The Slamm 100mm Ny-Core Wheels are high-performance scooter wheels featuring a durable 100mm nylon core and an 88a super high rebound (SHR) polyurethane (PU) rubber compound for superior grip and control. These wheels are often pre-fitted with ABEC-7 or ABEC-9 Chrome bearings, allowing for immediate use upon installation. With a 12-spoke core design and a flat profile, they are built to withstand rigorous use and are suitable for replacing worn-down or flattened scooter wheels. They are available in a variety of colors, including blue, and are sold individually or in sets.
