Kurt Kinetic Rock and Roll Trainer
After one look at the Rock N Roll it is easy to see why it's one of the best cycle trainers in the world. It offers great stability with solid steel tubing and not slip rubber feet, yet allows you to rock back and forth just like you would on your bike. It relies on fluid resistance which is not only smooth and nearly silent, but also offers an infinite amount of resistance. Fluid resistance is actually fairly simple, it involves the use of a viscous liquid like an oil and a flywheel. The harder you pedal the more resistance the fluid puts on the flywheel which means that resistance is infinite depending on you.
Kinetic has their own app which works with the Rock N Roll in order for users to keep track of their metrics and compare them to their outdoor ride. The units setup is super simple and users can go from box to using it in about five minutes. All you do is add the extension legs, dropping your wheel in, and tightening the skewer system. All of this is backed by an unconditional lifetime warranty which make Kurt Kinetic that much more special among bike trainers.
