Excellent chain. IG (Interactive Glide) is an extension of Hyperglide, in which both sides of the sprockets are contoured to improve upshifting. I.G. sprockets are very slightly thicker than Hyperglide ones, and some Shimano Hyperglide chains may hang up if used on an I.G. cassette. The slightly wider I.G. chains work on either type, as do SRAM chains.Shimano's IG90 (same chain but prettier) 7 and 8-speed cassettes on both road and MTB bikes.

definitely a durable use chain.

Good chain. Never had a problem with these chains.
