Kästle TX107 — Review

The TX107 is the widest entry in Kästle's touring line — 107 mm under foot, paulownia/poplar twin core wrapped in carbon-glassfiber, 1,450 g per ski at 171 cm. Where the TX99 keeps the standard Directional Touring Rocker, the TX107 swaps in a Double Rocker (progressive both ends) and a noticeably longer per-length radius that scales from 15.2 m at 171 cm to 19.2 m at 185 cm — engineered for big open powder lines, not tight-tree work.

On the way up, 1,450 g per ski at the short length is a real accomplishment for a 107 mm platform — the carbon-glassfiber wrap keeps the ski stiff enough that you don't lose energy to flex, and the Hook Free shovel and tail glide cleanly on skins. On the down the Double Rocker keeps the tip floating in soft snow even at moderate speeds, and the longer-length radius (18-19 m on the 179/185 cm) rewards big-mountain stance on open bowls. It will carve a piste back to the lift but the 1.3° base bevel and Hook Free tail mean it will skid out of corners rather than rail them. Tight trees will feel reluctant at the longer lengths.

Armoclad Sidewall construction (semi-cap sandwich) with Hollowtech Evo forebody. Ultra Light Twin Core (paulownia/poplar woodcore) wrapped in a Carbon & Glass Fiber winded core. Low camber profile with Double Rocker (progressive both ends); Hook Free shovel and tail. Factory bevels 88° side, 1° base. Lengths 171 / 179 / 185 cm. Per-length weight: 1,450 g (171) / 1,520 g (179) / 1,570 g (185). Per-length radius: 15.2 m (171) / 18.1 m (179) / 19.2 m (185).

Closest internal sibling is the narrower Kästle TX99 — same construction signature but with single-rocker tail and tighter radius, more all-rounder. For more weight and resort-down-stability, the freeride Kästle Transcend 104 is the step over to non-tour use (Powerzone Titanal instead of carbon-only). Cross-shop, the K2 Wayback 106 mens is the directly comparable American wide-tour rival; the Atomic Backland 109 is the Austrian alternative; the Movement Alp tracks 102 is the Swiss option at slightly narrower waist.

Pros

• 1,450 g per ski at 171 cm is light for a 107 mm tour platform.
• Double Rocker keeps the tip floating in soft snow at moderate speeds.
• Per-length radius (15.2-19.2 m) scales correctly for length-specific stance.
• Carbon-glassfiber wrap keeps respectable edge hold on the way back to the lift.
• Three-length range (171-185 cm) accommodates taller chargers.

Cons

• Longer lengths (18.1-19.2 m radius) reluctant in tight trees.
• 107 mm is overkill for hard-snow tour days.
• Hook Free both ends + 1° base bevel mean piste descent will skid not rail.
• Boutique pricing relative to mainstream wide-tour skis.
• Carbon-only construction chatters where heavier freeride skis hold.

Verdict: The right TX for tourers chasing big-mountain powder lines who prioritize float over uphill speed. Best matched to taller, experienced tourers in soft-snow objectives; mixed-day tourers will be happier on the TX99.
