GRC Design Philosophy

GRC stands for “Gravel Carbon.” Unlike road carbon wheels that pursue extreme lightness and aerodynamics, the GRC 1400’s design prioritizes the following:

Durability

The 28 rear spokes (4 more than road carbon wheels) ensure structural strength on gravel roads. DT Swiss Competition spokes are stronger than Aero Comp spokes and are specifically used on the rear wheel, which bears greater loads.

Serviceability

Using standard-spec DT Swiss spokes rather than proprietary or carbon fiber spokes ensures that spare parts are available at any DT Swiss dealer worldwide. This serviceability is especially crucial during long-distance gravel adventures.

Tire Compatibility

The 24mm inner rim width paired with a hooked rim design is compatible with a wide range of tires from 28-50c. The hooked rim does not restrict tire types, allowing Clincher, Tubeless, and even inner-tube setups.

Ratchet EXP Performance in Gravel Conditions

Reliability

The reliability of the Ratchet EXP ratchet system in gravel conditions is its greatest advantage. The simple structure (two ratchet rings + one spring) means it is less prone to issues in sand, dust, and mud. Even when maintenance is needed, disassembly and cleaning are very straightforward.

Water and Dust Resistance

The sealing design of the DT Swiss 240 EXP hubs performs excellently in gravel environments. After crossing water and muddy sections, the hub internals typically remain clean.

Easy Maintenance

During long gravel adventures, you may find yourself far from any bike shop. Maintaining the Ratchet EXP requires only a star-shaped wrench, which is a huge advantage for emergency repairs in remote areas.

Real-World Riding Experience

Stability on Gravel Roads

The GRC 1400 feels reassuringly stable on gravel roads. The 28 rear spokes provide ample lateral stiffness, and there is no feeling of instability even when cornering at speed over loose gravel.

Performance on Paved Sections

The 35mm rim depth offers some aerodynamic advantage on paved roads, and the 1,460g weight is reasonable for a gravel carbon wheelset. While it doesn’t match the CADEX AR 35’s 1,350g, the extra 110g buys higher durability and easier maintenance.

Tubeless Installation

DT Swiss’s Tubeless Ready rim profile makes installing gravel tires very smooth. The 24mm inner rim width allows 40-45c gravel tires to mount easily, and air retention is excellent.

Experience on Taiwan’s Gravel Routes

On Taiwan’s common riverbed gravel and industrial roads, the GRC 1400 performs steadily. The 28 rear spokes demonstrate good durability when absorbing impacts from larger rocks, and the DT Swiss 240 hubs continue to spin smoothly after water crossings.
