  • Quality, and replaceable components

    one place where many single speed manufacturers save costs is on components. Often manufacturers use non-standard sizings that are cheaper to produce but more expensive to replace. 6KU use more standardised components making them easier to replace and increasing the lifespan of your bicycle
