Deda RS4 DB Carbon Disc Tubeless Road Wheels – Aero Performance Set

The Deda RS4 DB Carbon Disc Tubeless Wheels set a new benchmark in the world of high-performance road cycling components. Weighing just 1340g per pair, these wheels are engineered for riders who demand the perfect balance of lightweight design and aerodynamic efficiency. Crafted with a 38mm rim height and a 26mm external width (19mm internal), the RS4DB wheels excel in delivering speed and responsiveness on every terrain, whether climbing steep hills or sprinting on flat roads.

Built with a full carbon rim that combines High Modulus Carbon fibers in UD and 3K weaves, the wheels feature a unique layup pattern that reinforces the spokes' nipple areas while reducing material thickness elsewhere. This innovative internal wave pattern not only cuts down on weight but also enhances rolling speed and reduces rotational inertia, making acceleration easier and more fluid. Additionally, the internal alloy nipples with a self-locking ABS system ensure superior aerodynamics and prevent loosening over time, reducing maintenance needs and improving reliability.

The redesigned RS hubs bring significant improvements over their predecessors, weighing only 307g per pair and offering an 80g weight saving compared to the previous SL generation. Smaller in size by 20%, these hubs boast aerodynamic flange designs that minimize drag on both front and rear wheels. The Rifling machining enhances airflow stability by generating a downforce effect that keeps the bike stable at high speeds. The rear hub’s innovative 2 ratchet system delivers lightning-fast engagement and flawless power transfer, all while being 16% lighter and maintenance-free.

Designed for compatibility with a wide range of drivetrains including Shimano, Sram, and Campagnolo, and equipped with ceramic bearings and Shimano Centre Lock disc brake mounts, the RS4 DB wheels combine cutting-edge technology with practical features for the avid cyclist. The package includes tubeless rim tape, tubeless valves, a wheelbag, a centre lock lock-ring, and a small bottle of freehub lube, ensuring you have everything you need to hit the road with confidence.

What It’s Good For

• Providing lightweight performance for climbing and fast acceleration
• Enhancing aerodynamics to improve speed on flat and rolling terrain
• Reducing maintenance with self-locking nipples and a maintenance-free hub design
• Offering compatibility with multiple drivetrain systems for versatile use
• Improving stability at high speeds thanks to the aerodynamic hub design
• Delivering quick and efficient power transfer through the advanced 2 ratchet rear hub system
• Supporting tubeless setups for better puncture resistance and ride comfort

What It’s NOT Good For

• Use with rim brake systems, as these wheels are designed specifically for disc brakes
• Off-road or heavy-duty mountain biking, since these wheels prioritize road performance
• Riders looking for extremely deep rims designed primarily for time trials or triathlons
• Compatibility with non-standard axle sizes outside 12x100mm front and 12x142mm rear

Frequently Asked Questions

Are these wheels compatible with all disc brake road bikes?
Yes, the RS4 DB wheels use Shimano Centre Lock disc mounts and are compatible with thru-axle sizes 12x100mm front and 12x142mm rear, which fit most modern road disc brake bikes.

Can I use these wheels with tubeless tires?
Absolutely. The RS4 DB wheels come fitted with tubeless rim tape and valves, making them ready for a tubeless setup that offers better puncture resistance and a smoother ride.

How do the hubs improve performance compared to older models?
The hubs are lighter by 80g, 20% smaller, and feature aerodynamic flanges with a rifling design that improves airflow and stability. The rear hub’s 2 ratchet system also provides faster engagement and maintenance-free operation.

What drivetrain systems are compatible with these wheels?
They support 10/11/12-speed Shimano, 12-speed Sram XDR, and 9/10/11/12/13-speed Campagnolo systems, ensuring broad compatibility with popular groupsets.
