Rip Tides WFB bushings are produced using their "World Fastest Bushings" material. This WFB material is formulated with a unique lubrication, which explains the occasional white residue found on the surface of the bushings.
If you desire a seamless response from your bushings and wish to have command over them rather than allowing them to dictate your ride, these bushings are certainly worth trying.
They come in a broad selection of durometers to suit your weight, skill level, or even to match the colours of your setup.
