recently got back into mountain biking and bought myself a 1999 orange gringo for very little money , just noticed on the front shimano mech part no fdmc 18 , unless i am running on the small front chainring i have alot of play in the front mech what seems to rattle, it still changes gear perfectly ok but something is amiss is it a simple fix or am i better of to replace , its running a 8 speed rear cassette and its a top pull front mech , other than that how do i know what size it is, as i have no way of measuring seat tube and can i fit a new 9 or 10 speed xt front mech to my 8 speed gear system
