How Much Psi Should I Have In My Rear Shock?

by | Last updated on January 24, 2024

, , , ,

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.

How much psi should I put in my bike shock?

Start with where you should be in the manual, assess how much travel you’ve used after a typical ride. If you are not cycling through your suspension, let out 5 psi at a time per ride .

What psi should my FOX shock be?

Do not exceed 300 psi (20.7 bar) , the maximum FLOAT air pressure! Remove the pump. Sit still on the bike in your normal riding position, using a wall or a tree for support. Pull the sag indicator o-ring up against the rubber air sleeve seal.

Is 300 psi shock pump enough?

The RockShox shock pump has an air pressure support of 300 PSI , which should be plenty for all types of suspensions. It’s ideal for maintaining your bicycle’s shock absorbers since it delivers high pressure at low volumes for the precise calibration of your rear suspension and air fork.

How much air should I put in my MTB suspension?

Measure the amount of travel is you don’t know how much travel you have. Ideally for an XC set-up, you want to start with 25% sag . Push the rubber O-Rings down the base of the shock and fork. Have your friend hold up your bike facing you and holding the handlebars with the front tire between their knees.

What PSI is Fox DPX2?

3. Do not exceed maximum air pressure: FLOAT DPS and DPX2 air shocks have a maximum air pressure of 350 psi .

How much PSI is a Fox Float?

Suggested Sag Measurements Travel 25% sag (Firm) 30% sag (Plush) 57 mm (2.25 in) 14 mm (0.56 in) 17 mm (0.68 in) 63 mm (2.5 in) 16 mm (0.63 in) 19 mm (.75 in) 76 mm (3.0 in) 19 mm (0.75 in) 23 mm (0.90 in)

How important is a shock pump?

A shock pump makes a seal with the valve stem before it actually opens the valve. This prevents air loss when you remove it . Due to the small volume of the air chamber in forks and shocks, the amount of air loss a normal tire pump would allow would be unacceptable.

Can a shock pump be used for tires?

Though you could technically use a shock pump to inflate a tire, you’ll be going at it for a LONG TIME because shock pumps push such a small volume of air.

Why do you need a shock pump?

For most modern mountain bike shocks, that means adjusting the air pressure inside the spring – and to do that you’ll need a shock pump. Compared with a normal tyre pump, most shock pumps are designed to reach up to 300psi without straining a muscle or busting a seal.

What PSI should MTB 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 pressure should my front forks be?

On the biggest stuff you hit, you should be close to bottoming or bottoming but not hard. If you’re running into not using all the travel, drop the pressure in small 5psi decrements. If you’re bottoming, raise pressure a bit.

How do you put air in rear shocks?

Without any air in the shock, it should just work as a regular shock . The air bladder and the dampening section are totally separate.

How much air should I put in my Fox forks?

Sag range should be set to 15–20% of total fork travel . Unscrew the blue air cap on top of the left fork leg counter-clockwise to expose the Schrader valve.

How do you set a SAG Fox?

  1. Unscrew the blue air cap on top of the left fork leg counter-clockwise to expose the Schrader valve.
  2. Attach a FOX High Pressure Pump to the Schrader valve.
  3. Pump your fork to the appropriate pressure as listed in the ‘Suggested starting points for setting sag’ table below, then remove the pump.

How do you inflate a Fox rear shock?

Turn the 3-position lever to the OPEN mode. Start by setting the shock air pressure (psi) to match your body weight in pounds. With the air pump attached to the shock valve, slowly cycle your shock through 25% of its travel 10 times as you reach your desired pressure.
