excess resin is mechanically removed from the carbon laminate. That process reduces weight while improving structural consistency throughout the rim profile, so the carbon that remains is doing active structural work rather than adding mass without function. DT Swiss designs and produces this wheel entirely in-house, from the carbon fiber rim layup through to the hub internals, which gives the ARC 1400 a level of engineering coherence that's difficult to achieve when rims and hubs are sourced from separate manufacturers and assembled together. Every load path through this wheel has been considered as part of a unified system.

The disc-specific construction is not a retrofit. The carbon layup, spoke bed geometry, and overall rim structure are engineered around the braking and torsional forces that hydraulic disc systems generate — forces that differ fundamentally from what rim-brake loads look like. Tubeless-ready from the factory, the ARC 1400 also supports the lower tire pressures and reduced rolling resistance that tubeless setups deliver, without the puncture vulnerability of a tubed configuration. Whether your goal is a fast gran fondo, a criterium block, or a season of mixed-terrain road racing, this wheel is built to stay in the rotation rather than get swapped out when conditions change.

Design Benefits

1. DiCut Carbon Manufacturing: The mechanical resin-removal process that defines DiCut production results in a rim that is lighter and more structurally consistent than standard molded carbon. You're not carrying excess resin mass — every gram of material in the rim profile is contributing to its strength and shape. That translates to a more responsive feel under acceleration and a rim that behaves predictably across its full load range.
2. 62mm Aerodynamic Depth: This rim depth generates measurable aerodynamic benefit on flat and rolling terrain while remaining manageable in variable wind conditions. Deeper wheels can offer incremental gains in a velodrome or a time trial on a calm day, but on a real road — with gusts, corners, and changing gradients — 62mm gives you aero performance you can actually use. It's a depth chosen for versatility, not specification sheets.
3. Disc-Specific Structural Engineering: Disc brakes shift braking force from the rim to the hub and spokes, introducing torsional loads that rim-brake wheels were never designed to handle. The ARC 1400 is engineered from the ground up with those loads in mind — the carbon layup, spoke geometry, and hub design are all calibrated to manage disc-specific stress patterns. The result is a wheel that's more structurally appropriate for modern disc groupsets, not one that simply added a center-lock rotor mount to an existing design.
4. Tubeless-Ready Platform: Running tubeless on this rim allows you to drop tire pressure without risking pinch flats, which improves both rolling resistance and ride comfort on imperfect road surfaces. Sealant in the tire handles minor punctures automatically in most cases, which matters during long training rides or road racing. The ARC 1400 supports this setup without additional conversion hardware.
5. Star Ratchet Hub Engagement: DT Swiss's star ratchet system is one of the most field-proven engagement mechanisms in road cycling. It's fast to engage, mechanically simple, and — critically — designed to be serviced and rebuilt rather than replaced when it eventually needs attention. Riders who put genuine mileage on their equipment will appreciate a hub that can be maintained without replacing the entire axle assembly.

Final Take

The DT Swiss ARC 1400 DiCut Disc 62 is built for road riders who train seriously, race occasionally or regularly, and want an aerodynamic tubeless wheel that doesn't ask for compromises in mixed conditions. It rewards riders who understand what a 62mm disc-specific carbon rim actually offers — and who want a wheel system engineered as a complete, coherent unit rather than assembled from parts. This is a wheel you build around once and rely on consistently.
