efferre – Carbon NB45

efferre Carbon NB45 Wheelset

Theefferre Carbon NB45is a 45mm deep-section carbon wheelset designed to balance aerodynamic efficiency, low weight and predictable handling. Its versatile rim profile suits road racing, gran fondos, endurance rides, triathlons and everyday performance training.

The full carbon construction provides responsive power transfer, while the moderate rim depth supports stable handling in changing wind conditions. In addition, the tubeless-ready design allows riders to use modern tyre setups with lower pressures, improved grip and greater riding comfort.

efferre Carbon NB45 Aerodynamic Performance

The 45mm rim depth offers an effective balance between aerodynamic speed and manageable weight. It helps reduce drag on fast roads while remaining responsive during climbs, accelerations and repeated changes of pace.

This profile also provides more predictable handling than many deeper carbon rims. Therefore, the wheelset performs effectively across flat roads, rolling terrain and exposed routes.

The aerodynamic shape helps riders preserve momentum during solo efforts, road races and fast group rides. At the same time, the moderate depth makes the wheels practical for regular training and mixed-terrain events.

Lightweight Carbon Construction

High-modulus carbon fibre gives the rims a strong stiffness-to-weight ratio. This construction helps transfer pedalling force efficiently during sprints, climbs and hard accelerations.

Each rim weighs approximately 470 grams. As a result, the wheelset remains responsive when accelerating out of corners or increasing speed on steep gradients.

The carbon structure also helps control vibrations from rough road surfaces. Consequently, riders can enjoy a smoother and less fatiguing experience during longer events and endurance rides.

Tubeless-Ready Rim Design

The rims support tubeless-ready tyres and can also accept compatible clincher tyres with inner tubes. A tubeless setup allows riders to use lower tyre pressures without the same risk of pinch flats associated with traditional inner tubes.

Lower pressures can improve grip, comfort and control on uneven road surfaces. Moreover, tubeless systems may reduce rolling resistance when riders use compatible tyres and install them correctly.

Always check tyre compatibility, rim tape, valves and sealant before installation. Follow the tyre and component manufacturers’ instructions when setting up the wheels.

Wide Rim Profile and Tyre Support

The wide rim profile supports modern road tyres ranging from approximately 25mm to 40mm, subject to tyre, rim and frame compatibility.

A wider rim can improve tyre support during cornering and help create a more stable tyre shape. Therefore, riders may experience better control and a smoother ride quality.

The broad tyre range also increases the versatility of the wheelset. Riders can select narrower tyres for fast road use or wider options for comfort, endurance riding and rougher surfaces.

Disc Brake Road Performance

The wheelset uses a disc-brake-specific rim design. Since the rim does not require a braking surface, the carbon structure can focus on aerodynamic performance, stiffness and ride quality.

Disc brakes also separate braking performance from the rim surface. As a result, the wheels maintain a clean appearance and work with compatible hydraulic or mechanical disc-brake systems.

Before installation, confirm axle standards, rotor interfaces, cassette compatibility and frame clearance.

Versatile Road Applications

The NB45 suits riders who want one carbon wheelset for several types of road cycling. Its 45mm depth provides aerodynamic support for fast rides while maintaining the responsiveness required for rolling terrain and climbing.

The wheelset works well for road races, criteriums, sportives, gran fondos, triathlon events and performance-focused training.

Its combination of speed, low rim weight and tubeless compatibility makes it a practical upgrade for riders seeking versatile carbon performance.
