From the manufacturer's official website:
"The wheel that stands out thanks to its high manufacturing quality and low price. The ideal choice for everyday riding."
The Fulcrum® range takes on a red tinge with the introduction of the new Racing7 entry-level wheelset - high-quality wheels at an affordable price. With Racing 7, Fulcrum® offers light, high-performance wheels which are reliable over time.
Racing7 wheels have an aluminum rim with a height of 24 mm and aerodynamic profile and machined braking surfaces with wear indicator. Hubs are oversize, flanged, and turning on sealed cylindrical bearings.
Twenty 2 mm spokes are radially laced on the front wheel to improve the bike's aerodynamics. The rear wheel, on the other hand, has 24 spokes laced according to Fulcrum's renowned 2:1 Two-to-One™ geometry to improve transmission of the athlete's power.
Racing 7 wheels are available in black or red color versions and are compatible with Campagnolo®, Shimano® and Sram® drivetrains.
2:1 Two-to-One™ Spoke Ratio
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.
As a result there are two spokes which carry out the function of one, slackening and torsion are limited and the transfer of the athlete’s power is much more effective. Also, thanks to this system, spoke tensions are balanced more evenly between drive and non-drive sides and the fatigue life of the rim, hub and spokes is lengthened.
Dynamic Balance™
Unlike carbon rims, all the aluminum rims are joined. The joint, though indispensable, entails a concentration of material in a single point and creates an annoying “jump” effect at speed. Fulcrum® has eliminated this annoying problem with the Dynamic Balance™ patent.
The concept is simple and elegant: balance the mass of the joint with a mass of the same weight. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint. For entry-level models, Dynamic Balance™ is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.
