Was helping a buddy change his front sprocket today and noticed that his front sprocket had play, not rotational play but more so a loose/wiggle type of play. I had him leave the bike so I could look at it a bit more as it could be that the nut has come loose (although it doesn't look like it but I will confirm tomorrow). Anyway, do these bikes have some play in them at the front sprocket? If not, other than the possibility of a loose nut, what could be the problem/fix?? TY!
