You apply chamois butter to your skin in order to prevent chafing and saddle sores during extended biking. Typically, you apply chamois butter between your skin and the chamois pad of cycling shorts to reduce friction.
New formulas aren’t greasy, they are clean, and they actually kill bacteria or fungus. They are well liked by many long-distance cyclists and triathletes, but are suitable for indoor riding as well as for use in spin class. They can renew and extend chamois pads’ lifetimes, especially repeatedly after use and washing them.
