Rubena are one of Europe€™s leading specialist producers of bicycle tyres and inner tubes. First known as Rubena in 1947 this company has a rich history and is based in the Czech Republic. All of Rubena's products are strictly quality controlled and they have a great range which means they can offer some of the more obscure bicycle and children's pram inner tubes and tyres which aren't always available from other producers such as bent/90 degree valve options. Thank you Rubena for solving quick a few problem for cyclists and parents!
