HIGH-QUALITY: The bike handlebar grips are made of EVA and aluminum alloy, which are durable, non-slip, soft, and comfortable. The ergonomic design provides a secure grip, ensuring comfort for both adults and children during rides. INTERNAL DIMENSIONS: The bicycle grips are designed to fit handlebars with a diameter of 0.87 inches (22.2 mm), compatible with over 90% of kids' bikes and widely used on mountain bikes, beach cruisers, scooters, folding bikes, downhill vehicles, 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 stability even on rough terrain, offering improved control. SHOCK ABSORPTION: Extended rides can cause hand and forearm fatigue. These grips help absorb shock while riding on trails. Combined with high-quality EVA material, they enhance 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.
