When it comes time to regrip your handle, you can easily purchase a new traction grip on line. Just search for Grays Twintex Grip for Hockey Sticks. They come in a variety of colors. I can also source them from PFC in Australia, but they may be more expensive because of the shipping cost. The cushion grips are not available in the USA, but can be bought on this website. The top grip is usually black as it gets dirty with use.
Next you will need the top rubber gasket and cap to close off the handle tube. The rubber gasket needs to be 'shrink-wrapped' around the top - a hairdryer will do the trick. Last, the top button closes off the top of the handle.
I am a happy to provide these for just the cost of shipping which is $5.
