Find some alone time.
If we all had our druthers, we’d own multiple trainers — a
lightweight one for travel, one that feels as smooth as the road for
home use, and maybe a set of rollers, too. With the Kinetic Road Machine
Fluid Trainer, you get the same smooth fluid resistance unit as
featured on the Rock and Roll Trainer attached to a lighter, more
compact frame. It’s the best of both worlds.
The Road Resistance Unit is an impressive feat of engineering. It
uses a 6.25-pound (2.84kg) flywheel and a completely sealed fluid
resistance unit. Together, they give you a consistent road-like feel and
resistance curve. The tire roller is made of stainless steel and is
2.5in (6.35cm) in diameter, which is a good bit larger than much of the
competition. The larger roller means less wear on your tire and it
reduces the temperature of the spinning elements.
The resistance unit is unique as it's made of two parts. The first is
the driver made of a small flywheel embedded with six rare-earth
magnets. The other half is a completely sealed cast-aluminum fluid
chamber that is bolted to the housing containing the driver. The fluid
chamber contains an impeller with corresponding magnets. As you ride,
the magnets in the driver spin the impeller through medical-grade
silicone fluid to provide the resistance. And since there is no
driveshaft entering the fluid chamber, the Kinetic design eliminates a
common design weakness of most fluid-resistance units.
As expected, the system builds heat in the form of friction. However,
the fluid acts as a coolant and the chamber has 80 cooling fins on the
outside that act like radiator fins. It's impossible to overheat the
chamber or reach a point where performance is diminished. The silicone
fluid retains its physical properties, even up to the normal operating
temperature of 325degrees Fahrenheit when riding 25mph.
There are several benefits to this system. Because it doesn't
overheat, the viscosity of the fluid doesn't change, and that results in
a consistent road-like power curve that increases as your speed
increases. Kinetic published a chart to show exactly what speed goes
with how many watts. To give you an example, it takes 143w to ride at
15mph, 258w at 20mph, and 25mph will take 430 watts.
For the Road Machine Fluid Trainer, the Road Resistance Unit is
attached to a more traditional triangular base. The base is 32in
(81.28cm) wide when open. The bike is attached to the trainer via two
threaded knobs, with a locking quick release on the right side. When
folded flat it is 26in (66.04cm) wide and 6in (15.24cm) tall, a good bit
smaller than the packed size of the Rock and Roll Trainer, and it
weighs about 20lbs less. It works with wheels from 22in to 29in in
The Kinetic Road Machine 2.0 Fluid Trainer is green and comes with
its own quick release skewer that assures a good fit in the cone-shaped
cups that secure your bike to the trainer. Like all Kinetic trainers, it
comes with an unconditional lifetime warranty. A bike computer, that
shows power as you're riding the unit, is sold separately.
