Light and agile, the Atomic RT 86 telemark/randonee skis grip impressively in icy conditions and have fantastic flotation in powder! Borrowing technology from Atomic alpine skis, the RT 86 features the Torsion Flex Control (TFC) system that utilizes a series of cutaways in the core and topsheet. TFC cutaways in the fore and aft of the ski create a smooth flex for optimal skiing performance. Nano reinforcement is integrated between the TFC sectors to provide exceptional torsional rigidity without adding cumbersome weight. Densolite core is lighter and more lively than wood, reducing swing weight for easy handling. Beta 4 profile ensures maximum torsional rigidity, uncanny edge grip and controlled tip-to-tail flex. Excellent response and turnability help you make short-radius turns down the fall line. Magnesium cap construction offers nice torsional rigidity while still providing a very even and smooth longitudinal flex.
