In terms of wheels, the thick rubber wrap of the skates can be used to reduce the impact and improve the durability to a greater extent, and avoid the separation of the black wheel core and the transparent PU rubber. Lenva's new bearings use ultra-precision high-speed ball bearings to ensure product stability and durability.

Our wheel is made of thick transparent polyurethane material for better impact performance and more excellent durability, which could avoid the separation of the black wheel core and the outer transparent PU tread. Polyurethane wheel offers a quiet and smooth-rolling feature.

Double ball bearing of the wheel is ultra-precision high-speed ball bearings that could ensure caster's stability and durability.

Also, during the production process, our quality control is quite strict, and every product is subject to quality inspection. That's why our LENVA 3 inch black rollerblade caster wheels are the hot selling items on Amazon.
