Diamond BOOST Travel Change
This is a guide to changing the travel on your BOOST Diamond. If you have a NON-BOOST Diamond, you can find the guide in the lower tab.
The Diamond Boost 27.5 version has a minimum travel of 140mm’s, and a max travel of 170mm’s. The Diamond Boost 29 version has a minimum travel of 130mm’s and a max travel of 160mm’s. DO NOT go outside of these travel ranges!
Travel adjustment is done by changing the spacers inside the air cartridge. This task should be performed by an Authorized DVO Suspension service center or a qualified suspension mechanic. Below is a video that will show you how to perform the travel adjust.
WARNING! PLEASE MAKE SURE THAT YOU RELEASE ALL THE AIR OUT OF THE AIR CARTRIDGE BEFORE PERFORMING THIS TASK. SERIOUS INJURY MAY OCCUR IF YOU DO NOT REMOVE ALL AIR FIRST. YOU HAVE BEEN WARNED!

Crash & Visual Inspection
After a crash, do not ride your bicycle, if any one of the following test criteria is not passed! Riding your bike without eliminating any defect or carrying out the necessary adjustments can result in an accident, serious injury or even death.
- After a crash, Do you notice any cracks, dents, bent or tarnished parts of your suspension fork or any other part of your bicycle? If so, please contact a trained and qualified bicycle mechanic to check your fork and/or complete bike.
- Can you notice any oil leaking out of your fork? Check hidden areas like behind the fork guard under the crown and main seals. If so, please consult a trained and qualified bicycle mechanic to check your fork or bike.
- Make sure your wheels are perfectly centered in order to avoid any contact with suspension fork or brake system. Check and see if your handlebars are aligned with the front wheel
- If the wheel is not aligned with your handlebars, please inspect the fork for damage and re-adjust fork in the clamps. Refer to fork installation guide for proper set-up and torque specs.

Jade X Full Service
Below is a link to the full service/bleed guide for the Jade X Coil Shock.
Air Pressure
Setting the air pressure in the DVO Diamond is setting the spring rate for your fork. This is what is going to make the fork firmer or softer. Below is a base setting chart for air pressure to get you started. Set your pressure to the recommended PSI then check your SAG point. If you are sagging too much, add some air pressure, if you’re sagging too little, remove air pressure.
Proper Set Up
The Diamond uses an external negative spring adjust (OTT) to tune the beginning of the travel (sensitivity of the fork). Once you get into the mid-stroke of the fork, the air spring (air pressure) is active. This controls your mid-stroke support and your bottom out. In simpler terms, set your air pressure for your mid-stroke and bottom out then set your OTT to fine tune how it feels off the top.
How do I know how much OTT is right for my air pressure?
Lighter riders (lower air pressure) will use less OTT. (less sensitive) Heavier riders will need more OTT (more sensitive). The reason for this is because the OTT is there to counter-act the forces of a higher air pressure so you don’t loose small bump sensitivity. When you are using a lower air pressure, you don’t need as much to counter-act the air pressure. If you run too much OTT with a light air pressure, the fork will suck itself down and you will loose travel.

To access the air valve you must remove the air spring cap. Attach your shock pump securely and inflate the air spring to the recommended air pressure. After you have added the proper amount of air pressure remember to securely replace the air spring cap so that no dirt or moisture can get inside.
