This trainer really feels like riding outside, with an innovative side-to-side "Rock and Roll" motion. I've owned many trainers in the past, and this is by far the most realistic & smoothest. The additional pro-flywheel makes a big difference in giving more of a "road feel", and the turntable riser ring allows the handlebars to move freely My needs for training have gone away now, so I'm just not using it anymore Includes * Kurt Kinetic Rock and Roll Trainer in great condition * Additional 12-pound Pro Flywheel - $140 value by itself! * Kinetic turntable riser ring with 4 height settings - features a swiveling base that allows the front wheel to move freely and helps a rider perfect their technique * Quick release & 12mm x 140mm Thru-Axle adaptors
