How To Ajust A Bicycle Seat

Need to adjust a bicycle seat? A well-positioned seat can mean the difference between a safe ride and one prone to possible injury. There are 3 main types of adjustments to be considered when adjusting a seat. Those are seat height, seat angle, and front-to-back adjustment.

1. Seat height is determined in relation to how bent or straight your legs are while you are pedaling. Underneath the seat is a post, called a seat post, that slides into the frame of the bicycle .A bolt, called a pinch bolt, is on the side of where the frame and seat post meet. Loosen the pinch bolt and twist the seat to raise or lower as needed. Tighten the bolt when finished.
2. Test the newly adjusted height of the seat by getting on the bike. If your leg remains too bent or too straight, then the seat is needs to be adjusted. Ideally, your leg should be slightly bent when the ball of your foot is on top of the pedal, and the pedal is at its lowest point in the rotation.
3. Seat angle should be in a horizontal position, but within that position, there are differences for individual comfort. Loosen the seat clamp under the seat just enough to move the seat around. The angle of the nose of the seat can be moved upward or downward based on personal preference. Before tightening the clamp, check to see if any front-to-back adjustments need to be made.
4. Front-to-back adjustment is based on the distance between you and the bottom bracket. The seat clamp tightens to two rails that allow the seat to slide forward and backward. Find the seat position that allows your knee to be directly above the pedal spindle when the ball of your foot is on the pedal, and the pedal is at its forward-most point. Once the adjustments are made, tighten any loosened clamps.
