I got a Cult Match Freecoaster from a friend. When I held it in my hand it seemed to work just fine. I laced it up with a new rim and spokes then put it on my bike. Now when I put my foot down to go it has 3 full cranks of slack, sometimes more, sometimes its a quarter crank. If I stop pedaling, then right away go to pedal, its a quarter crank. But if I just ride around, going down hill, moving my cranks involuntary, when i go to pedal uphill, its around 3 full cranks then it engages. I was told to buy a ball and spring kit but I thought id see what other people think. Hopefully there is a simple solution!
