Kretlier 4.5 Flywheel
The Flywheel is a simple, heavy device to add rotating mass to your Kreitler Rollers. Running off a belt connected to the rear drum of your rollers, the Flywheel creates a more natural road-like feel to riding rollers.
Getting up to speed takes a little more effort, and momentary interruptions to your pedaling do not slow you down as much. There is also an increase in resistance associated with using the Flywheel, due to the belt friction. The Flywheel works with the Standard Frame only, not the Kompact Frame.
