Marwe wheels are known for their awesome durability, but even so, they will wear out if you use them enough.
Because the wheels decrease in diameter during their term, we recommend to change all 4 wheels.
The set includes 2 wheels optionally including mounted bearings and axle sleeves. For a complete set (4 wheels) you have to order 2 sets.
The wheels fit on the roller ski models Marwe 620XC and 610A. For the older models 610CAP and 610, please be sure to order the 105mm wheels, as these wheels also have a wider axle mount.
