The Fulcrum Red Zone 3 wheels are designed for the widest possible range of users looking for a reliable and durable product to tackle off-road routes, combining fun and performance. They feature the Red Zone Carbon hub and the 24-spoke front and 28-spoke rear solution. The CNC milled aluminium rim has a 19mm profile and a 25mm inner rim base.Aesthetically, these wheels feature a sophisticated finish combining a double glossy and matt surface with laser graphics. Finally, the famous Fulcrum logo, the brand's F on a red square, completes the finish. This graphic element can also be replaced by a black, tone-on-tone reflective sticker included in the packaging._x000D_ The Red Zone 3 are very versatile and suitable for a wide range of uses: training wheels, robust racing wheels or even the perfect base for adventure bikes (Boost Gravel)._x000D_ Technologies_x000D_ Wide Rim Tech: The rims are 4 mm wider, which provides an ideal base for 25/28 mm tyres. This provides stability, excellent handling and a higher level of comfort._x000D_ The cone / cup bearing differs from conventional cartridge bearings in that it works in a way that is perfectly consistent with the forces at play, the weight and the thrusts coming from the frame, because the balls roll on a path positioned opposite these forces._x000D_ Square Milling: A triple-milled structure across the entire profile to reduce the aluminium layers. The technicians then added a three-dimensional milling at the base of the spokes, which reduces the material used and ensures the same reliability because with this particular design, the forces are well distributed on the rim. The triple milling and the "Square Milling" allow the peripheral weight of the rim to be reduced to a minimum and make the wheel extremely responsive._x000D_ Asymmetric Rim: The asymmetry of the rim has been designed to improve rim tension, balancing the forces coming from the brakes and the sprocket cassette._x000D_ 2-Way Fit Ready: This process allows wheels designed to be used with an inner tube to be transformed into Tubeless Ready wheels._x000D_ Characteristics_x000D_ Rim:Material: AluminiumDimensions: 29" (622)Width: 29 mmHeight: 19 mm2-Way FitBrakes: Center Lock DiscSpokes:Material: Double thickness stainless steelProfiles: Rounded, Straight HeadFront: 24Rear: 28Nuts : AluminiumHubs:Front: Aluminium Aluminium, aluminium flangeRear: Aluminium, aluminium flangeBearings : Cone / cup system, adjustableFront axle: 15x110 mm BoostRear axle: 12x148 mm BoostFreewheel body: Shimano MicroSplineWeight: 1610 g_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
