Roata ROATA SPATE FULCRUM RACING 5 C17 CL SHIMANO HG11 #43448

The already best-in-class Racing 5 wheelset goes from high to higher performance thanks to its new designThe same qualities that have made the Racing 5 such a popular wheelset in the past combine new elements in order to make an affordable but also race ready wheel. The 20 spoke design in addition to the 17C wide asymmetric rear rim profile offers remarkable performance in terms of both increased lateral and torsional rigidity as well as increased reactivity. The new design allows for more homogenous spoke tensions and makes for a sturdier, higher performing wheelset.FeaturesRedesigned hubs to increase torsion load resistance.Asymmetric rim profile.Oversize flange.Rim material: Aluminium alloy.Internal width: 17 mm.Rim height: 27.5 mm.20 Straight Pull spokes.Aluminum alloy nipples.TechnologiesAsymmetric rimThe asymmetric rim profile allows better balancing of spoke tensions between drive and non drive side, giving better symmetry to an asymmetric component.Increased efficiency and reactivity are sure to be noted.Hubs and oversize flangeOversized hubs increase wheel stiffness and reactivity.Oversized flange on the drive side provides greater torsional stiffness, and increasing reactivity at each change of the rhythm of the pedal stroke.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. The result is that the spokes:will never lose their initial tension, thus keeping the wheel perfectly reactive and centered;will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.F.I.C. Fulcrum Identification Card100% Handmade qualityRight from its inception Fulcrum® has been marked by feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised by the red “F”.Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company.Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum® makes every day to give you maximum performance and reliability.To ensure the top performance and reliability of its products, each project, for the production stage, must undergo a series of very strict tests that validate what has been conceived and designed up to that moment (fatigue test, crash test, tire burst test, enviroment test, 100% manually assembled and electronically checked).This is why, from its 2012 range, Fulcrum® wanted to supply each wheel with its own Identity Card (ID) which uniquely identifies the wheel and certifies that it has been manually assembled and has passed all tests required by the strict quality protocol.Wide rim techFulcrum®’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28 mm tires, the sizes currently popular.This ensures stability, excellent handling and superior comfort.
