Claims20
A device, comprising:
- a linkage system, including:
- a lower idler configured to be mounted on any member of a non-single pivot linkage that is not a front main frame, wherein a single pivot has only two rigid bodies that are part of the linkage, so that a rear axle path is a portion of a circle.
A device, comprising:
- a linkage for a bicycle, including an upper idler configured to receive a chain of the bicycle, the linkage configured to control a distance between a center of the upper idler and a center of a chainring, the change in this distance ranging from plus 100 mm and minus 100 mm.
A device, comprising:
- a bicycle, including:
- a main frame having an upper main frame pivot and a lower main frame pivot;
- a swingarm having an upper swingarm pivot and a lower swingarm pivot;
- and
- a dual link suspension system coupling the main frame to the swingarm, wherein the upper main frame pivot is above and in front of the upper swingarm pivot, and wherein the lower swingarm pivot is above the lower main frame pivot.
