Lower Your Seat For Off-Road Biking - If you're a road rider who's trying out the trails, start with a slightly lower seat position than you use on your road rig. Most dirt bikes feature 175-mm long crankarms, which provide extra leverage for steep climbs. Because these may be longer than what's on your street sled, position the seat on an all-terrain bike about one to two centimeters lower than your road position. This accounts for the longer cranks and gives you a little leeway (experiment to determine what's best for you), which is helpful riding off road, especially on technical trails. Using a too-high seat can reduce your maneuverability and control and be very tough on your rear end. If you are switching back and forth between the two bikes frequently, adjust the seat on your road bike to match the mountain bike. You'll find the transition between the two much easier when the seat heights are the same. If you have any questions regarding fit, please ask us.
