The DUKE World Runner X 25 rim in limited edition silver represents the excellence of French manufacturing for gravel, allroad and bikepacking. Designed and tested in Vendée, this brushed anodized Dynamal aluminum rim offers a perfect balance between lightweight (from 465 g), lateral stiffness and exceptional durability. Its optimized asymmetric profile and 25 mm internal width make it a preferred choice for demanding cyclists, whether competitors or long-distance adventurers.

Artisan design and exclusive technologies

DUKE Racing Wheels is the exclusive owner of the manufacturing tools for this rim, guaranteeing total quality control and technical innovations. The World Runner X 25 benefits from several cutting-edge technologies:

• Dynamal alloy: 50% stronger than conventional 6061-T6 aluminum, this pure magnesium-silicon enriched alloy with confidential metal offers increased resistance to impacts and stress without loss of fatigue resistance
• AntiBurp system: two internal ridges firmly lock the tire bead, eliminating any risk of tire rolling or pressure loss even in hard cornering, at low pressure or after puncture
• Polyaxial drilling: optimized orientation of spoke holes ensures perfect alignment of nipples and spokes, significantly extending the lifespan of the assembly
• Asymmetric profile with 2 mm offset: compensates for hub flange offset caused by modern disc brakes and cassettes, rebalances spoke tensions and increases lateral stiffness without adding weight

Geometry and standards

• Diameter: 700C (ETRTO 622 mm), road and gravel standard
• Internal width: 25 mm, optimized for tires from 28 to 61 mm (1.10" to 2.40")
• Profile height: 25 mm, balance between aerodynamics and comfort
• ERD (Effective Rim Diameter): 589 mm for precise spoke calculation
• Asymmetric offset: 2 mm, offset spoke holes to close the spoke umbrella
• Maximum pressure: 4.5 bar with 40 mm tire, compatible tubeless or inner tube
• Maximum system load: 120 kg, proven robustness for bikepacking and tandem

Available variants

The World Runner X 25 silver is offered in several drilling configurations to suit all setups:

• 24 holes: Lightweight configuration for front or rear wheels with high-quality hubs
• 28 holes: Optimal versatility, ideal stiffness/weight compromise (version EAN 3701517709345)
• 32 holes: Reinforced setup for heavy loads, touring, tandem or cyclists >100 kg

Compatibility and assembly

This hooked rim design rim ensures secure bead retention across the entire gravel and road pressure range. Compatible with disc brakes only (Center Lock or 6-bolt depending on hub), it accepts tubeless Ready tires with DUKE 28 mm rim tape and 44 mm valves, or traditional inner tube setup. The brushed anodized silver finish offers premium aesthetics and long-lasting protection against oxidation.
