HIGH-QUALITY: The bike handlebar grips are made of EVA and aluminum alloy, which are durable, non-slip, soft, and comfortable. The bicycle grips are ergonomic and provide a firm grip, ensuring comfort for both adults and children. INTERNAL DIMENSIONS: Bike grip length is suitable for over 90% of kids' bike handlebars with a diameter of 0.87 inches (22.2 mm). Widely compatible with mountain bikes, beach cruisers, scooters, folding bikes, downhill bikes, tricycles, and commuter bicycles. LOCK ON: The bike grips feature a double locking ring clamp design. The rings are secured using a 3mm hex key, tightly fastening the grips to the handlebar. This ensures the grips remain secure even on rough terrain, providing better control. SHOCK ABSORPTION: Extended rides can cause hand and forearm fatigue. These grips offer improved shock absorption, helping reduce strain while riding on trails. The high-quality EVA material enhances grip and handlebar control. INSTALLATION TIPS: Apply a small amount of soapy water, detergent solution, or car wax to the inside of the grips as a lubricant. This allows for easy and quick installation.
