How do you set a fork sag on a mountain bike?

What should your sag be set to on your mountain bike?

Most manufacturers recommend that you set your sag somewhere between 25 to 35 percent. If your sag is higher or lower than that, you need to make some adjustments by attaching your shock pump and increasing or decreasing the air pressure in the shock and running the calculation again.

How do you adjust a SAG suspension on a mountain bike?

Wind off all your rebound and compression damping (if you have it) to the minimum settings. You don’t want the damping interfering with setting your sag. Slide your suspension’s rubber O-ring travel marker down to the seal. Stand up on your pedals whilst leaning lightly against a wall (or tree, or van etc).

How much sag is too much?

For the rear shock – 20% – 30% sag is recommended. For the most part, this can be used across the board for trail bikes and downhill bikes. Again, keep in mind you may want more or less sag depending on your bike, weight, and riding preferences. For the front fork- 10% sag is recommended.

Does preload affect ride height?

The suspension may feel stiffer when preload is increased, but that’s because adding preload compresses the spring, so it takes more pressure to move the suspension any further. Adjusting preload simply determines the motorcycle’s ride height. … Basically, when ride height is overly high there is too little sag.

What does preload mean on a mountain bike?

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 forks?

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.) Lighter riders should use less(-) preload.

What PSI should my mountain bike shocks be?

Often yes, usually rear shocks run 100-200psi, but fork psi varies a lot, depending on the design. Get the sag around 25% (maybe slightly less sag in the front than the rear) and see how it rides (that’s what really matters), adjust on the trail as needed.

What is high speed rebound?

High Speed Rebound is a damping adjustment that is controlled via a dial, when externally adjustable. Turning the dial in the Jackalope or ‘–’ (minus) direction reduces the amount of High Speed Rebound damping and the suspension will extend faster.

How do I set my SAG?

To change the sag, use a long punch and a large hammer to loosen the spring locking nut on the shock. 4. Then, turn the spring with your hand to adjust the rear spring preload. Make sure that when you’re turning the spring, the preload nut is also turning.

How do you measure fork on a mountain bike?

Push the zip tie down to the wiper seal and then compress the fork all the way. This is your total travel. Then fill the fork to your regular pressure, push the zip tie back down to the wiper, and go ride your favorite trail. When you are done measure the distance from the tie to the wiper.
