The Duke Baccara WRX 27 SLR2 rim embodies French excellence in the service of gravel adventure and bikepacking. Designed by Duke Racing Wheels in Vendée, this carbon rim with a 27 mm height and 29 mm internal width redefines the balance between lightness, robustness and comfort on the most demanding terrain. Equipped with SLR2 technology (Super Light Road Series 2), it offers a 15% weight saving compared to the SLS generation while improving vibration filtering and impact resistance.

Technical summary

The Baccara WRX 27 SLR2 stands out with its asymmetric profile which increases lateral stiffness and improves spoke tension balance. With a generous internal width of 29 mm, it allows the installation of wide tires (from 36 to 61 mm) to maximize comfort, grip and shock absorption on varied surfaces. Compatible Tubeless Ready and inner tube, it adapts to all setups. Manufactured in high-performance UD carbon with aerospace resin, it benefits from the eco-friendly VFP (paintless) finish which increases gloss and scratch resistance.

Integrated technologies

• SLR2 (Super Light Road Series 2): Exclusive Duke process combining specific resins and optimized carbon layup. Result: 15% weight reduction, increased vertical compliance for extreme comfort, and enhanced impact resistance thanks to a shock-absorbing resin.
• AntiBurp: Duke patented technology that keeps the tire bead perfectly in place even at low pressure, in tight corners or after a puncture, eliminating any risk of slippage or pressure loss.
• VFP (Paintless Finish): Unpainted surface offering exceptional gloss, a more environmentally friendly process and better scratch resistance than traditional finishes.
• Aerodynamic micro-profile: Design optimized by CFD (Computational Fluid Dynamics) simulation that disrupts airflow to reduce turbulence without degrading crosswind stability.
• Asymmetric profile: Offset construction (2 mm offset) that balances spoke tensions on the disc side and opposite side, increasing lateral stiffness while preserving vertical compliance.

Geometry and standards

• Diameter: 28" (700c) - ETRTO 622 mm, road and gravel standard
• Dimensions: 27 mm height × 29 mm internal width × 35-36 mm external width
• ERD (Effective Rim Diameter): 587-589 mm depending on drilling
• Drilling: Available in 24H, 28H and 32H with oriented drillings for perfect nipple/spoke alignment
• Profile: With hooks (hooked) – Duke retains hooks on all its gravel and road rims to guarantee safety at high pressure and better aerodynamics
• Recommended pressure: Up to 4 bar with 38 mm tire, 3.4 bar with 44 mm tire
• Tire section: From 36 mm (1.40") to 61 mm (2.40") for maximum versatility

Uses and performance

Designed specifically for bikepacking, long-distance travel and exploration, the Baccara WRX 27 SLR2 excels on all terrains: gravel, rough trails, unpredictable paths, beach race. Its 29 mm internal width optimizes tire air volume, reducing required pressures and drastically improving efficiency, grip and cornering stability. The wide profile reduces tire roll under the rim during cornering. Maximum system load: 125 kg, making it compatible with gravel e-bikes and tandems. Maximum allowable stress: 1200 N.

Duke Racing Wheels manufacturing and warranty

Duke Racing Wheels, a French brand created in 2011 in Chambretaud (Vendée) by Philippe Jacquinet, designs all its rims in-house with proprietary molds manufactured in Asia under strict quality control. Duke wheels are hand-assembled in France by passionate craftsmen. The brand is also the official Sapim distributor, a guarantee of spoke expertise. Each Duke carbon rim benefits from an extended 3-year commercial warranty and the lifetime Crash Replacement program (replacement at reduced price in case of accidental impact). French artisanal assembly, recognized expertise for over 15 years.

Available variants

• 24H variant: 24-hole drilling - EAN 3701517735177 - For lightweight front/rear builds
• 28H variant: 28-hole drilling - EAN 3701517735214 - Optimal weight/stiffness balance
• 32H variant: 32-hole drilling - EAN 3701517735238 - Maximum robustness for heavy loads and bikepacking

All variants share the same technical characteristics (27 mm height, 29 mm internal width, SLR2 technology, VFP finish). The choice of drilling depends on use: 24H for lightness, 32H for robustness during loaded travel.
