WHY IS YOUR MOUNTAIN BIKE SEAT HEIGHT SO IMPORTANT?
Setting your seat at an improper height is not only uncomfortable but will eventually also cause injuries. The two most common problems that result from bad seat height are knee pain and saddle sores. You really want to avoid both of them.
Knee pain is caused by either a seat that’s too high or one that’s too low. Seats that are too result in overextension of your knee. Seats that are too low require you to put more pressure on your knees when pedaling.
Another issue that may present itself if your seat is too high is saddle sores. This will result in legs that are fully extended at the lowest point in the pedal rotation. When pedaling, this will lock out your legs and make your hips rock from side to side. It’s this hip movement that eventually causes scrapes, chafing and other superficial wounds on your butt—the so-called saddle sores.
