Fulcrum Racing 6 C17 rear wheel

The Racing 6 is an entry level wheel with a race-ready soul

The same Fulcrum quality and performance as the rest of the line with advanced characteristics such as a differentiated profile and Spoke Dynamic Balance technology.

Fulcrum engineers have pushed the quality of this road bike wheels even further incorporating an asymmetric rear rim that increases performance in terms of lateral and torsional rigidity as well as reactivity. The rim is 17C, as the new standard nowadays.


Features

  • Redesigned hubs.
  • Oversized flange.
  • Rim material: Aluminium alloy.
  • Internal width: 17 mm.
  • 20 J-Pull spokes.
  • Rim height: 27.5 mm.
  • Aluminum alloy nipples.


Technologies

Asymmetric rim
The 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.
Differentiated road bike rims height: 24 mm at the front to provide optimal handling; 27,5 mm at the rear for transmitting all your power to the wheel.

Hubs and oversize flange
Oversized flange on the drive side provides greater torsional stiffness, and increasing reactivity at each change of the rhythm of the pedal stroke.

2:1 Two-to-One™
When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension.
This results in undesirable flex of the whole wheel and an unavoidable loss of energy. Fulcrum® has solved this classic cycling problem with its 2:1 Two-to-One™ Spoke Ratio patent, by doubling the spokes in the critical zones.

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 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.
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.
