The preload refers to the amount of sag the shock will allow when the bike is at rest with the rider’s weight bearing down on it. Determining the correct preload is important because if it’s too high, it takes more energy to move the shock and compress the springs, resulting in a harder and desensitized shock system.
What does preload do on a mountain bike?
Preload is used to adjust the shock or spring to the correct range of operation within the suspension’s travel-more preload will raise the bike up on its suspension, keeping you near the top of its travel. With less preload, the bike sits lower and closer to the bottom of its suspension travel.
What is lockout with preload?
Preload will adjust how stiff the fork is. More plush ( soft), or hard to compress. lockout will LOCK the fork out, as a rigid fork ( no suspension) would be like. Which makes it a no front suspension bike.
How does Preload work?
Preload is a measurement of how much a spring is compressed at full extension of the shock. Thread the upper spring adjuster down until it just touches the spring, you are now at 0″ of preload. Every inch you thread it down from there is 1″ of preload. With a 1.0 Motion Ratio that also lifts the vehicle 1″.
Does preload affect ride quality?
See all 9 photos Here, spring height’s been adjusted roughly one inch, introducing more preload (top), but since it’s a linear-rate spring, it won’t affect handling or ride quality—just ride height. … When preload force is greater than the car’s corner weight, trouble’s bound to happen.
What does reload mean on bike suspension?
It’s simply the initial compression of the internal spring in the fork. The more it’s compressed, the stiffer the fork will feel. Bigger preload compresses the spring more, and so it’s best for heavier riders and/or people who need/prefer the stiffer ride (racers etc.)
Why is my suspension so stiff MTB?
Preload is HOW STIFF is the suspension, and it’s related to how much force must be applied to compress it. More preload means you need more force (apply more weight) to compress the fork by a given distance or travel. Speed Rebound is HOW FAST the fork return to it’s uncompressed size after absorbing a shock.
Does adjusting preload change ride height?
Adjusting preload simply determines the motorcycle’s ride height. … Basically, when ride height is overly high there is too little sag. The bike rides near the top of its suspension travel, it’s stiff, uncomfortable, and if you’re vertically challenged you may have trouble reaching the ground.
What is a lockout on a mountain bike?
A Lockout is a small switch placed atop the front right stanchion of your MTB/Hybrid Bicycle’s suspension which when engaged decreases the low speed compression rate of the front fork, adjustable to the point of being fully rigid.
What is preload on a suspension fork?
Preload pre-compresses your spring so that it takes more/less force to begin compressing the fork. Increasing the preload will increase the stiffness of the fork (like increasing air pressure in an air fork). Decreasing preload will decrease the stiffness of the fork, similar to decreasing air pressure in an air fork.
Why is preload important?
Preload becomes very important for large mechanical and high performance system such as large Telescopes. … By tensioning, preloading increases the natural frequency of a structure, avoiding resonance due to external disturbances. It also prevents buckling if stresses change depending on position in certain systems.
Is too much preload bad?
Preloading more than the minimum to get rid of play is bad. For best shock performance, turn the preload ring until it contacts the spring and then another 1 to 2 turns. No more.
Does preload compress the spring?
Now let’s take the original spring and install it in the fork. As it’s installed, it gets compressed, or preloaded, a small amount. “Preload” (or “preload length”) is the distance the spring is compressed from its free length as it’s installed with the suspension fully extended.
