If you have a IG cassette, then yes, Shimano highly recommends you use the IG chain on your DT (for more acurate shifting)dlisabeth said:I need a new 8 speed IG chain for my bike. There seem to be quite a few different options (IG 31,50,70,90). What is the difference between all of these? I want to make sure I purchase the right one.
Thanks for the help
