The DUKE Lucky Star HD 6TERS rim embodies the excellence of French engineering in mountain bike wheels. Made from high-quality Dynamal aluminum, it stands out with its modern asymmetric hookless profile and Heavy Duty construction, offering an optimal balance between lateral stiffness, impact resistance, and lightness. Developed in collaboration with champions like the Absalon brothers and Perrin-Ganier, this rim adopts the revolutionary 6TERS concept: differentiated front/rear profiles to maximize grip, handling, comfort, and efficiency on all terrains, from XC racing to Down Country and aggressive Trail.

6TERS Concept: Differentiated profiles for maximum efficiency

The 6TERS concept ("sisters") is based on an innovative philosophy: the requirements of a front and rear wheel are not identical. The front rim prioritizes grip, lightness, stiffness, and handling, while the rear wheel focuses on comfort, robustness, and power transmission. DUKE offers differentiated internal widths: 28mm/26mm or 30mm/28mm, allowing you to pair a wider rim at the front for better cornering support and a reduced section at the rear to optimize efficiency and durability.

Heavy Duty technology and advanced construction

• Dynamal aluminum: Premium alloy offering exceptional stiffness-to-weight and strength-to-weight ratios, for increased durability even on technical terrain.
• Asymmetric profile with offset (2.1-2.3 mm): Off-center drillings allowing for a tighter spoke umbrella angle, increasing lateral stiffness and balancing tensions for optimal longevity.
• Hookless walls: Structural reinforcement while reducing weight; perfect retention of the tire bead regardless of pressure (anti-burp system), eliminating any risk of tire unseating even in the tightest corners.
• Modern low geometry: Reduced rim height (17-18 mm) promoting responsiveness and aerodynamics while maximizing internal air volume for more comfort.

Available variants

• 26mm variant: Internal width 25.5mm — EAN 3701517700588 — Ideal for rear wheel with 1.90"-2.40" tires
• 28mm variant: Internal width 27.5mm — EAN 3701517700595 — XC/Trail versatility, front or rear wheel
• 30mm variant (28 holes): Internal width 29.5mm — EAN 3701517700731 — Preferred front wheel, maximum grip, tires up to 2.60"
• 30mm variant (32 holes): Internal width 29.5mm — EAN 3701517700748 — Same profile, additional reinforcement with 32 spokes

Each variant offers optimized ERD (Effective Rim Diameter) for precise lacing: 604mm for the 26mm, 602mm for the 28 and 30mm. Drilling available in 28 or 32 holes to suit all mounting configurations.

Tubeless Ready versatility and performance

Compatible Tubeless Ready (requires DUKE rim tape and tubeless valve) or traditional mounting with inner tube. Recommended tire sections vary depending on width: from 1.35" to 2.60", with a maximum pressure of 3 bars for a 2.10" tire. The maximum authorized system weight is 110 kg (rider + equipment), ensuring safe intensive use.

Standards and warranties

Manufactured in France at the DUKE factory in Chanverrie (Vendée), this rim benefits from a legal warranty of 2 years. DUKE owns its manufacturing tools and processes, guaranteeing optimal traceability and quality. The controlled weight (approximately 420g for the 30mm version, up to 595g depending on configurations) testifies to the excellence of the design and materials used.

Designed for demanding riders

The Lucky Star HD 6TERS is aimed at cyclists looking for a robust, light, and high-performance rim for XC racing, aggressive XC, Down Country, and Trail. Its wide profile promotes increased air volume, improving comfort, cornering grip, and rolling efficiency. Combined with premium hubs (DT Swiss, Chris King, Hope, Tune…) and high-end spokes (Sapim, Alpina), it provides the ideal foundation for a custom handbuilt wheelset, designed for competition as well as marathon rides.
