Overhauling and rebuilding cup and cone bottom brackets, hubs, and headsets. Identifying when problems are present and whether they need a simple adjustment or a more involved overhaul.
The third Sunday of every month focuses on cups, cones, and bearings. Classes are free and open to all levels of experience and expertise. There's no need to do the classes in order, or go to the beginner's class before any others. As always, people can use the tools to repair their own bikes, though they cannot expect guidance for the mechanics. People who want to work on their own bikes and need the help of a mechanic should come to the Open Workshop every Thursday nite.Workshop may last shorter than 2 hours.
