Designed for competitors, the SPX 12 Rockerace is a binding based on the World Cup models. Offering excellent retention thanks to a very long elastic stroke, it instantly ensures the transfer of forces, better shock absorption and maximum limitation of untimely triggering. Its short mounting area and semi-suspended tail improve the flex of the ski for even more precision and control. It is only compatible with skis equipped with an R22 plate and ski boots that comply with the ISO 5355 A standard.
