It attaches quickly and easily to your Road Machine or Rock and Roll flywheel (sold separately) for a total of 18 pounds. It takes your Kurt Kinetic trainer's already stellar real-road feel and ups the realism, which is a must for hard-core endurance workouts, like tempo and long distance rides. You'll also experience longer wind-ups when doing sprint intervals and a longer coast-downs.
