The classic backcountry model with only a slight sidecut. easy climbs, but robust in difficult terrain. thanks to twincap construction and steel edges. Densolite Core: A combination of prefabricated densolite cores and high-tech fibres for ideal flex, glide and durability. Three variations depending on the ski model: -ultra high densolite -high densolite -densolite APG - Atomic Power Grip: Traditionally, if a waxless pattern has too many cutting edges per square cm, it is too dense and provides poor glide. If a pattern has too few cutting edges per square cm, it has fast glide, but poor grip. Atomic's new APG has a dense pattern with triangular gliding surfaces between the cutting edges. The end result is the sure and easy grip that comes with a dense pattern while maintaining a fast glide to make skiing easy and fun for all levels. -reliable grip even on steep terrain -exellent gliding properties The nowax zone is positioned according to defined parameters for target group, ski flex and ski length. The use of computer stiffness control guarantees every cross-country athlete optimal climbing and gliding properties if they choose the right ski. Sidecut (mm): 59/50/55 - atomicski.com
