The Prolink Court Case

Yesterday was the expiring date for Rottefella AS to pay Amer Sports’ costs for the court case against Amer Sports regarding the Prolink binding system. That is what happens when you sue someone and lose in court. Amer Sports with its companies Salomon and Atomic were found not guilty on all five charges brought by Rottefella.

None of the charges were about the binding technology itself, because that technology is now in the public domain and free for anyone to use. What Rottefella charged Amer Sports with were instead the alleged violation of two Norwegian patents regarding a ski boot sole construction, one protected ski boot sole design, a marketing law and the illegal use of the protected trademark NNN. The patents were found invalid by the court and regarding the other charges the court could not see any violations.

The verdict was almost like a disaster for Rottefella. Not only does it have to pay circa 2 million NOK to Amer Sports and probably at least 1 million NOK to its own laywers, but it got two patents declared invalid and attracted considerable badwill for the whole action. Why didn’t Rottefella instead welcome Amer Sports, Salomon and Atomic to NNN and use the step of its competitors to further expand the use of NNN and NIS?

Prolink Is Legal

Yesterday I was informed by Amer Sports, the owner of Salomon and Atomic, that the Prolink cross-country binding system was found legal in the trial held in Norway where Rottefella had sued Amer Sports for having broken the law with Salomon’s new binding system that is compatible with Rottefella’s binding system NNN. I will get back with further information if I get to read the court decision.

Rottefella Adjusts — but Only Some Things

Norwegian World Cup dominant binding producer Rottefella has adjusted the mounting template for its screw mounted bindings by moving the pin line 2 mm forward. This is for compensating the slight tail-heavyness that results from the circumstance that the binding adds more weight behind pin lineĀ  (and balance point) than in front of it. However, Rottefella chooses not to adjust the mounting recommendations for Excelerator NIS plates despite the fact that those move the balance point further backwards than the screw mounted bindings do.

I am developing a universal mounting template that will take these balance point shifts into consideration. More about that later.

Salomon Prolink

Not surprisingly, the new binding Salomon Prolink has already become a favorite with some retailers. Oslo Sportslager in the Norwegian capital has decided to recommend for roller skis Salomon bindings only this season. This is because they want to go for a thoroughly screw attached binding after the reported problems with NIS bindings accidentally sliding off the mounting plates. Rottefella recommends and provides a special safety kit with a drill, mounting templates and screws for attaching a safety screw under the flexor of the binding that goes through both the NIS plate and the top surface of the roller ski shaft. Oslo Sportslager found it easier and better to use the directly mounted Salomon Prolink binding with its 5 screws per roller ski instead of the now 9 screws for NIS bindings and their separate mounting plates.

Ski-Roller 54

In the northernmost German state of Schleswig-Holstein there is an interesting website called Cross-Skating Schleswig-Holstein. At http://www.cross-skating-schleswig-holstein.de/doku.php?id=cross-skating-wiki:erfahrungsberichte:roesch_roller_1956 a very interesting article about roller ski history in general and the first serially produced roller ski, the Ski-Roller 54, in particular is accessible. Andrea Kittler of Cross-Skating Schleswig-Holstein visited the very knowledgeable roller skier Klaus Fink for a look back into roller ski history. The article is written in German.

Tail-Heavy Roller Skis

As one of very few among roller ski manufacturers in the world, Peter Breu, director at Woodski, has published his thoughts on the issue of tail-heavy roller skis: http://www.woodrollerski.com/heel-drop-what-it-is-why-it-matters-and-what-we-do-about-it/
