BENEFITS OF GRAPHENE 2.0 IN CARBON WHEEL APPLICATIONS
The addition of this nano-technology material results in a faster,
stronger, more resilient carbon-composite material. Similarly to tires,
when applied to wheels, Graphene filled the holes in between the
carbon molecules bonding with them. As a consequence, results
displayed that carbon wheels increased lateral stiffness, improved
resistance, became lighter and boosted heat dissipation. Moreover,
one of the key findings was that Graphene-enhanced carbon wheels
for tubeless tires are now able to be used at higher air pressures and
experience enhanced braking in all conditions.
All Qurano and Race tubular wheels have graphene-enhanced fullcarbon
rims that far out-perform today’s best. This is the future of
carbon wheels. GRAPHENE 2.0-enhanced composites have up to
50% improved material properties. Tests carried out by Vittoria R&D
engineers, confirmed by external laboratories, found that introducing
graphene into the rim’s carbon-fiber matrix has a great positive
GRAPHENE 2.0 reduces temperature build-up
GRAPHENE 2.0 increases material strength by up to 20%
GRAPHENE 2.0 improves lateral stiffness
GRAPHENE 2.0 enables further weight reductions for future products by up to 150 grams/per wheelset
By balancing spoke angles on both left and right sides of a
wheel, an asymmetric rim offers a laterally stiffer wheel. This
is crucial on disc brake wheels, where the brake disc mount
displaces the hub flange to the hub center. The 2.5 mm offset
from center on asymmetric rims minimizes differences in
spoke tension and equalizes spoke-lacing angles, making
for a stiffer, more stable wheel.
VITTORIA SWITCHIT® TECHNOLOGY
All road wheels are built on a hub designed and developed
by Vittoria. Produced to meet the highest possible standards
of quality, Vittoria’s SwitchIt® hub features industry-proven
parts for supreme performance, time and time again. The
spokes, whether round-section or bladed, are straight-pull
and specially produced for Vittoria. Straight-pull spokes
have been specifically chosen over J-bend spokes as they
offer superior strength and are thus less prone to failure.
Rear wheel hubs feature an oversized drive-side flange, with
spokes laced in a 2:1 ratio. This creates the perfect balance
in spoke tension on each side of the wheel, which makes for
an ultra-responsive ride.
Most of Vittoria’s road wheel options feature the SwitchIT®
freewheel system. Cassettes mount on a freewheel body
that can be removed quickly and replaced without the use
of tools. This allows for simple gear ratio adjustments to
suit the conditions. Vittoria’s SwitchIT® technology works
seamlessly with Shimano, Campagnolo or SRAM cassettes.
