2025 K2 Mindbender 89TI

The 2025 K2 Mindbender 89 Ti gets a new graphic for this year but otherwise returns unchanged. This has been one of those skis that satisfies the needs of carving enthusiasts and all-mountain adventurers at the same time. We’ve remarked at how well these skis initiate with power and complete with energy, and that carries through to this ski. K2 has a long-standing tradition of building skis that excel in fun and creativity. The 89 Ti represents the true and pure all-mountain embodiment of that philosophy. This is a great zone to be in if you spend most of your time on-trail and in a carved turn, but it’s also useful and fun when you get adventurous and are looking for some softer snow and more creative skiing.

K2 keeps it simple in the wood core, relying on aspen stringers to boost the blend of light weight and high energy. With a good mix of attributes, this is a great way to keep skiers engaged and energized in any type of turn or terrain. On top of the core, K2 uses their titanal Y-Beam to solidify the performance. By placing more emphasis on the outside of the forebody and the center of the tail, K2 makes this ski feel incredibly damp, powerful, and grippy on firm snow with high energy rebound out of the tail. With solid edge hold underfoot where the metal is full width, these skis have a unique feel that is ready to tackle the firm snow on the mountain. Tester Spencer Brown notes that “This is a killer groomer ski that can seamlessly pop in the woods or bumps without giving up any performance. It has plenty of power and a very damp feel at higher speeds. The ski's shape allows you to pivot and smear the ski effortlessly.” The power and dampness stand out here, as the skis can hold up to aggressive and strong skiing.

At 89 mm underfoot, these skis feel like they want to be more involved in the groomer section of the mountain. This does not mean that bumps and trees are out of play, rather, the preference seems to lie on the smooth snow. Tester Dave Raybould notes that this ski does great in “most all-mountain conditions except for the extremes of firm snow or 6"+ deep powder. It's a good all-around all-mountain ski that does most things well with relative ease! You don't need to think too much about what you're doing, it's easy to recover if you make a little mistake.” The shorter radius makes it feel more engaging, like you’re part of the process as opposed to an unwilling participant. While the turn radius is shorter than most at this width, the ski does have an easy time going straight as well. The short turning nature, though, should not be overlooked.

While intermediates looking for their first metal ski will be fine here, the advanced and expert realm will take more advantage. These skis can hold up to very aggressive and strong skiing, so those that have good skills and strength will be able to push it to its limits. Even though it’s squarely in the all-mountain category as far as application and intended use, we find the Mindbender 89 Ti to be particularly useful and supportive in a groomer fashion. Wherever you choose to take this ski, expect direct initiation, energetic rebound, and an overall good time.
