Always inflate your tires for the riding conditions. For paved trail riding, be sure tires are inflated to their maximum recommended psi (pounds per square inch). This information is found on the sidewall of all tires and is expressed in a range, for example: 35 - 60 psi. The higher number is for pavement or hard-packed, smooth riding surfaces. The lower number is the lowest recommended psi for rougher dirt trails. Any lower and you risk a pinch flat! (Pack your spare tube!)
Remember, it takes more energy to pedal when your tires are low, so pump 'em up for spring pavement riding!
When coasting on your mountain bike, keep your pedals at the 3 & 9 positions. In other words, keep your pedals level with the ground instead of riding with one foot up and one down. This way, if you approach a rock or root or other obstacle, your pedals are in a better position to clear that obstacle (rather than having your pedal smack the rock!)
When descending, this pedals-level position makes it easier for you to slide your butt back off the saddle so there’s less weight over the front of the bike.
