The new Racing 5 DB wheels are the perfect choice for endurance bikes. The lower aerodynamic resistance and decreased stiffness, achieved with the lower 24 mm U-shaped profile, makes them the ideal technical choice for long rideswithout having to worry about climbing, rain or wind, with a consequent saving in energy and increased comfort.In this case to the aluminium rim has seen an increase in the inner channel width, up to 20 mm from the previous model's 17 mm, and the addition of theinnovative 2 Way Fit system, to comfortably fit 25-28 mm tyres, both clinchers and tubeless (tubeless tape installed and valves included). The aesthetics have undergone the same intervention as the Racing 4 DB model, with the new laser etched graphics, ensuring the long life of their striking design.Specifications:- Tyre type: 2-Way Fit™ Ready (Clincher/Tubeless ready)- Tyre size: 700c- Discipline: Road- ASTM Category: 2- Weight: 1660 g- Rim material: Aluminum- Rim material details: Aluminum- Profile height: Low- Rim height: Front and rear 24 mm- Rim width: 25 mm- Inner rim width (channel): 20 mm- Braking system: Disc brake- Braking surface/ Brakes Options: AFS™- Front axle compatibility: HH12-100- Rear Axle compatibilty: HH12-142- Front wheel spokes: 24, Left 16 - Right 8- Rear wheel spokes: 24, Left 8 - Right 16- Spokes: material: Stainless steel- Spokes: profile technology: Rounded, straight pull- Nipples: Aluminum- Front hub: Aluminum, Aluminum flanges- Rear hub: Aluminum, Aluminum flanges- Bearings: Sealed cartridge bearings, adjustable- Others: Lasered + Stickers- Weight limit (system): 120 kg- FWB Version: HG, XDR, N3W Technology:Anti-Rotation System™:- This new system raises the concept of spoking to a new level of performance for road bike and triathlon wheels ( and mtb too)The Fulcrum® engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole.
