Question for Ironman experts
My 89 Expert's Suntour GPX group was very noisy shifting when I first got it so I took the recommendation from a member here and switched the freewheel to a Sunrace R30 and the chain to a KMLC Z-72 and that made a world of difference .
I'm curious if there are any changes I can make to my 87 Expert's Shimano 105 group to get the same results?
