CAUTION: All Chubby fork bolts should be tightened to the proper torque when servicing your fork. Failure to torque all bolts properly can result in failure during use and severe injury.

WARNING: Make sure preload adjuster is installed fully. Failure to do so could lead to fork bottoming out and serious injury.

Preload

 

Preload is the amount of load placed on a spring to increase the spring rate in the initial part of the travel. All of our Chubby forks

 

feature adjustable preload. Preload is used to help achieve the proper amount of suspension sag for your bike or fork.

 

Suspension sag is the amount a shock compresses under the weight of the rider. All suspension systems should exhibit some amount of

 

suspensionsag. Noleenforksshouldallbesetupproperlywithacertainamountofsag. Theoptimumsagamountforallofour frontsuspension

 

systems is 20% of the total wheel travel. For example:

Adjusting Preload

Our Chubby LT has 125mm / 5 in. of travel. To calculate the optimum sag for this fork, multiply 125mm by .2. The answer

gives you a suggested sag , which for the Chubby is 25mm / 1 in.

2.Measure the distance between a point on the lower leg of the fork (bottom edge of the fork boot, for example) and a point on the upper part of the fork (The bottom of the lower triple crown) with no weight on the bike.

3.Then measure from the same two points with a rider on the bike. (You will need some help with this). The difference between the two measurements is the amount of suspension sag.

4.To increase preload on the Chubby, turn preload adjuster caps clockwise. To decrease the preload on the Chubby, turn preload adjuster caps counterclockwise.

Damping is the action of controlling the rate at which a shock compresses and extends.Therateat whicha springcompresses andextends can be controlled by a number of ways. The Chubby forks use an air damper in each leg to control the rate of rebound and compression.

The first type of damping is rebound damping. Rebound damping controls the rate at which the spring extends back to its optimum sag length.

The compression and rebound damping in our Chubby forks are nonadjustable. The air dampers provide ample rebound and com- pression damping for many different riders.
