Fulcrum Racing 5 C17 wheelset

The already best-in-class Racing 5 wheelset goes from high to higher performance thanks to its new design

The same qualities that have made the Racing 5 LG such a popular wheelset in the past, combined with 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.

Technologies

RDB™ RIM DYNAMIC BALANCE
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.

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 centred
• 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 CARD - 100% HANDMADE QUALITY
Right 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.

WIDE RIM TECH
Fulcrum®’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 25/28mm tyres, the sizes currently popular. This ensures stability, excellent handling and superior comfort.

DIFFERENTIATED RIM HEIGHT
Two different heights for front and back. A bigger challenge in construction, but necessary to achieve the very best. The lower front wheel improves handling, limiting weight to a maximum and also mass involved when turning and relaunching. The rear rim is higher and more solid, to transmit all the power to the wheel and increase stability.

OVERSIZE FLANGE
The Oversize Flange was developed from the need to create a system to transmit every watt to the ground without dispersion, stiffening the wheel system where necessary, without having to add spokes or superstructures that increase weight. The oversize flange uses physics to solve the problem. It increases dishing and enables spokes to be shortened. Doubling the spokes creates a balanced system that is excellent at transmitting torque.
