New for '22 -- Red bass ball trim!

We’re transitioning from black to red threaded inserts to differentiate our bass balls and proprietary rubber blend from other brands (see images below). Throughout 2022, we will continue to offer both insert colors. If you care which color you get, please specify in your order. Our popular bass balls have an M10 thread, and are compatible with Saddle Rider brand M10 threaded tips as well as M10 tips by New Harmony, Upton Bass, Götz, and others. The red or black inserts are 3/4 inch in diameter, and squeeze into the rubber ball hole which is approximately .61 inch diameter. The ball is 1.4 inches in diameter. These inserts can also be used in standard 3/4 inch crutch tips, but most people prefer to use them in our high-grip rubber balls.
