Setup, tuning and maintenance of your
Spinner Suspension Fork
Congratulations on getting a bike with Spinner suspension. To ensure the best performance and
longest service life from your Spinner suspension fork, please read and carefully follow these setup,
tuning and maintenance instructions.
CAUTION!
All Spinner products must be installed by a qualified bicycle mechanic using appropriate professional
tools. Spinner assumes no liability for products which are improperly installed.
WARNING!
Failure to follow these instructions can result in component failure. Component failure can lead
to loss of control of the bicycle and result in serious personal injury or death.
Spinner suspension forks should be tuned to your weight, riding style and riding conditions. We
recommend that you ask your dealer to set the suspension for you before your first ride. Thereafter,
follow these instructions to fine-tune your suspension to meet your needs.
1. Before you start
Identify the features: with Dial-up, or with Preload; with or without Lockout.
2. Setup and tuning of Spinner Coil Shock Forks with Preload feature
The Preload feature allows you to tune the initial sag, or static compression, of your fork, and then use
that as the base line when tuning for a stiffer or softer ride. Setting up and tuning your Spinner Coil
Shock Fork with Preload is done in the following sequence:
a. Set the Sag: Correct sag is directly related to your weight, and is the amount the suspension
travels when you sit on the bike in the riding position. The rule of thumb is that sag should be 15 to 30
percent of total suspension movement; but check with your dealer or bike manufacturer for specific sag
recommendations for your bike’s suspension geometry; then:
1) Measure and write down the distance from the front axle to the top of one fork leg.
2) Get on the bike, in riding position, and have a friend measure and write down the distance from
the front axle to the top of the same fork leg with your full weight on the bike.
3) The difference between these two measurements is the sag. If the difference between the
measurements is more than the dealer’s or manufacturer’s recommendation,
turn the Preload Adjusting Knob clockwise one click at a time until you achieve
the recommended sag. If the difference is less than the dealer’s or
manufacturer’s recommendation, turn the Preload Adjusting Knob
counterclockwise one click at a time until you achieve the recommended sag.
4) Now, turn the Preload Adjusting Knob counterclockwise, carefully counting the
number of clicks, until the knob won’t turn any further. Write down the number
of clicks from the correct sag setting to zero. You’ll want to refer to that often in
the future, because it’s the starting point for spring rate adjustments.
5) Finally, turn the Preload Adjusting Knob clockwise the exact number of clicks that you turned it
from your correct sag setting.
