When we are peddling the bike, there is clunking sound coming

Customer Question

when we are peddling the bike, there is clunking sound coming from the drive train, you can feel it in the pedals, it feels as if the drive train has some play in it and as the crank comes around it seems to catch up with the drive train. At that point the clunk occurs, and you can feel a more solid connection with the drivetrain. you feel this clunk in your feet so it is definitely in either the crank or the drive train,It is all pretty subtle, but something is definitely wrong between in the drivetrain. In a brief moment it seems as if there isn't quite the resistance and then you catch up, but it happens so quick it is hard to tell what is going on,
