To calculate your sag percentage, divide the static travel by the total length of the shock and multiply by 100. Most manufacturers recommend that you set your sag somewhere between 25 to 35 percent.
How is SAG calculated on a mountain bike?
get off carefully and measure between the o-ring indicator and seal. that’s how much sag you have. as a percentage, it’s that amount divided by your shock’s total travel. so 12mm sag on a 50mm shock = 24% sag.
How is sag measured?
Sag is calculated by averaging L2 and L3 and subtracting it from fully extended. With a Sag Master there is no need to subtract since the tape was locked and zeroed at full extension. Note: FREE SAG is the amount the bike compresses with the weight of the bike only – no rider.
How much sag should my bike have?
Whichever method you choose, set the recommended sag (typically 25 – 30% in the rear) and ride the bike to see how it feels, then make any adjustments as needed.
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 do you measure a SAG coil?
Measure the eye-to-eye distance of your bike’s shock mounts. With the help of a friend, mount the bike in your normal riding position with your normal riding gear and measure eye-to-eye distance again. The difference between the two measurements is sag. To increase sag, turn the preload adjuster counter-clockwise.
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.
How do I adjust my mountain bike forks?
Setting rebound damping on your fork
Stand next to your bike and compress the fork with your body weight. Quickly release the fork and let it bounce back. Adjust the rebound until the fork rebounds as fast as possible without causing the front wheel to ‘jump’ off the ground.
How much sag is trail riding?
The amount of recommended sag will vary depending on the type of bike that you ride. Typically, enduro/trail bikes fall between 25% – 35% recommended sag, while downhill bikes can be up to 40% recommended sag.
Where do you measure sag from?
To determine rider sag put your bike on a stand with the wheels off the ground and measure the distance from the rear axle to a fixed point near the rear fender/side panel. The fixed point should be along the arc that the axle travels when the shock is compressed.
How is free sag measured?
How do you measure sag? Put your bike on a stand with the rear wheel off the ground, and measure from the rear fender to the rear axle. Write that number on your buddy’s forehead. Next, remove the bike from the stand and climb on board.
What does sag mean in biking?
Sag is the amount the shocks move under the weight of your body, bike shoes, helmet any other gear you carry when you’re just sitting on the bike. Having it properly adjusted ensures the shocks are neither too stiff nor too soft.
What’s more important static sag vs rider sag?
While rider sag is obviously the key measurement, static sag is just as important, especially when setting up a new bike for a particular rider as it will tell you if you have the correct spring rates installed. It can also tell you al lot about the health of your suspension.
How important is sag?
Sag is important and it effects alot of handling attributes. The reason why we have sag in the first place regardless of balance and steering is to allow the shock to travel over the terrain and follow the ground.
