I'm thinking about buying a secondhand Noordi Fjordi stroller, but we are looking for new wheels for it. It's almost impossible to find something online. Do you have any suggestions where to find spare parts?
It is very very hard to fins spare parts like that, especially for brands that are not the largest, global ones. I suggest reading and trying out stuff I recommend in this article about stroller replacement parts - especially contacting the manufacturer or a distributor around you, OR looking up stroller in classifieds that are in a bad shape, sold for parts. Good luck!
