K2 Disruption STI — topsheet
The read

A piste-focused carver rated for advanced to expert skiers, this ski sits near the narrower end of its category cohort and pairs a short-radius shape with two sheets of titanal for precise, damp edge hold on firm groomed snow. The Speed Rocker tip aids turn initiation without sacrificing the underfoot camber grip that drives its aggressive arc. It rewards skiers who pressure their edges hard and seek locked-in control at speed on hardpack.

Specs & what they mean

What the Disruption STI's numbers add up to, as a model — the three things that define how it skis.

Turn & shape

A 13.6-meter radius covers versatile, all-purpose turn shapes; a generous tip taper keeps turn entry easy and the shovel quick to engage.

Stability & dampness

A full titanal layup gives it a damp, planted build that holds a line through rough snow and rewards a forward, driving stance. At 1,630 g the damping comes without a heavy overall weight.

Float & width

At 72 mm it's a narrow, firm-snow ski — quick from edge to edge and built to grip hardpack rather than float. A cambered profile keeps it locked to the snow for grip rather than smear-and-release.
