Polytube 1000

Properly-applied grease will protect and extend the life of a bicycle's components while improving performance. Park Tool's PolyLube 1000 polyurea lubricant was developed specifically for bicycle maintenance and repair, and can be used with any type of ball bearings, threads, or press fit applications found on a bicycle, including headsets, bottom brackets, cranks, pedals, and hubs. PolyLube 1000 repels moisture and has an extremely high shear strength to protect vital parts under extreme conditions. Highly tenacious synthetic-base grease. Waterproof, inert (will not react in contact with other greases)
