Here is a great introduction and demo video of the Kurt Kinetic Road machine Indoor Trainer.  Enjoy…

This is a fluid trainer and also has resistance that varies with your cycling speed.  The trainer also has a slightly larger than normal flywheel which means that coasting lasts a little longer than trainers with smaller flywheels.  Fluid trainers replicate closely real road cycling conditions but are often plagued by leaking fluid chambers.  The Kurt Kinetic Road Machine has a sealed fluid chamber that is guaranteed not to leak.
