Description of Atomic Nomad Highnoon Skis w/ 4R 310 Bindings '09 In order to float harmoniously through powder, the ski needs a wide geometry- a geometry that would normally make the ski stiff and heavy. A problem Atomic solved using an ingenious system: Torsion Flex Control sectors, of TFC. By removing material where minimum power is required for a turn, TFC makes Nomad skis light and smooth withoug sacrificing edge grip or performance. Features: 121-72-106.5 R 17mm Beta TFC 4+2
