Identical in shape to the 75 IS, the RTM 75 offers a still more forgiving and economical performance, with a core construction reinforced by just one wood stringer instead of two. It comes with the same binding, a 10-DIN Marker 4Motion, and features the same Progressive Technology, in which the tail is made thinner and more flexible for gentle, easily-skidded turn finishes. It's part of the seven-model RTM ("Ride the Mountain") series of frontside, all-conditions skis - the all-mountain heart of the Volkl collection. Waist widths range from 84 mm down to 73 mm, with performance and price decreasing along with width. Higher end models (the 84, 81, 80 and 77) are subtly rockered from tip to tail for soft snow performance. Lower end models (75 IS, 75, and 73) get tip and tail rocker for easy pivoting and skidding and are generally more forgiving and groomer oriented. The RTM collection features Volkl's XTD constructions, which are built with extra mass stacked over the edges for extra stability and edge bite. In lower end RTM models, these XTD rails decrease in size and mass to give those skis more forgiving performance. All but the value-priced RTM 73 have wood cores. All are sold with bindings.
