The XBi TC bindings help to give you control over your movements. Like this entire line of racing skis, the Dobermann GS Pro is designed with an eye-grabbing multicolored graphic. This ski differs from the lower cost Dobermann Spitfire Pro EDT in that it has a 67mm. waist (as opposed to the Dobermann Spitfire Pro EDT's 72mm. waist), which encourages ultra-fast speeds. This ski differs from the identically priced Dobermann SL Pro in that it has larger sizes (171cm.-186cm. range as opposed to the Dobermann SL Pro's 155cm.-170cm. range), as well as a different sidecut (111-67-97 as opposed to the Dobermann SL Pro's 120-67-103). There are size options available for the Nordica Dobermann GS Pro race ski.
