Why does Turner use bushings (Journal Bearing) instead of the hyped up bearings that other bike brands use?
A. The journal bearing design offers incredible strength and long life with very little maintenance. Bearings are designed with high-speed rotation in mind (skateboard wheels, drill motors etc.) The journal bearing we use has a purpose of holding a very tight tolerance along with carrying a load much greater than that produced by a bicycle frame, these two attributes we feel are essential to a great riding bike. The rear of our frames often gets praise for how stiff it is laterally and how well it tracks through the roots, ruts, and rocks encountered on a mountain bike. Because a bearing found in a bike pivot never makes a full rotation, you rely on two maybe three of the balls in the cartridge to carry the entire load and pressures generated by the rider. Over time this is what creates that “crunchy” feel or “squeaky” sounds people often comment about. Bearings are also made of steel, steel rusts after being exposed to water, grit and grime, again found in our everyday riding. So long
