Mountain bike maintenance skills:  

   In general, as long as the active parts, must frequent maintenance and inspection. But the point is the transmission system, brake system and three-axis (ie, the front and rear axis).

(I) transmission system maintenance: mainly lubrication. The most effective means is to add oil. To remind everyone that the chain should keep its oily sensitive, especially after rain and wading to timely refueling. Before and after the transmission of the moving parts have always oiling.The chain and transmission oil to use bike rust lubricant is the best. Oil can also be ordinary, but less effective. 

(Ii) maintenance of the braking system: the braking system related to the safety of travel, it is particularly important. In addition to holding various activities in parts of the sensitive and reliable, the itinerary should always check clearances and wear brake blocks. Stroke brake blocks on both sides of the gap should be maintained in the range of 2-3 mm. If the gap is too large, it will increase the value of free travel of the brake block so that the sensitivity of the brakes is reduced, if the gap is too small, they might appear to have the brake strength of the phenomenon and increase the intensity of riding, wasting energy. Surface has two or more grooves each brake block, if the grooves to be polished or have been polished, it should be replaced promptly, in order to ensure traffic safety and brake sensitivity.
