OGSO Ryumon — Review

The OGSO Ryumon is the Chamonix boutique's 96-98 mm all-mountain freestyle ski from their Scurry Odyssey Series. Verified sidecut per length: 132-96-120 mm at 162 cm (15 m radius, 1650 g), 134-97-122 mm at 172 cm (16 m, 1750 g), 136-98-124 mm at 182 cm (17 m, 1850 g). Available lengths 162, 172 and 182 cm. Manufactured at Kästle CZ.

At 96-98 mm underfoot with a 15-17 m radius, the Ryumon is a versatile all-mountain shape with freestyle-adjacent playfulness. Weights of 1650-1850 g are moderate for the segment. It handles piste with a snappy medium-radius carve, floats through soft snow off piste, and delivers a playful character in trees and terrain features. The 5 mm underfoot camber balances edge grip with pop.

Core: wood core with reinforcements typical of OGSO's Scurry Odyssey Series construction. Rocker profile with 5 mm underfoot camber, long tip (150 mm) and moderate tail (120 mm). Sidecut varies per length (see above), radii 15-17 m. Available lengths 162, 172 and 182 cm. Manufactured at Kästle CZ.

Compared to the Icelantic Pioneer 96 the Ryumon is similar in waist and playful character. Against the Head Kore 94 Ti it is heavier and less directional — the Kore is piste-driven, the Ryumon more playful. Compared to the Volkl Blaze 94 it targets a similar all-mountain segment with a boutique construction approach.

Pros

• Verified per-length data across all three lengths (dimensions, radius, weight).
• Versatile 96-98 mm waist handles both piste and off-piste.
• 15-17 m radius accessible for medium-radius carving.
• Boutique Chamonix design manufactured at Kästle CZ.

Cons

• Three lengths (162, 172, 182 cm) — no options for very small or very tall skiers.
• Premium boutique pricing versus mainstream 96 mm all-mountain skis.
• Weights (1650-1850 g) are moderate rather than exceptional for the segment.
• Not built for touring — resort-oriented weight and construction.

Verdict: A boutique Chamonix-designed 97 mm all-mountain freestyle ski for playful skiers who want versatility across piste, powder and trees. Best matched to a technical, playful style rather than piste charging.
