In order for us to ensure your forks are set correctly, we need to know how much sag you are currently running
“Sag” is how far your suspension compresses when you sit on your bike, having the right amount of sag is vital for a proper bike set up. It means the suspension is able to track the ground properly, giving your tyres more grip, while allow the wheel to use all its travel to absorb big impacts likes rocks and tree roots. If your suspension is too soft, it will be unbalanced and compress too much when it’s not needed, and bottom out harshly which will damage your bike. If it is too hard, the wheel won’t be tracking the ground or absorbing impacts and instead transferring the energy to your body.
The amount of sag needed depends on your riding style, basically the more travel your bike has, the more sag you can run. As a starting point we suggest-
Cross country (4”)- 15%
Trail riding/All mountain (4-6”)- 20-25%
Downhill/Freeride(7-10”)- 30-40%
Here is an easy guide to setting the sag on your bike, you will want to do this leaning against a wall or with a friend to help you.
-Wrap a zip-tie around one stanchion of your fork then sit on the bike, and lean forward like you are climbing or stand up in the case of a downhill bike. Bounce a few times so the suspension settles in to its travel, then slide the zip tie down to the dust wiper.
-Carefully step off the bike without bouncing then measure the distance between the zip tie and the dust wiper. Take this number, divide it by the amount of travel your fork has then multiply by 100, this is your sag. Add or remove air pressure until you reach the desired amount of sag.
-Sit on your bike in your usual riding position then bounce a few times so the shock settles in to its travel. Measure the distance between the shock mounts. Subtract this measurement from the static shock length.
-Divide that number by the stroke length of your shock (which is the amount of shaft that you can see sticking out when the bike is at rest), then multiply it by 100 to get you rear suspension sag. Again add or remove air pressure until the desired amount of sag is reached. In the case of a coil shock, add preload by turning the collar on the spring but do NOT exceed 5 turns from fully wound off. If more the 5 turns is needed, change to a harder spring.
