How to Adjust the Softness and Hardness of Mountain Bike Suspension?
2 Answers
Soft frame design allows adjustment through the threaded ring on the rear suspension. Turning it clockwise compresses the spring, making the suspension harder. Conversely, turning it counterclockwise makes it softer. The left side of the front fork typically uses a spring to provide suspension force, while the right side uses damping oil to control the compression and rebound speed of the suspension. This type of suspension also comes in different grades. The softness and hardness of air suspension are adjusted by the air pressure in the air chamber. To make it harder, use a pump to increase the air pressure; to make it softer, release some pressure.
I find adjusting the stiffness of mountain bike suspension quite interesting, and it takes some time to get the hang of it. First, you need to locate the suspension components, usually on the front and rear forks, where you'll find adjustment knobs or air valves. The stiffness adjustment is mainly to adapt to different terrains and personal preferences: for example, a softer setting absorbs more bumps on rough trails, enhancing comfort, while a firmer setting is better for smooth roads or climbing, saving energy and increasing speed. Before making adjustments, it's best to check the recommended weight range—most suspension systems have markings. Sit on the bike to test the sag, ensuring it compresses about 25%. Then, use small tools to fine-tune the air pressure valve or damping knob. After each adjustment, test it on a small slope in your neighborhood to check braking and steering stability. Don’t forget to regularly inspect air pressure and seal integrity to prevent leaks.
