This is the racer’s choice binding! This lightweight Rottefella Xcelerator Skate 2.0 binding is lighter, more durable, and a more secure fit than the Rottefella Performance Skate. Fits all NNN-compatible boots (including Prolink and Turnamic). These bindings only affix to skis with a NIS plate (Nordic Integrated System, not included). Bindings are able to be fine-tuned by adjusting the binding (w/ a simple key included) forward for more control, or backward for more glide. Dual flexor system provides amazing control and balance of ski tip. Wide platform for stability and control. 188g per pair. Sold as a pair.
