cassette, because the number of teeth on the neighbouring sprocket requires a different ramp pattern for an optimal shift. As a result, cassettes are sold as a cohesive unit—rather than as individual sprockets—with all the sprockets on a given cassette designed to work with each other. However, some mixing and matching is possible for a custom gear range, as long as all the sprockets' ramps are compatible.

The 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

hang up if used on an interactive glide cassette. The slightly wider 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.

The individual sprockets on a
Hyperglide cassette or freewheel are designed specifically to work with their neighbours. For example, the 18-tooth sprocket on a wide-range cassette (such as one for a mountain bike) will have a different ramp pattern than the 18-tooth sprocket on a narrow-range
