It decouples the cassette, chain and cranks from the driven rear wheel so that they do not continue to rotate when you roll without pedaling. The rear wheel is therefore able to overtake the stationary crank in terms of speed, which is why freewheels are also called 'overrunning clutches'.<\/p>\n\n\n\n<h3 id=\"c7f92de7-a376-4a34-b8b0-7192c6a927a8\" class=\"wp-block-heading\">Type<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"423637dd-0b5c-458d-b391-306ab448af64\">The Stromer freewheel is a pawl freewheel.
