Readers ask: How To Adjust Front Shocks On A Mountain Bike?

How much air should I put in my front shock?

Eyeball it or use a ruler to measure. If less than 30 percent of the stanchion is showing below the o-ring, unscrew the valve cap on your shock and, using a shock pump, add air —about 10 PSI at a time.

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 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 PSI should my FOX shock be?

Add air pressure to the main air chamber in ~50 psi (3.4 bar) increments, slowly cycling the shock after every 50 psi (3.4 bar) addition. Set your main air chamber to between 50-300psi to prepare to set sag as described in the “Setting Shock Air Pressure ” section below.

How much air should I put in my suspension?

For the rear shock, start at about half of your rider weight for air pressure. You will have to adjust from here, but you will want to achieve the proper SAG for your frame, as recommended by your frame manufacturer. Typically this is somewhere between 30-40% of overall travel.

What PSI should my rear shock be at?

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.

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.

Can I put a longer rear shock on my mountain bike?

If you buy a shock that is too long for your bike, it will work well, but it can also damage it. The shock may be too long if your rear tire has moved at all after you installed it. Parts of the frame of your bike may also touch that aren’t supposed to, causing unnecessary damage.
