How fluid resistance works
In a fluid trainer, resistance is created by turning a blade inside a container of fluid. This resistance is progressive, it increases as wheel speed increases.
Kinetic fluid trainers provide the most realistic replication of the resistance a rider experiences outdoors. It’s simple with fluid: Want to warm up? Put it in an easy gear and spin. Ready to work hard? Simply pedal harder and resistance increases. Doing an interval workout? Change gears and pick up the tempo—resistance meets you exactly like on the road. There’s no need to turn a dial on the trainer to go harder.
Kinetic fluid trainers, when combined with the inRide Watt Meter, allow accurate and consistent measurement of power based on the RPMs of the resistance unit for much less than any other power training solution.
Kinetic trainers are precisely calibrated and tuned to provide the exact same amount of resistance every workout, from start to finish. Kinetic uses a thermodynamically neutral medical grade silicone fluid in our trainers because it provides consistent, repeatable workloads and is not affected by temperature.
Kinetic fluid trainers feature an engineering breakthrough - our patented magnetic drive system for a lifetime of leak-proof performance. With other fluid trainers, the drive shaft enters the fluid chamber. This spinning drive shaft is the weak point of the unit. Our magnetic drive system uses two sets of powerful magnets on either side of a separating wall, so there are no moving parts entering the fluid chamber.
Rather than using an external fan to manage heat Kinetic uses an internal fan and 80 cooling fins, which provides both the quietest fluid trainer we have tested and the lowest operating temperature of any fluid trainer.
The flywheel on a trainer simulates the momentum of the bike and rider, increasing the effort needed to accelerate and maintaining speed when coasting. Kinetic fluid trainers have a heavyweight 6.25 pound flywheel for a more realistic ride.
