*Servicing the Yeti Infinity Link more frequently than this is excessive, messy, and unnecessary.

 

Do Not disassemble the Yeti Infinity Link. The Yeti Infinity Link is built with some preload on the shaft bearings which is required to keep the mechanism free of play. The leverage ratio between the wheel and link movement is so great that any friction felt between the shafts and bearings can be considered insignificant.



Do Not disassemble the Yeti Infinity Link as special tools are required for proper assembly. Improper assembly can lead to damaged parts that may not function as expected which can cause loss of control of the bicycle resulting in SERIOUS INJURY OR DEATH.

Servicing the Yeti Infinity Link

Servicing the Yeti SB100 Switch Infinity Link involes injecting grease into the grease Zerk fittings. You will need a needle-style grease gun and Yeti's heavy duty grease which can be found at your local Yeti Dealer or on Yeti's website: Yeti Grease »

Different regions and riding conditions may benefit from the use of alternative greases. In all usage conditions, Heavy Duty Yeti grease will suffice.

Step 3

The needle-type grease fittings of the Yeti Infinity Link require a generous push to make a proper seal while injecting grease.

Use your needle-type grease gun to inject a Heavy Duty Molybdenum grease (such as Mobil XHP 222 Special or similar through the Zerks housed in the Main Pivot bolts. Inject until you see grease extruding from the shaft seals.
