Is Switch Infinity just a single pivot with a trick?

No: the moving pivot creates a complex virtual pivot, closer to a dual-link system than a single pivot. What's distinctive is that the lower pivot slides vertically instead of rotating, and reverses direction mid-travel.

Does it need a lot of maintenance?

Yes, more than a normal link: the sliding guides are exposed to mud and need periodic cleaning and lubrication to keep their feel. It's the price of its unique mechanism.

Switch Infinity (Yeti): the pivot that goes up and down

Quick answer

Yeti's Switch Infinity swaps the lower link for a pivot that slides vertically on two guides (Kashima, by Fox) and reverses direction mid-travel. That gives high anti-squat at sag (firm pedalling) that drops as it sinks (loose and low kickback). Exclusive to Yeti; it demands strict maintenance of the guides. It is one of the systems.

Almost every system rotates links. Yeti did something odd: slide a pivot in a straight line. And it works.

What it achieves

By raising the pivot in the first third and lowering it afterwards, Yeti gets what every designer is after: high anti-squat where you pedal, low where you hit. The transition is very smooth because the movement is continuous, not a link jump. That's why the SB bikes feel efficient climbing and very loose deep in the travel.

Pros and cons

For

Very smooth anti-squat transition; efficient pedalling + deep absorption.

Against

Exposed sliding mechanism: sensitive to mud, strict maintenance of the guides.

Used by

Yeti only (SB line). Own patent, developed with Fox.

It is not "a single pivot with a trick": the moving pivot creates a complex virtual pivot, closer to a dual-link than to a single pivot. The only truly distinct thing is that the pivot translates rather than rotates.

Frequently asked questions

Is it a single pivot?

No: the sliding pivot creates a virtual pivot, dual-link style. What's distinctive is that it translates vertically.

Lots of maintenance?

Yes: the exposed guides need periodic cleaning and lubrication to keep their feel.
