The "XC-R," a carving-specific board designed for both ease of handling and speed, adopts a full hammerhead shape. The "R" represents "Revised," "Realize," "Revolution," and "Radius." The "XC-R" is a carving-specific board with a full hammerhead shape, derived from the freestyle race carving model "XC," but with a focus on ease of use. By deepening the side curve and making subtle adjustments to the overall flex balance of the board, it sacrifices some high-speed stability compared to the "XC," but significantly improves turning ability and handling. Furthermore, it caters to users who want to emphasize the feeling of riding on the edge, with the base finish set to semi-flat (flatter than before), allowing for automatic carving simply by edging. The "XC-R" will bring new "realizations" and a "revolution" to your carving life, such as "I want to aim for the ultimate alpine-like carving with soft boots!" ※ By adding the three sizes of "XC-R" (154/157/160) to the two sizes of "XC" (158/162), the size variations have increased, allowing you to choose your preferred size. XC-R TECHNOLOGIES Core Material: OGK2 Core Reinforcement: Glass Fiber + Carbon Sheet Wide + Asner Sheet Top Sheet: PE (Black) PC Plate: Type-s Edge: Stainless Sole: Sintered Graphite Sole Finish: Stone Finish [semi-flat] I have used this board for about 3 hours a day, rotating it with several other boards. I have applied a deck protector sheet, so there shouldn't be any binding marks. Also, I haven't modified the edges. The waist size is 260, so there will be no boot drag even with 27.5 cm boots. This is a used item, so please consider purchasing only if you understand this.
