DUKE Baccara X 48 SLR2 Rim - 28" | Carbon | Tubeless | Disc - 24 Holes - UD

The Duke Baccara X 48 are carbon rims that are suitable for use on the road, for long-distance rides and competitions and are approved by the UCI. They are versatile on all types of roads and have an internal width of 23 mm with a height of 48 mm.

The SLR2 technology reduces the weight by 45g compared to the previous model. This process enables better filtering of vibrations. The rim profile has been redesigned to improve aerodynamics and stability in all wind conditions.

The outer width has been increased to 29.4 mm, has a new UV shape and reduces drag.

The rim holes are off-center (2 mm offset), allowing the spoke shield to be closed more tightly. This makes the rim more stable and increases the lateral stiffness of the wheel. The spoke tension between the two layers is more balanced, which guarantees better durability of the wheel. The result: more stiffness and more durability.

The wider hook width of 23 mm gives the tires more volume and improves comfort and grip without sacrificing performance.

Technology:

SLR2 (Super light road series 2)

A design optimized to the requirements of road and gravel bikes:

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

Aero

Aerodynamic optimization through CFD (Computational Fluid Dynamics)

• Optimized transition between tire and rim to reduce air resistance
• Greater stability in crosswinds
• Compatible with wide tires without sacrificing rolling resistance efficiency

Hooked

Hooked Rim design

• Optimized for the pressure of road and gravel tires
• Ensures secure hold of the bead
• Larger inner width offers aerodynamic advantages

DRC (Dynamic Response Comfort)

Controlled vertical flex and rebound

• More dynamic handling when shifting weight and cornering with bumps
• Increased comfort on rough terrain
• Less energy loss, more speed and efficiency

Optimized inner width

Maximizes tire volume and performance

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

VFP (Varnish Free Process)

A paint-free coating process

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

Offset

Asymmetrical lacing

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

Tubeless Ready

Tubeless-Compatible rim design

• Compatible with UST and Tubeless Ready standards
• Also compatible with tubular tires
