Keep your Switch Infinity suspension system performing at its peak with the official Yeti Cycles grease, specially formulated for the extreme conditions of full-suspension mountain biking. This Heavy Duty Molybdenum (MoS2) grease ensures optimal lubrication of the bearings and bushings in your patented Switch Infinity system, guaranteeing smoothness, longevity, and reliability on all terrains.

Technical Overview

Developed in partnership with FOX Factory, this lithium NLGI grade 2 based grease enriched with Molybdenum offers maximum protection against friction, wear, and corrosion. Its 3.2 oz (95 ml) tube format provides multiple servicing intervals for your Switch Infinity mechanism. Compatible with conventional lithium and Molybdenum greases, it meets the strict technical specifications required by Yeti to maintain your frame under warranty.

Technical Highlights

• Heavy Duty Molybdenum (MoS2) formulation: Extreme pressure resistance and exceptional anti-friction properties, ideal for bearings and bushings in the Switch Infinity system under load.
• Lithium NLGI grade 2 base: Optimal consistency for injection via needle grease gun, ensures adhesion and retention in Zerk fittings without excessive bleeding.
• Water and contamination resistance: Effectively repels moisture and dirt, protects bearings even in intensive muddy and rainy conditions.
• Recommended by FOX and Yeti: Manufacturer-approved formulation for all SB models equipped with the Switch Infinity system (SB100, SB130, SB140, SB150, SB160, SB165).
• Flexible service interval: Yeti recommends regreasing every 20 hours minimum, but the interval can be extended depending on usage conditions (overly frequent servicing is unnecessary and messy).

Applications and Compatibility

This grease is specially designed for the Switch Infinity system, the patented translating pivot mechanism that equips Yeti Cycles full-suspension mountain bikes. It is injected via a needle grease gun (sold separately, ref. 200020250) into the Zerk fittings of the system until grease is expelled through the axle seals. Compatible with Mobil XHP 222, Chevron Moly Grease EP 2, Valvoline SynPower or equivalent NLGI 2 Molybdenum greases. Also suitable for regreasing main pivot bearings (Enduro Max) after thorough cleaning.

Application and Pro Tips

• Essential preliminary cleaning: Before injection, thoroughly clean the Zerk fittings and mechanism with isopropyl alcohol or soapy water to prevent introduction of abrasive particles.
• Injection technique: Apply firm and generous pressure with the needle grease gun to ensure a tight seal with the Zerk fittings. Inject until grease emerges from the seals, then wipe excess immediately.
• Service frequency: Recommended minimum interval of 20 hours of riding. In extreme conditions (mud, high-pressure washing, heavy rain), reduce to 15 hours. Do not over-grease: excessive servicing can introduce contamination.
• Tube storage: Carefully close the screw cap after use to prevent drying. Store at room temperature, away from excessive heat (max 120°F / 50°C).
• Economical alternative: NLGI 2 Molybdenum greases such as Mobil XHP 222 Special, Chevron Moly EP 2, Sta-Lube SL3330 or Liqui Moly LM47 can be used as alternatives, but Yeti grease guarantees full compliance with manufacturer specifications.

Switch Infinity Service: Complete Procedure

On metric models (SB100, 130, 140, 150, 160, 165), accessing the Zerk fittings requires partial disassembly of the main pivot: remove the collet wedge bolt (5 mm Allen key), then the collet axle (10 mm Allen key). Tilt the swingarm upward to expose the two Switch Infinity fittings. Clean thoroughly, inject grease until seepage occurs, wipe excess, then reassemble. On older imperial models (SB4.5, 5, 5.5, 6), fittings are directly accessible. Never disassemble the Switch Infinity mechanism: it is factory pre-loaded and requires special FOX tooling. Incorrect disassembly can cause serious malfunctions.

Why Choose Official Yeti Grease?

Regular maintenance of the Switch Infinity system with this grease extends bearing life, maintains suspension sensitivity, and preserves chassis rigidity. Used by professional Yeti/FOX Factory teams (51 EWS stage wins, 12 EWS races, 1 national championship on SB150), it has proven itself in competition. Its 3.2 oz tube format allows approximately 3 to 4 complete services, equivalent to a season of intensive riding. Choosing Yeti grease guarantees manufacturer compliance and the longevity of your investment.
