Rueda trasera DT Swiss ERC 1400 DiCut Disc 45

The DT Swiss ERC 1400 DiCut Disc 45 Wheel - Rear was built around a question every serious endurance rider eventually asks: why should going fast all day feel like a compromise? The 45mm carbon rim profile sits in a range that genuinely earns its depth — aerodynamic enough to reward sustained effort on flat roads and rolling terrain, yet manageable enough that crosswinds don't become a negotiation. This is a rear wheel designed to disappear beneath you and let you focus on the ride.

ERC stands for Endurance Road Carbon, and the designation carries real meaning in how DT Swiss approached the engineering. The goal wasn't to build the lightest wheel on paper or the deepest rim on the start line — it was to build a tubeless carbon disc wheel that holds up across the full spectrum of roads endurance riders actually encounter. The DiCut name refers to DT Swiss's precision carbon manufacturing process, which optimizes how material is distributed through the rim cross-section to balance stiffness, weight, and impact resistance. The result is a rim that responds when the road tilts upward and tracks cleanly when you're carrying speed into a descent or driving out of a technical corner.

DT Swiss's reputation in wheel manufacturing spans decades, and the ERC 1400 draws on that depth directly. The hub internals reflect the same engineering discipline that has made DT Swiss a benchmark across road and gravel disciplines — precise, durable, and consistent over long mileage. Whether you're deep into a long group ride, grinding solo on a hilly route, or pushing through the back half of a sportive, the ERC 1400 is built to stay composed long after lesser wheels start to feel like they're working against you.

Design Benefits

1. 45mm Depth for Real-World Aerodynamics: A 45mm rim is deep enough to generate meaningful aerodynamic gains on sustained efforts and open roads, but not so deep that handling becomes unpredictable in variable conditions. For endurance riding — where you're managing energy across hours, not just minutes — that balance matters more than chasing peak tunnel numbers.
2. DiCut Carbon Construction: DT Swiss's DiCut process applies precision carbon layup techniques to optimize the rim's structural properties without unnecessary weight. The rim is designed to absorb road vibration across long distances while maintaining the lateral stiffness needed for confident power transfer on climbs and accelerations.
3. Tubeless Ready for Comfort and Puncture Resistance: Running tubeless allows you to drop tyre pressure without the pinch flat risk that comes with inner tubes. Lower pressures improve compliance on rough surfaces — a genuine advantage on the mixed-quality roads that endurance routes often cover — while the sealed system reduces the likelihood of mid-ride flats.
4. Disc-Specific Engineering: Built from the ground up for thru-axle disc brake systems, the hub and spoke geometry are optimized for the braking forces and load distribution that disc setups generate. This means consistent stopping performance in all conditions — wet descents included — without the rim wear that comes with traditional rim brake systems.
5. Broad Drivetrain Compatibility: The rear hub is offered in Shimano and SRAM 11-speed configurations, as well as SRAM XDR, making the ERC 1400 a practical upgrade whether you're running a current groupset or planning ahead for a future build.

Final Take

The ERC 1400 DiCut Disc 45 is aimed squarely at the endurance road rider who trains hard, covers varied terrain, and wants a wheel that performs consistently across all of it — not just on race day. If you're running a disc brake road bike and want a tubeless carbon rear wheel built with DT Swiss's engineering depth behind it, this is a considered, capable choice that earns its place in the build.
