Having a good pump is a staple for any ride or any household that owns a bike. Having your tires properly inflated for the type of ride you have chosen, could make the difference of suffering from the beginning to whizzing along faster than you thought imaginable. Or between having great grip on gnarly rocks and roots to no grip on them. When you get your pump that inflates schrader or presta valves, all you need to know is the tire pressure for the type of terrain and riding style you are riding for. Now go have fun.
