The Kinetic Road Machine is tops when it comes to fluid trainers. Silent and smooth, it allows you to log everything from fast intervals to threshold work to long, slow rides. To get fully outfitted, check out their list of accessories, in particular the Riser Ring and Pro Flywheel. For the full package, also consider purchasing Kinetic's new inRide power meter, which allows you to wirelessly pair a variety of Apple devices with a heart rate monitor and power sensor pod to measure power with your Road Machine.
