Engineering:Interactive Glide

In cycling, an interactive glide gear system is an extension of hyperglide, in which both sides of the bicycle gear sprockets are physically contoured to improve upshifting.

Interactive glide sprockets are slightly thicker than hyperglide variants, and due to this difference, some Shimano Hyperglide chains may hang up if used on an interactive glide cassette. The slightly wider (wider internal width) interactive glide chains work on either type, as do SRAM chains . The IG chains are wider internally but narrower externally than the standard HG chains that Shimano made at the same time; the plates of the chains are thinner.
