Maintaining your bike is key to keeping it in ride-ready condition. Crucial to efficient cycling are fully-inflated tires. When a tire begins to deflate, not only does it cause damage to the wheel, it makes turning those tires over more difficult when pedaling and cause you to exert unnecessary effort.
Tire pumps ensure your tires stay in prime condition. Floor pumps stay wherever you store your bike and are perfect for right before your ride. Portable pumps are important to carry with you on rides should anything happen. Even if you don't have a proper patch kit available, a pump can save your tire enough to finish a ride when you get a flat.
