- Material and build: Made from resilient polyurethane (PU) polymer, these roller skate wheels combine high wear resistance with good elasticity to deliver a smooth, consistent ride across different surfaces. - Bearings and performance: Fitted with carbon steel ball bearings for long service life and reliable, stable performance. Bearings enable higher speeds while keeping rolling noise to a minimum. - Shock absorption and comfort: The high-elasticity PU dampens impacts and reduces vibration, making skating more comfortable on uneven terrain such as asphalt roads and park paths. - Hardness options for different uses: Available in four durometers — 82A, 90A, 92A, and 95A — so you can choose the right balance of grip and roll resistance for your environment. Lower numbers provide more grip and cushioning; higher numbers deliver faster roll and longer wear. - Key benefits — why you need these wheels: - More comfortable rides on rough or mixed surfaces due to superior shock absorption - Longer-lasting performance because of wear-resistant PU and durable carbon steel bearings - Quieter, faster rolling for both recreational and fitness skating sessions - Flexibility to match riding style and surface with multiple hardness choices Typical applications - Urban commuting: Confidently roll over asphalt streets and cracked sidewalks with improved shock absorption and durability. - Park and leisure skating: Enjoy smoother turns and quieter rides on mixed pavement and paved paths. - Indoor/outdoor recreational use: Choose the appropriate hardness for rink sessions (firmer wheels) or outdoor cruising (softer wheels). What to expect - Durable PU material that resists abrasion and maintains elasticity - Stable, long-lasting carbon steel bearings for consistent speed and low noise - Multiple hardness options (82A/90A/92A/95A) to suit different skating environments Note: Product specifications focus on material (PU), bearing type (carbon steel), shock absorption, and available hardness options. Select the hardness that best matches your typical surfaces and riding goals.
