DEFEAT RUST
An important part of designing a great board is choosing the right materials for the job. MBS utilizes state of the art materials such as fiberglass composites and high-grade steel and aluminum alloys to build the strongest and lightest mountainboards available. But every material has advantages and disadvantages. MBS uses 4130 CroMoly steel for all of our axles because this is the strongest and most economical material available for the job, but like most types of steel, CroMoly can rust after time.
Rust, which is caused by the oxidation of the iron contained in the steel, is typically superficial and can be cleaned off easily with an oily rag. The best way to minimize rust is to keep all steel parts (screws, nuts, springs, axles,...) clean, dry, and well lubricated with oil such as Tri-Flow. How often this needs to be done depends on the environment in which you live and ride.
Due to the wet and salty conditions, coastal areas take an especially hard toll on steel parts. Therefore, it is important for coastal riders to clean, dry, and oil steel components after every ride.
For people that live and ride in dry climates, keeping your equipment rust-free is easy. Just clean, dry, and oil your steel components once at the beginning and end of each season. If you see any rust during the season, just wipe it off with an oily rag.
