Mention of half-step in this thread prompted me to go and refresh my memory on what was the purpose of it. While reading I stumbled on this quote: "I have seen bicycles fitted with rear derailleurs which required and permitted the rear wheel to actually be moved while riding as part of the shifting procedure.", full text here https://cs.uwaterloo.ca/~arpepper/Cy.../halfstep.html
Can anyone point me to where I can find more information on such system?
