I am fortunate to have a separate dedicated indoor trainer, which I bought about 30 years ago. It's called the Houdaille Road Machine, and it simulates both wind resistance with speed and inertial resistance from acceleration with a vaned flywheel. They don't make them anymore, but something similar is being marketted as the Lemond Revolution trainer >>> http://www.lemondfitness.com/product...FRJY2godcVjyJQ
