Grease

Stub — to be filled out.

Covers semi-solid lubricants used on bearings, threads, and assembly points.

Sections to add (TODO)

  • Bearing greases
    • Lithium-complex (general purpose, e.g. Park PPL-1, Phil Wood waterproof)
    • Calcium sulfonate (high-pressure, marine, e.g. Phil Wood Tenacious)
    • Synthetic PFPE (e.g. Krytox) — for ceramic/high-temp bearings
    • NLGI grade explained (0 / 1 / 2 — most bike grease is NLGI 2)
  • Assembly grease / waterproof grease — headsets, bottom brackets, seatposts (steel-on-alu only)
  • Anti-seize compounds
    • Copper anti-seize — pedals, steel-on-steel high-torque
    • Nickel anti-seize — high-temp
    • Aluminum anti-seize — most common, OK for most fasteners
    • NEVER on carbon parts
  • Carbon assembly paste (friction paste with grit) — seatposts, stems, bars
  • Threadlockers
    • Loctite 222 (purple, low strength) — small bolts, derailleur hangers
    • Loctite 243 (blue, medium) — pedals, disc rotor bolts, chainring bolts
    • Loctite 263 (red, high) — rarely on bikes; permanent
  • Compatibility warnings
    • Lithium grease + DOT brake fluid → contamination
    • Petroleum grease + EPDM seals → swelling
    • Copper anti-seize + galvanic corrosion on alu
