Bikesmith provides specialized components, tools, metalworking and design services that are outside the scope of the typical bicycle shop.

If you need "normal" repairs or parts, there are many fine bike shops in the area.

I also do gas and TIG welding and brazing, including all of the typical braze-ons common to upright bikes;

    Water Bottle Bosses and Pump Pins
    Eylets and Rack Mounts
    Cable Guides and Stops
    Cantilever/V-Brake Pivots
Additionally, I fabricate custom fittings, and modify standard braze-ons, for the specialized needs of recumbents.
One of these days I need to build a page showing some examples.
