hi, i got a shimano mf tz500 and i have a problem with the lockring or how tf is this thing called (i actually cant put a photo bcs i dont have 10 posts but its that thing with 2 holes and need a pin spanner to remove it or a hammer
and u rotate clockwise to loose it and under it there are bearings). My problem is that it is loosening after 5-10 minutes of pedaling harder and the freewheel has play which cant be solved because i tried to tight the lockring at maximum and it still has play, and the play is annoying bcs i can hear a knock when im on the third sprocket or lower. Today I tried to remove 1 ball and see if its still loosening but i still have that play, i tried to remove or put some spacers from some old freewheel and i still have the same play, i also tried with another lockring. How can I fix the both problems???? The bike is 1 month old...
sorry for my bad english
