Naxo, the Swiss manufacturer of touring ski bindings, has filed for insolvency. The company is a 100 percent subsidiary of Rottefella, the big Norwegian manufacturer of bindings for cross-country and telemark skiing. According to Rotefella, Naxo did not reach the necessary volume in the production of units to become profitable. Naxo was founded in 2001 by former managers of Fritschi, another Swiss producer of ski bindings, and was sold to the Norwegians, who purchased some 62 percent of its shares then and the rest later. The future of Naxo is uncertain. It is largely up to an Austrian investment group that has taken over gradually a major stake in Rottefella over the past few years from a Norwegian investment fund, Katalysator.
