3.3: SET UP OF FORK
Tools Required: Good Quality Shock Pump.
Small Ruler
The front suspension fork fitted to your Whyte bike will be pre-set with the standard set-
tings. Before riding, you may need to adjust these setting. First is the Sag setting on the
fork. This is to ensure the forks are set-up correctly for your own body weight, so the fork
will perform as intended.
To set Sag on the front fork, you need to measure the
amount the fork compresses when you sit on the bike in the
normal riding position. See the table on the right for our
recommendation of front fork sag on your Whyte bike. To
achieve this you will need to adjust the air spring pressure
inside the fork.
Refer to the specification tables in this manual, and then to
the relevant fork manufacturers set up instructions to find
how to adjust the air spring pressure in the fork. Using a
shock pump, either add or remove air until Sag is correctly set.
Please note that for the detailed instructions for servicing and all matters relating to the
forks fitted to your Whyte bike, please refer to the manufacturers instructions.
Rebound Damping adjustment:
This adjustment fine-tunes the speed at which the wheel returns to its normal ride height
after hitting a bump. Refer to the relevant manufacturers instructions to find out how to
adjust the rebound damping. To demonstrate the effect of this function, turn the adjuster to
its slowest setting. Press down on the handlebars to compress the forks, then release the
load. The suspension recovers very slowly to its original position.
Repeat the above with the adjuster turned to the fastest setting and the difference will be
seen immediately the load is released. We recommend the optimum setting is to adjust the
re-bound damping to be as slow as possible, but not so slow that the normal ride height is
not recovered. On very rough terrain, if the bike becomes progressively lower as more
bumps are hit then the re-bound damping is set too slow. On the other hand if the bike feels
choppy and not plush then the re-bound damping is too fast. A bit of trial and error is
needed to get the exact setting.
IMPORTANT SAFETY NOTE:
Always stop riding when making adjustments of any kind to the bicycle!

Figure 7. Then firmly twist the saddle to confirm the seat-post is still securely gripped by the
lowered torque value that allows the “dropper” seat-post to function correctly.
CAUTION! When adjusting the saddle height you MUST obey the Minimum insertion
depth requirement marked on the Seat Post (7). Also consult the seat-pin manufactur-
ers instructions in conjunction with these notes.
