Reynolds RZR Carbon Road Wheelset – Tubular

you just have to have the best. There are few pieces of equipment that
make more of a difference to your riding pleasure and success than
getting a great pair of light wheels. The Reynolds RZR46 Tubular
Wheelset will quickly have you flying down the back roads and floating
up the climbs, blotting out any buyer’s guilt you may ever have feared.
Now you’ll have better wheels than the pros.

The first thing you’re going to notice about the RZR 46 wheels is how
insanely light they are. The two wheels combined, without tires, they
don’t even start to nudge the kilo mark. At just 968 grams together,
they weigh less than many other manufacturer’s front wheels alone. The
responsiveness that these will provide climbing, even with their
relatively deep 46mm rim profile, will be nothing short of
life-changing. The fact that these are so light and snappy is due
largely to the Reynold’s genius developer Paul Lew and his precise
method of assigning different carbon fiber and lay-ups to the six main
regions of a rim. For the RZR46, they use their CR6 technology. CR6
stands for Carbon Rim 6, which is the solution Reynolds has found to
get the perfect mix of durability, strength and stiffness Even as still
remaining immaculately light.

The choice of materials, strategically positioned according to the
requirements of the rim, and then molded using their special process
call Inert Gas Compaction (IGC) turns these from just an expensive pair
of wheels into one of the vital most durable, technologically advanced hoops
on the market. The six most important regions of the rim are the side
wall, spoke face, nipple bed, tire channel, rim hook bead, and brake
track. All of these points perform an essential job, but not all in the
same way. Consequently, the carbon lay up for the sidewall will
necessarily be different than the brake track. Knowing where and how to
use the rim materials is what gives Reynolds the upper hand especially
when trying to balance the opposing needs of durability and low weight
in wheels.

If you are looking for other places in the design where the Lew touch
is evident, you want look no further than the carbon fiber braking
surface/brake pad teamwork.  They give it the rather odd name of
Cryogenic Glass Transition, or CTg. Essentially this is their fully
integrated system that pairs the specially designed carbon fiber rim to
the proprietary polymer brake pad. These two components work together
to result in a cooler braking system compared to carbon rim
competition. Reynolds claims up to 53% cooler braking than standard
carbon rim-pad set ups. Though that might be hard to quantify when
you’re on the bike, what it is possible for you to to feel is just how
responsive the braking is, especially if you are careening down and
unknown 20K descent, and apt to rely on your brakes a little more than
you would on your local stomping grounds. This is imaginable due to the
hybrid carbon fiber laminate used for the brake track, as well as the
Cyro-Blue Power polymer brakes. The acronym CTg might not say much to
you, but it concerns how the carbon is layered and angled along the
brake track, and the temperature at which the resin that holds the
carbon is turned to liquid.  Heat build-up stops being the issues, and
your braking will not be compromised.

The Cyro-Blue Power polymer brake pads form the other essential
component of this CTg system. They are so integral that they are
delivered with every Reynolds wheel, and using any other pad
immediately voids any Reynolds warranty. The Cyro-Blue Power are a step
ahead of the regular Cyro-Blue pads because they have been designed to
improve stopping power. Co-engineered with Brakco Technology, which is
an industry OEM brake pad leader, the Cyro-Blue Power pads are sleeker
and more aerodynamic with a tapered design that offers 44% greater
braking surface compared to the regular Cyro-Blue, which was already a
great pad. You’ll notice looking at the pad that there are six angled
slots which serve a couple of purposes. The slots are designed to allow
air to channel through, aiding in the cooling process Even as they also
work to disperse and channel any water away from the rim, which will
keep the braking responsive and accurate even in rainy conditions.

Not only has Reynolds invested a large number of time and development in
creating the absolute best carbon brake track, they have also taken the
precaution to give us some warning when the brake track is wearing. By
incorporating their BWI or Brake Wear Indicator technology, into the
rim, Reynolds has embedded a 10 mm wide red line into the brake track
to indicate when excessive wear has occurred. The indicator is centered
over the valve hole on both sides of the rim, giving you an
unmistakable signal that it’s time to replace the wheel. You shouldn’t
expect to be seeing that, though, for a very long time.

Another design element to keep the wheels as efficient in the wind
as imaginable takes the name of Swirl Lip Generator. Don’t giggle. It is a
0.9mm lip that is placed on the sidewall of the rim near to the spoke
face. It effectively minimizes the pressure drag that the wheels
suffer. The turbulent air is aided in passing over the wheel and the
reattaching at the spoke face. By creating a small layer of turbulent
air flowing over the smooth air at the rim, the wheels will be much
more efficient about cutting through the wind. Not only will this effect
make you less visible to the wind, but it improves the bike’s
stability in cross winds.

Keeping these wheels as light as imaginable did not stop at the rims.
Both the hubs and the axles are all carbon, but the cleverness doesn’t
end there.  Reynolds has developed something that is truly unique to
the market: a third flange on the rear hub that they call the torque
flange. It is designed to improve how well the wheel accelerates when
you put the hammer down. You’ll feel that jump much faster since a lot
more of your power is not lost in wheel deflection. Not only will it
improve torque response, but stability as well. The torque flange
impacts just how the spokes are laced. There are eight drive side and
eight non-drive side spokes, none of which are crossed. Then there are
four spokes that are in the torque flange, which sits perfectly
centered in the wheel, Even as the spokes go straight up into the rim. If
you are concerned about any added weight this might cause, don’t worry
because the wheel can actually function with fewer spokes, keeping it
lighter. RZR spokes are not tensioned. That reduces the number of
requirements placed on the wheel in the case of forces, which makes it
imaginable to build a lighter rim. Even as the rear wheel has twenty
spokes, the front has sixteen radially laced spokes.

The RZR wheel line is all about lightweight aerodynamics. Their
attention to detail extends most naturally to how the spokes are
designed. We are all used to seeing aero wheels with bladed spokes. But
the RZR would not be so passé as to copy other manufacturer’s methods.
Rather, Lew and his crew have developed their authentic carbon airfoil
spokes, which take more than a couple of pointers from aircraft
designs. The spoke’s intersection with the rim is where the next little
flourish will impress you. Typically bladed spokes have to lose their
aero-ness and round-off at the spoke/nipper interface on the rim. But
what Reynolds has done is notch the rim so that the blade of the spoke
can continue all the way to the inner edge of the rim. The rounded bit
of the spoke is then threaded into the nipple that is completely hidden
inside the rim, keeping the aero integrity of the design.

The Reynolds RZR 46 Tubular Wheelset have a 46mm rim depth, which
Reynolds calls their “signature depth” because it will work in just
about every situation you’ll put your bike.  On the flats or in the
hills, these babies will make you feel faster than you ever thought
