The Kastle TX87 Up is a tour freeride ski designed for experienced skiers who want a lightweight setup for backcountry exploration. With a 87 mm waist, it sits in the 90–100 mm range of tour freeride skis, offering a blend of stability on descents and manageable performance on ascents. Its flat binding plate provides flexibility to pair with a binding of your choice, tailoring the setup to your preferred touring style.
At 1,445 g per ski (174 cm), the TX87 Up falls into the very light category for freeride skis, making each uphill step noticeably easier and reducing fatigue over long approaches. The 124/87/111 mm dimensions give a subtle rocker profile in the tip and tail, enhancing float in soft snow and smooth turn initiation without sacrificing edge hold on harder surfaces. This combination makes the TX87 Up versatile for varied snow conditions encountered in tour skiing.
The 15.5 m turning radius at 174 cm strikes a balance between stability at speed and nimble maneuvering through tight couloirs or tree runs. The taillering numbers—124 mm tip, 87 mm waist, 111 mm tail—define the ski’s sidecut, which influences how it grips and releases through each turn. A flat binding interface means the skis arrive ready for direct mounting, giving you full control over your binding choice and stance setup.
