The definition of water-resistant grease is supported by the American National Standards Institute (ANSI), which states that water-resistant lubricants repel water and maintain their lubricating properties even in wet conditions.
The underlying causes for the importance of water resistance in bearing grease are primarily related to the operating environment of mountain bikes. Mountain bikes often encounter wet and muddy terrain. This exposes the bearings to moisture, which can compromise lubricant effectiveness. Without water resistance, the grease can break down, leading to increased friction and wear.
Technical terms such as “viscosity” and “thixotropic” apply here. Viscosity measures a lubricant’s thickness and its ability to flow. Thixotropic means the grease can become less viscous with shear stress, allowing it to move easily in bearings. High-quality grease maintains its viscosity despite water exposure, ensuring effective lubrication.
Mechanisms involved in water resistance include the formulation of the grease. Water-resistant grease typically contains additives that enhance its performance. These additives form a barrier against moisture, preventing water from mixing with the grease. The proper formulation also allows the grease to cling to surfaces, reducing the risk of washout during heavy rains or when riding through puddles.
Specific conditions that contribute to the necessity for water resistance include riding in wet weather, traversing through streams, or cleaning the bike with high-pressure water hoses. For example, if a rider frequently rides in rainy conditions, standard grease can wash out quickly, whereas water-resistant grease remains intact, ensuring continuous protection for the bearings.
