Fulcrum Rapid Red 3 DB Gravel Set 27.5" 12x100/12x142mm HG 8-11-speed Disc CL Clincher TLR black

On the road along the B-roads, on hidden and little-used paved roads or off-road, with a bike with curved handlebars and wide tires - this is what Fulcrum knows best.

The new Rapid Red 3 DB wheelset is particularly well suited for rides on changing terrain and has been redesigned from the tip up. It is made entirely of aluminum and features a weight-saving CNC machined rim, with a jaw width of 24 mm, which fits perfectly with more modern frames with plenty of air for tire clearance.

The renowned 2-Way Fit Ready design allows mounting both a tubeless tire and a clincher tire, ensuring maximum compatibility with the various types of tires available on the market. The freedom to choose between the diameters 700C (from a width of 30 mm) and 650B completes the versatile range. The right balance between size of the wheel and type of tire makes this wheel model incredibly fast on asphalt or unstoppable on difficult gravel roads: It belongs to the category ASTM 2 impellers.

2:1 TWO-TO-ONE SPOKE RATIO - Disc Brake
At the moment when the rider pedals at full power, the rotation of the sprocket set causes the spokes on the freewheel to give way with subsequent loss of tension in the rim. This causes an excessive bending of the whole and this inevitably means a loss of energy.
Fulcrum has solved this classic problem in cycling with its patent 2:1 Two-to-One Spoke Ratio, that is, by doubling the number of spokes in the critical areas.

RDB Rim Dynamic Balance
The concept is simple and ingenious: balance the mass of the rim joint with a mass of equal value positioned exactly opposite it

Wide Rim Tech
The Fulcrum F E department, following the requests of the racing teams, worked to create rims with a greater width in relation to the past, from about 4 mm more than the previous ones.
This technical choice allows to offer the ideal support base for 25/28 mm tires, the preferred sizes today. In this way, stability, optimal handling and high comfort are guaranteed.

Cup & Cone
The slide and cone bearing differs from the classic cartridge bearings in that it works perfectly aligned with the corresponding forces, weight and thrusts coming from the frame, since the balls run on a groove positioned in direct opposition to these forces.
