Cool Tech: VYRO's Multi-Segment Gear System 15

This is pretty cool. It's another possible solution to dropping the front derailleur once and for all.

The highlight of the VYRO gear system is the four piece segmented chainring. Each of these segments are mounted on top of a tilted pin. The segments are pivoted into the chain line and forced into operation (pause the video at 2:08 to see it in action). Gradually, the rest of the segments are fed into or out of the chain line until the gear is changed completely. This process can happen at any time, even during hard loads, because the chain is always moving in a straight direction. It only takes 1/4 of a turn to start the movement, providing near instant shifts.



The whole assembly is sandwiched by inner and outer guide rings that supposedly eliminate the need for a traditional chain guide.
