Wow. That's more than all my bikes together. And I have a lot of bikes.


Not sure if this is what this thread is about, but check out the 2-speed top tube quadrant shifter I made for the Trivelox derailleur on my Fothergill:




The shifter itself, and its housing, is made from scrap aluminum, most of it from a Razor scooter. The clamp is also, partly, from a Razor scooter and part of a coaster brake reactor band.
