Polyurethane (or PU) is an elastomeric polymer material known for its energy absorption, durability, and elasticity. It is commonly used in skateboard wheels and racecar bushings to make for a smoother ride.
NO MORE CHATTER An inherent problem with carbon and ultralight touring skis is chatter, due to the light and stiff materials used. PU sidewalls counteract this chatter by absorbing that extra energy and creating a more damp ride overall.
DURABILITY & VERSATILITY The elasticity of PU increases durability by 30% improving protection from sidewall impact when compared to ABS. Using PU in ski construction also allows for a permanent bond to the wood core and a seamless sidewall.
