The revolutionary thing about LeMond's Revolution Bike Trainer is that unlike most other types, it doesn't require you to rest your bicycle's rear tire on a roller for resistance. Instead you simply remove your rear wheel and put the trainer in its place. This has many important advantages, including a no-slip direct drive; zero rear wheel, rear tire or cassette wear; no need to carry a special trainer wheel to avoid wear and tear or flatting on your race wheel; and you don't need a trainer tire or a front wheel block either. Plus, it works with road, mountain and cross bikes. Equally impressive, the Revolution's progressive wind resistance simulates the effort of outdoor riding to optimize your workouts, and there's a weighted flywheel that replicates the momentum of a rolling bicycle, for smooth, natural pedaling, coasting and shifting. You'll also love the super-stable three-leg base with leveling feet that even lets you stand and sprint.
