One of the common complaints levelled against indoor trainers is a lack of real world road feel that can leave riders feeling off kilter when they remount their steed and hit the roads in the spring. Kinetic answers that complaint with the Kinetic Fluid Trainer Rock 'N Roll Smart with InRide Sensor, boasting a resistance unit and frame designed to mimic the natural movement of riding out on the road. This version adds inRide sensor technology, letting you smoothly crank out the miles with a plethora of data tracking and workout planning options. Kinetic's Road Resistance Unit is a revolutionary piece of engineering. The 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 a reduction in the temperature of the spinning elements. The right side has a 6. 25lb 2. 84kg flywheel, the heaviest around, and gives the satisfying feeling of momentum when you're spinning up to speed, holding speed, and slowing down. On the left side is a unique two part resistance unit, which is the heart of their system. Of course, this system builds heat as you ride your energy has to go somewhere in this case 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 325 degrees Fahrenheit when riding at 25mph, resulting in a consistent road like power curve that increases as your speed increases. To give you an example, it takes 143w to ride at 15mph, 258w at 20mph, and 25mph will take 430w. The Rock and Roll Trainer doesn't have the traditional dual triangle frame found on most stationary trainers because they want the bike to be free to sway and bob to more closely mimic how a bike behaves outdoors.
