I have an imaginary bicycle for sale, and it’s not cheap. This bicycle has qualities that are not considered possible with known technology. Namely to control a bicycle chain (1/2" pitch, rolling chain) in a flat plane, while permitting riders their preferred cadence for any road condition any time. This new bicycle transmission eliminates the derailleurs, and other associated parts. In their place a new type of chain bearing/powertrain has been invented that is sandwiched between thin metal disks where the chain bearing controls the bicycle chain. Riders will now feel the tire/road interaction directly through the drivetrain just like a single speed bicycle but with a ratio dense transmission (infinitely variable).
With the elimination of the derailleur the chain has no slack, and you will feel the road as if you’re on a fixed speed bicycle, yet have the luxury of setting your own cadence, any time, any where. This one quality will transform every bicycle rider’s experience.
Competitive athletes will now be able use any cadence they want, for any road condition for the fasted ride. The rest of us now will have the luxury to choose the easiest pace for the ride ahead.
This new bicycle drivetrain will make every bicycle ever made obsolete. This innovated drivetrain with multiple utility inventions, and for the first time the use of “hardliquid” to provide fluid sequential shifting, will revolutionize and dominate the global bicycle marked.
