2026 K2 Mindbender 89Ti - SkiEssentials Ski Test Review
SkiEssentials · 8 Aug 2025 · 170 cm tested
Reviewed as the 2026 model.
The reviewer presents the K2 Mindbender 89Ti for 2026, examining its Titanal Y-Beam layout, flex, and rocker profile. He notes that while it sits in the popular category of ~90mm metal-laminate all-mountain skis, it differentiates itself with a looser tail and enhanced freeride maneuverability. This design allows it to excel in moguls and tight trees while retaining solid high-speed stability and edge grip on groomed snow.

2025 K2 Mindbender 89 Ti - SkiEssentials.com Ski Test Review
SkiEssentials · 17 Sept 2024 · 182 cm tested
Reviewed as the 2025 model.
The K2 Mindbender 89Ti returns with unchanged construction and fresh graphics. It excels as an energized frontside carver with a tight turn radius and energetic tail finish. While capable of slipping into bumps or trees and pivoting off groomers, its stiff tail and punchy rebound make it best suited for advanced to expert skiers who can harness its power on firm snow.

2026 K2 Mindbender 90 C - SkiEssentials Ski Test Review
SkiEssentials · 8 Aug 2025 · 178 cm tested
Reviewed as the 2026 model.
The reviewer evaluates the K2 Mindbender 90 C, noting its carbon spectral braiding and poplar-free aspen core. It caters well to intermediates up through advanced skiers looking for an approachable, agile all-mountain ski. It initiates easily into turns and releases smoothly from tails, shining in bumps and trees within moderate radius arcs. However, it lacks high-end shovel stiffness and stability when driven at aggressive speeds in wide GS carves.

Reviewed as the 2025 model.
The presenter examines the K2 Mindbender 90C, highlighting its updated topsheet while maintaining the same versatile carbon braid construction. It features an aspen micro block core, semi-cap build, and generous tip and tail rocker with traditional camber underfoot. Aimed at intermediate to advanced skiers, it serves as a lightweight, nimble all-mountain ski that handles variable snow, bumps, and trees easily, providing dependable edge hold without being overly demanding.
