Readers ask: How To Adjust Shocks On Mountain Bike?

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.

How much air pressure should I put in my air shocks?

The proper pressure of an air shock should be between 35 and 75 PSI. If it is any lower than this, the shocks will need to be filled with air.

How much air do I put in my mountain bike forks?

Set up the fork to a pressure where you have between 25%-30% sag. Say, the amount the fork compresses when you get on the bike in normal riding position, has to be like a fourth of the total travel. If your Recon is 130mm travel, it should sink like 36-38mm with your weight on.

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.

Does increasing preload increase 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.

How does spring preload affect handling?

Preloading is not the same as using a stiffer (higher spring rate) spring. Preloading does not change spring rate but preload does change the force to start moving the shock and high preload dramatically reduces shock performance over smaller bumps and makes for a more harsh ride and worse traction.

What PSI should rear shocks be?

Add Air. A good rule of thumb for inflating air shocks is to add 1psi of air for every pound you weigh. Therefore if you weigh 140lb, then begin the set-up process at 140psi. Remember to use an accurate shock pump, as old pumps often have leaks and faulty pressure dials.

How do you adjust the rear suspension on a mountain bike?

Setting your rear shock sag

  1. Bounce firmly up and down to charge the negative spring and free up the travel.
  2. Assume your normal seated position and after allowing the bike to settle for at least 5 seconds have your assistant push the rubber O-ring on the shock stanchion up (or down) to the rubber wiper seal.
