The road test

We tried these very special wheels for long time, finding out fully merits
and defects. Made with great
care,
not the side by criticism about processing and finishing. The
carbon-rays are very resistant to the stresses of tension and
compression, but suffer any side strokes, so the wheels are equipped
with bags and it is good to be careful especially in the transport
machinery. Although essentially aluminum wheels, it must be dealt
with the same delicacy and attention of carbon wheels. We would have
preferred, however, that the same technology "TraComp" had also
applied to the rear wheel in the side bodice free-wheeling. Frankly
there explain why, established the goodness of the new technology,
this has not been used in full to the rear wheel, sending "retire"
definitely the old spokes and overcoming any technical problems that
have, so far, prevented the application. Always with a pair of
wheels at the top, we would welcome a series of locks more
performance;
nothing serious, even in this case, but we believe that these wheels
had also earned locks dedicated and lighter, even just a few gram.
The magnet integrated on a range of front wheel is very convenient
because avoids damage to the beam, but once housed the height should
be better secured with adhesive tape or a drop of silicon. For the
road test, the more times we happened that the magnet lost its ideal
location, and then blocking the cyclocomputer, because of
disconnections asphalt and vibration that plan, they plan to move
the magnet toward the center of the wheel; enough, however, a round
of adhesive tape and everything is resolved, the problem also has
occurred only when we have come very disconnected roads. Good ring
the closing package pinions Campagnolo, made light alloy. The
assembly of the tyre is simple, but these wheels
should be enhanced with tubular and roofing with very light and
absolutely with inner tubes latex. Mounted everything hand and right
now shows the character of these wheels. The lightness ago taken
immediately raises the speed, aided by high rigidity that prevents
or minimizes the lateral bending of the circle allowing to transmit
the power of pedalling on the whole, without dissipating energy;
indeed rays carbon and their mounting flange hub between circle and
seem truly effective and valid increasing significantly and
appreciable rigidity of the wheel. With asphalt sorted these wheels
run away fast burning with acceleration due to stiffness, lightness
and the quality of bearings, though, to tell the truth, we would
have preferred the adoption of ceramic bearings to heighten even
more performance. They are very sliding, but not very much, that is we
would have expected a glide even better, given the type of wheels,
compared to that put into evidence. Examining other words, this
single aspect are not above the competition,
but
are still at the level of the best competitor, it is easy to reach
high speeds quickly and keep them for long. But the diameter sustained rays carbon creates an aerodynamic noise, a sensitive ear
can perceive already starting from 60 km/h, which increases
proportionally with increasing speed. The aerodynamics of these
wheels, then, is not perfect. Without doubt the "culprits" are rays
carbon because, in fact, the noise is more noticeable on the front
wheel on the back, which has only 10 in composite beams. This,
however, does not mean that they are slow wheels at high speeds. We
tested in comparative tests with these wheels and other competitors
on equal terms have always expressed values maximum speed similar,
if not better to the other products. Moreover, they do not want to
be wheels for pure speed, but wheels for mixed routes, nervous and
the ascent. And it is on these roads that the wheels R-Sys enhance
demonstrating their absolute goodness. That good behavior, flat with
asphalt in order should be noted that disconnections on the
stiffness of composite beams and the same structure of a minimum
wheel prevents absorption of shocks
and vibrations, sending every jolt the frame. They are not
comfortable wheels, and then, it is better for this are properly a
pair of tubes that can better absorb the shocks of the road,
returning a minimum of comfort. On the other hand, if you want a
really rigid wheel should also put a lower capacity to absorb
vibration asphalt, however with two tubular quality you can "smooth"
this critical aspect. Excellent, however, the behavior in the
presence of lateral wind, even strong, where these wheels
approaching greatly to the behaviour of a wheel round-ray is normal
and far better wheels with spokes aluminum plates. But after good
behavior in raises and ondulating paths, we as a hard climb where
these wheels are still winning show, allowing a fast pace, a great
facility in reviving the action outside the curves or out set.
Going downhill appear another time the aerodynamic rustle, but the speed
edge does not seem affected, at least not so obvious as in our
benchmark tests these wheels were always much faster in terms of
maximum cast, although only a few tenths of km/h. The downhill,
however, if you want to be fast, be "attacked" making the most of
the
positive aspects of these wheels; exploiting their rigidity and
lightness can revive the action outside the curve quickly reaching
high speeds, conversely can be reached Maximum speed less than
competitors, but the difference is limited to a maximum of 2 km/h.
A conduct "aggressive", and then allows you to be very fast downhill,
especially if it is a technical descent, with tight curves and high
speed held up for a few moments. Here these wheels still return to
theirs, with outstanding performance. The runway braking corrected,
then, allows a perfect and safe braking extolling the skills of
braking and helping to make even more winning these wheels in the
most daring and techniques. Excellent Finally, the decision to
differentiate between front wheels (lower and narrow) and rear (highest
and off): especially in the wet you can have a bigger footprint on
the ground in the rear tyre output curve and the profile of circle
earlier ease placement cornering, making them very fast.
Conclusions

The Mavic R-Sys are dimostrated good wheels, maybe the best ever in the
field of aluminium circles. The cure is obvious constructive, as
well as technological innovation. We would have preferred that Mavic
"dare"
a little more marrying entirely new technology and taking the locks
even more refined than, however excellent, already adopted.
Particulars
and notes from those seeking the best ever. In practice these wheels
have exhibited obvious qualities of lightness and stiffness, with a
rolling, that unless there is the absolute top is excellent. A sign
that the new Mavic technology is not just marketing, but healthy
substance. Although many trail miles, including roads in order not
perfect, we have not had incidents and even though it is early to
make a definitive judgement, we do not believe that these wheels and
spokes in particular have an "Achilles' heel" reliability. Besides
studies and tests carried out by long Mavic first put into
production, as well as his long experience in the processing and
production
of composite wheels, bring away from any doubt the reliability of
these wheels. They exalt uphill, where there are slight and fast, and
mixed routes ondulating, where allow changes very fast rhythm and
acceleration. Going downhill can be quickly, but we should be able
to exploit with continual raises out of the curves. Good behaviour
during braking, while little is the comfort because of their
rigidity of the wheels.
The price
The suggested price to the public (including VAT) is Euro 1.100,00
are among the best aluminum wheels currently on the market, with the
only rays carbon. The benefits are expressed in absolute good and
justify the price of a pair of wheels at the time only.
Is suitable for
Athlete: are wheels on top, suitable for the toughest climbs and
fast paths. Thanks to circle aluminium not afraid of bad weather
conditions, ensuring an excellent braking.
Cycloturist-GF: comfort is not the best value of these
wheels, but the low weight and performance expressed will be happy
cyclists most sports, with a good tube could be more like
gf more attentive to the comfort.
Positive aspects
Stiffness
Low weight
Fluency
