DUKE RIM CORE GR30

Core GR 30 forms the third tier of our carbon gravel range.

It sits below Sierra, our Elite gravel family, and Baccara WRX, our Performance offering.

Its philosophy follows the Core principle: retain the dimensions, useful technologies and build quality that make a good wheel, within a simpler and more accessible construction.

With a 30 mm depth, 380 g per rim and a 26 mm internal width, Core GR prioritises versatility, control and ease of use. It accepts tyres from 28 mm to 2.4 inches, with an optimal range from 38 mm to 2.2 inches.

From 1,346 g per pair, it is suited to riders discovering carbon gravel, bikepacking, long rides or using it as a second training wheelset alongside Sierra or Baccara WRX.

The 1.5 mm Offset creates an asymmetric spoke bed that better balances tension between the two sides of the wheel. This geometry improves lateral stiffness, stability and reliability without adding weight. On gravel terrain, where loads and impacts constantly vary, this balance contributes to precise and durable behaviour.

Core GR uses a Hooked construction. The bead hook provides mechanical tyre retention suited to gravel pressures and broad compatibility with current standards.

AntiBurp complements the system: its internal ridges lock the tyre beads in place, limit air loss under side loads and improve retention when the terrain becomes more demanding.

Tubeless Ready compatibility allows pressure to be adjusted in search of grip, comfort and control. The rim is compatible with UST and Tubeless Ready standards, supplied with DUKE rim tape and a tubeless valve, and can also be used with an inner tube.

Core GR 30 therefore offers a straightforward take on carbon gravel: versatile, reliable and accessible.
