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 depending on type of wheel configuration. For a complete set (4 wheels) you have to order 2 sets. In US6 the wheels are not available anymore so we recommend a combination of US0 in front and US7 as rear wheel.
These 105mm wheels fit only on the older 610CAP and 610 roller ski models, please be sure to order for 620XC and 610A the 100mm wheels.
