SFK wheel bearings will fit FF Rollerskis as well as other popular brands (SweNor, IDT, Swix, Fischer, and others).
We recommend that you change the bearings when you notice excessive noise when spinning the wheels.
When you purchase new wheel bearings, we can change the bearings for you free of charge. You pay for the bearings and shipping.
SFK started with one bearing design, and today is a world leader in design and production of both ball and pin bearings.
We only use, and have ever only used, SFK bearings in our rollerski wheels.
Note: The price listed is per unit (1 bearing). You will need 2 bearings per wheel.
