A 2017 patent was recently discovered by the British cycling publication Bike Radar, evidencing that Campagnolo might be fast at work in developing a 12-speed drivetrain. To wit.
“Housed in a conventional bicycle having wheels and frame of a standardized size, a bicycle rear wheel sprocket assembly has twelve sprockets in a twelve sprocket assembly. The twelve sprocket assembly is configured to be mounted to a bicycle freewheel hub. The freewheel hub rotates about a rotation axis and has a spoke attachment portion and a frame fastening portion which are spaced apart by an axial distance. End sprockets of the twelve sprocket assembly are positioned within the axial distance.”
Furthermore, images contained in the patent depict a 12-speed cassette in the following ratios:
While the patent does not specifically reference the introduction of any other new components such as derailleurs and shifters, possibility of adapting existing mechanicals to work with a new cassette design is a likely premise.
It will be interesting to see if Campagnolo responds to this recent discovery.
In the meantime, we’ll keep an ear to the track for anything coming from Vicenza.
