Our discovery of Rotor’s hydraulic shifting patents turned out to be well timed, teeing up the group’s public debut nicely. Turns out, our technical breakdown of the groups functioning was nearly spot on, so we’ll recap:
By using a completely hydraulic system from the shift lever all the way to the derailleurs and putting the ratcheting mechanism on the derailleurs, Rotor was able to eliminate any slack from the line that could lead to loose shifting. The side benefits of such a system included lighter weight and plenty of functional improvements that simply can’t happen on a cable-driven or mechanical system.
The key to the system is precision and reliability. Hydraulics have been proven in everything from bicycles to airplanes to heavy industry, just not for bicycle shifting until now. Their motivation was to let customers looking at Rotor’s oval rings and lightweight alloy cranksets find an entire group with the same brand. Undoubtedly, it will also give them more opportunities to put the group on pro teams that may otherwise have to opt for SRAM, Shimano or Campagnolo groups simply because of sponsorship programs dictating complete group use. And they hinted we might see some major teams on the group very soon. But that can’t be enough to justify the heavy time, energy and financial commitment the development of such a product can draw from a company. So, it needs create demand based on its merits. Of which, there are quite a few.
