Our Verdict

A true "instructor ski," the Mindbender 90 Ti surprised our crew of testers with its solid overall performance. At only 90 millimeters underfoot, this ski is still able to float well through the powder. Lighter than others in our review, K2's Titanal Y-beam helps to keep weight down. As a result, the Mindbender provided us with good vibration dampening while also allowing for an easily controllable rebound. Geared towards carving and firmer snow, the Mindbender 90ti has more than enough oomph to chase the kids through the trees and all around the mountain.

Our Analysis and Test Results

K2's all-new Mindbender 90 Ti delivered our testers with a forgiving and stable skiing experience. We think this ski is accessible to a wide variety of skiing abilities thanks to its consistent and damp overall feel on piste. We also found the narrowest in the Mindbender lineup to be versatile and agile enough to deviate from the groomers into the bumps at will. Constructed with a mix of wood types and a Y-shaped titanal layer, this ski delivers a damp and easy turning experience.

Stability at Speed


The Mindbender 90 Ti is one of the narrowest skis in our lineup, and therefore we expected on-piste excellence from it, and we weren't disappointed. K2's construction blends a maple and aspen wood core with their titanal Y-beam. We experienced a damp and stable ride quality that was nearly as exciting as our highest scorers. We see this ski providing a solid platform, especially to those on their way to becoming more aggressive skiers.

Carving Ability


Carving performance from the Mindbender 90 Ti is confidence-inspiring but not as exciting as other models in our review. Our testers were pleased with this skis edge-to-edge quickness and overall grip. K2's beefy extended ABS sidewall seemed to keep the torsional rigidity of this ski well composed. The Mindbender 90 Ti is lighter than the highest-scoring models that have more pop. This translates to more forgiveness overall, especially when learning to carve at higher speeds. Our testers see this ski to be a strong contender in this category as a result.

Powder Performance


Frequently, bigger is better, especially on powder days. Sizing up, going wider, and leaning back are commonly overemphasized on deep snow days. While 90 millimeters underfoot wouldn't be our pick on truly bottomless days, some skiers enjoy being in the snow rather than on top of it. The K2 Mindbender 90Ti continues to provide its stable qualities through ankle-deep powder at the least and can help keep you honest as a result if you are trying to work on your technique. Simply put, this ski is a great option for days where "bottoming out" is likely.

Crud Performance


The Mindbender 90 Ti does fall short in this category compared to its other scores across the board. This is to be somewhat expected, especially for one of the narrowest skis in our lineup. When we toned the speed down and picked our way through slop and chop, this ski was able to manage. Part of the all-mountain ski search is knowing and respecting a ski's strengths and weaknesses. If you are looking to charge hard through every snow condition, we suggest a slightly burlier model.

Terrain Playfulness


The quickness and lightness of the Mindbender 90 Ti really pulled through for its playfulness score. With a strong preference for firmer snow and carving, this ski still proved to our testers that it could play. Bumps and rolling terrain were definitely the Mindbender 90 Ti's preference over jumps and slashing.

Value


The Mindbender 90Ti is priced to sell. K2 does a fantastic job in offering such a value-rich product, especially when compared price-wise to the rest of the skis in this review. If your skiing is mostly on-piste focused, we think this price to performance ratio is hard to beat.

Conclusion


At an affordable price, we see the K2 Mindbender 90 Ti as one of the best values in this review. This ski surely shines on-piste, yet also serves itself well in conditions that other skis are better suited for. For this reason, we see this ski as a true all-mountain ski despite its narrower waist. The overall ride quality is good and predictable, and we think this ski is well suited for the intermediate to advanced crowd actively working on their skiing technique.
