The Yeti Cycles professional maintenance kit combines an ergonomic grease gun and a complete 3.2 oz (90 g) tube of Heavy Duty Turq grease, specially formulated to maintain the Switch Infinity system in optimal working condition. Designed for demanding riders who want to extend the lifespan of their rear suspension and guarantee maximum performance, this professional set allows precise application without waste or contamination.

Technical highlights of the Yeti grease gun

• One-handed design: ergonomics designed for easy access to confined areas and suspension pivots, even in mobile workshops or in the field
• Specialized needle for Zerk fittings: the gun features a fine tip that connects perfectly to the Switch Infinity grease ports, allowing you to push the fitting's closing ball to inject grease directly into the bushings and seals
• Precise dosage: each press delivers approximately 2 ml of grease, ensuring controlled application without excess or unnecessary purging of existing grease
• Sealed system: the grease tube remains airtight, preventing any contamination from dust, moisture or dirt — a major advantage over traditional open containers

Heavy Duty Yeti Turq grease: exclusive formulation

• Specially developed for Switch Infinity: high-performance molybdenum-based (MoS₂) grease, designed in partnership with Fox to withstand the extreme stresses of suspension systems under high loads and rapid movements
• Enhanced protection: incorporates advanced rust and corrosion inhibitors, as well as extreme pressure additives to guarantee the longevity of bushings, seals and Kashima rods
• Versatility: also suitable for bottom bracket, headset, hub bearings, suspension pivots, pedals, threads and all metal interfaces requiring durable lubrication
• Suitable for varied environments: Heavy Duty formula sufficient for all weather conditions and terrain types (dry, wet, muddy), although extreme environments (highly abrasive British mud) require regular and careful cleaning of Zerk ports before regreasing

Switch Infinity system maintenance: recommended protocol

• Frequency: Yeti recommends maintenance every 20 hours of riding minimum; more frequent greasing is excessive and can lead to grease buildup that attracts contaminants
• Procedure:
  • Clean the outside of the Switch Infinity Link with isopropyl alcohol or soapy water and a clean lint-free cloth
  • Carefully clean the Zerk fittings to avoid introducing dirt
  • Insert the gun needle firmly into each of the two Zerk ports
  • Inject grease until you see a slight excess emerging from the rod seals (proof that the grease has circulated properly)
  • Immediately wipe off excess grease with a clean cloth
• Warning: never disassemble the Switch Infinity Link — it is assembled with specific preloads and dedicated tools; incorrect assembly can result in loss of control and serious injury

Compatibility and extended applications

Although this kit is optimized for the Switch Infinity system on Yeti mountain bikes (SB100, SB130, SB140, SB150, SB165, SB4.5, SB5, SB5.5, SB6), it is also suitable for:

• Lubrication of suspension pivots with Zerk grease ports
• Maintenance of headset, bottom bracket and hub bearings
• Greasing pedal and crank axles
• Threads and metal interfaces subjected to high loads

Why choose the official Yeti kit?

• Compatibility guarantee: grease and gun validated by Yeti and Fox, eliminating any risk of unsuitable product
• No waste: ideal tube size for regular maintenance without storing industrial volumes
• Maximum efficiency: the specific needle ensures a perfect connection to Zerk fittings, avoiding leaks and ineffective application
• Signature Turq color: recognizable Yeti design, guarantee of quality and authenticity
