Safety instructions

  • Dimensions stainless steel spikes:
    Outer diameter: 216mm
    Inner diameter: 165mm

    Thickness: 1.5mm
  • Make sure that all screws are tightened and the stainless steel spikes are firmly attached to the wheel.
  • The material of the holder (PLA plastic) is conditionally heat resistant. (45-55°C)
  • PLA is a UV resistant material. (Holder)
  • The surface of the black plastic holders may wear over time and show appearances of wear. This is normal and only occurs more initially, but does not affect the performance of the product.
  • The spikes and screws are made of stainless steel (V2A) and are therefore resistant to corrosion and weathering.
Material notes

Stainless steel (V2A) is a corrosion-resistant and weatherproof material. Nevertheless, corrosion (rust) can occur with the contact of, for example, metal chips.

Holder (plastic):
The adapter is made of high-quality polylactide (PLA) plastic. PLA is both a colorfast and UV-resistant material and has low flammability. Polylactide has a temperature resistance (glass transition temperature) of approx. 45°C-55°C and is therefore not suitable for use in the vicinity of direct / extreme heat and heat sources.

We wish you a lot of fun with your product.
