Kästle RX11 SL TRI
The Kästle RX11 SL TRI is a performance-focused slalom ski for athletic skiers who enjoy short radii, rapid edge changes and precise turns on groomed slopes. Its compact, dynamic setup delivers explosive short turns, direct edge grip and an exceptionally agile feel.
The Twin Core made from poplar and beech is reinforced with Double Titanal, creating excellent stability, powerful rebound and a clearly defined race character. HOLLOWTECH Race reduces swing weight and supports fast, precise turn initiation.
The Full Race Sidewall and Armoclad Race Sidewall transfer power efficiently to the edge, while Fast Grip at the tip and tail ensures dependable hold from turn entry to exit. An Armoclad topsheet and metal tip protector complete the durable, premium construction.
