Bicycle shops, Where? Tiendas de Bicicletas, Donde?

This summer I am going to cycle the Camino Norte from Santander.  If I have a bike problem and need parts or repairs where can I find bike shops?
The internet shows several bike shops at Santander, Oviedo, Lugo, and Santiago, but are there bike shops in smaller towns/villages.  For example at: San Vicente de la Barquera, Luarca, Ribedeo, Mondonedo, etc.
