Now that the Nivex derailleurs have been in production for a while, Rene Herse is taking analog shifting to the next level with the Floating Chain. This system is lighter, has less resistance and costs far less than all derailleur systems available today.
Most cyclists need only three gears: one for uphills, one for flat roads, one for downhills. It makes sense to put these three gears on the front. So we've turned around the one-by and put all the gears on a triple crank. That allows us to do away with rear derailleurs. For riders who are looking for the ultimate in simplicity, moving the chain by hand is an option. That way, you get a completely derailleur-less drivetrain!
Today in the RH Journal, Jan explains how the Floating Chain works—how to keep the chain from skipping without a chain tensioner—and why the bike industry hasn't promoted it, even though it was invented decades ago and has many advantages over derailleur and hub gear systems.
