What is a Hyper Glide chain?
There are two types of Shimano chains
IG chain = has additional side plate shaping that optimizes upshifting and downshifting under load
HG chain= only has side plate shaping that will optimize shifting from smaller to larger gears
Is it a normal type chain?
Your chainrings/cassette will dictate which chain to use
If you have a HG DT = you can use a HG or IG chain
If you have a IG DT = for the best shifting you should use only an IG chain
Could I use a tool that works with a hyper glide chain on regular chains?
Yes
