A very nice feature of a top tier randonneur bicycle is to have a stem cap mounted lightswitch. This option was typically available only on very special bicycles such as our cost-as-no-object Rene Herse bicycles.
But by popular demand - and through a lot of trial and error and design work with our local machine shop, we finally have a stem cap light switch for sale!
The requirement is that you have a 1" threadless steerer. We're assuming you will be using a typical 1 1/8" stem though, so therefore you will be using a shims on the steerer. In place some of the spacers going around your shim, you will need to use the adjustable headset spacer which IS INCLUDED that will allow you to pre-load the headset against your stem. The only downside at this time is the adjustable headset spacer is black. Perhaps some easy off or time polishing will enable you to make it shiny. We also will include a few 1" to 1 1/8" shims as well.
The light switch package comes with the actual high quality Japanese switch.
Note that this is not the easiest package to install. You need to hook up wires, run them out the bottom of the steerer tube, and do all sorts of stuff to make the installation. But for those who are tech savy or who are working with builders who are, this is an amazingly beautiful and function assembly. And the parts which we make are MADE IN THE USA!
