DUKE Baccara RX 42 SLR2 Rim - 28" | Carbon | Tubeless | Disc - 24 Holes - UD satin

The Baccara RX rims represent the latest generation of DUKE All Road carbon wheels, lighter and stronger for faster riding, perfect for both leisure and competition, they are UCI APPROVED.
They are suitable for both Road and Gravel use, thanks in particular to their 25mm internal width, which guarantees good versatility.

The Baccara RX 42 rim benefits from the latest Duke SLR2 manufacturing technology, which combines comfort, lightness and strength: the "MAGIC MIX":

• EXTREME COMFORT thanks to the use of specific resins and processes to filter out some of the vibrations.
• ULTRA-LIGHT rim with a new lay-up and a new combination of fibers enabling a weight reduction of 50g compared to a conventional lay-up.
• FIREPROOF STRENGTH thanks to shock-absorbing resin. The range of rim profiles (27, 36, 42, 48 and 56mm) gives you a wide choice to suit your needs.

Aerodynamics have not been forgotten, with a reworked profile to improve air penetration and stability in all wind conditions, essential for performance. The rim retains the use of hooks to ensure safety above all else, whatever tire is used. Its unique VFP gloss finish is scratch-resistant and more environmentally friendly. The asymmetrical profile balances the tension between the two sides of spokes, ensuring greater durability and wheel stability. While the 25mm width between hooks gives a tire greater volume, improving comfort and grip without sacrificing performance.

Technology:

SLR2 (Super light road series 2)

A design optimized for the demands of road and gravel riding:

Aerospace-grade resin and optimized carbon fiber lay-up
Up to 10% lighter and stronger than the previous SLR1 version
Tuned vertical compliance for more comfort and responsiveness

Aero

Aerodynamic optimization through CFD (Computational Fluid Dynamics) 

• Optimized tire-to-rim transition to reduce aerodynamic drag 
• Greater stability in crosswinds 
• Compatible with wide tires without compromising rolling efficiency

Hooked

Hooked rim design 

• Optimized for road and gravel tire pressures 
• Ensures secure bead retention 
• Wider internal width offers aerodynamic benefits

DRC (Dynamic Response Comfort)

Controlled vertical flex and rebound 

• More dynamic handling during weight transfers and bermed corners 
• Increased comfort on rough terrain 
• Reduced energy loss, more speed and efficiency

Optimized Internal Width

Maximizes tire volume and performance 

• Enables lower pressures without sacrificing rolling efficiency 
• Controls tire deformation for greater stability 
• Improves control and comfort on all terrains

VFP (Varnish Free Process)

A varnish-free finish process

• Reduces VOC emissions and carbon dust during production
• More scratch-resistant surface
• Naturally glossy finish

Offset

Asymmetrical spoke lacing

• Balances spoke tension on both sides
• Improves lateral stiffness, stability, and long-term durability
• No added weight

Tubeless Ready

Tubeless-compatible rim design 

• Compatible with UST and Tubeless Ready standards 
• Also compatible with tube-type (clincher) setups
