Get your head straight.
Building your own bicycle, or doing your own maintenance on your machine, can be immensely satisfying. The right tools for the job are critical, however, and the lack thereof can lead to some hazardous improvisation, particularly when it's almost midnight and you've had an adult beverage or two. Install your headset cups improperly, for example, and the results can be terrible, including a permanently damaged frame, or face. The Unior Headset Bearing Cup Press is designed to safely and properly install headset bearings or bearing cups into head tubes from 1, 1.125, 1.25, or 1.5 inches in diameter. It's made of hardened, tool-grade steel from which Unior makes many of its best tools, so it will last as long as you keep riding and wrenching.
