Set Up Of Fork; Suspension Tuning Log - Whyte 27C Works Supplementary Service Manual

3.3: SET UP OF FORK

Tools Required:
The front suspension fork fitted to your Whyte bike will be pre-set with the standard settings. 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 rele-
vant 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 mat-
ters 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 re-
bound 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.
