Item Description: These Grip Puppies will give more comfort to your ride and will reduce vibrations. They simply slip over your standard rubber grip (no need to remove standard grip) and leave you with a soft, squeezable, tactile grip that will give greater comfort to any bike. Moreover, vibrations are reduced through the grip. Hold very strong when fitted - a simple and very effective solution. Grip Puppies will fit all standard grip sizes. The standard Grip Puppy will fit standard bars sizes and grips. They are 5" (12.7cm) long and will fit grips that are 1.25 (3.17cm) to 1.45 (3.68cm) inches in diameter (remember: they fit OVER your standard grips, you don't need to remove them). Grip Puppies can be trimmed with a craft knife or similar if needed (using appropriate care!). They are great for adding a little extra thickness and comfort to your grips. They will also work with heated grips. INSTALLATION INSTRUCTIONS: You do not need an air compressor. Just apply a little soapy water to the inside of the Grip Puppies and slide them over your existing grips. Allow to dry, then enjoy the ride! 5 Year Warranty: We stand by our Grip Puppy product, offering a 5 year warranty against manufacturing faults or defects from the date of purchase.
