DIAMOND NON BOOST TRAVEL CHANGE (diamond boost travel change guide is below)
The Diamond fork travel can be configured to 140mm, 150mm and 160mm. 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 and a step by step PDF guide that 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.

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!

The DVO Diamond comes with an integrated fender that can be used during muddy or sandy conditions. The Diamond fender kit includes the following:
• 1 x DVO Fender
• 1 x Mounting Bolt
• 2 x Snap-In Bolts
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.

Air Pressure Range: 90-170psi
Rider Weight | Air Pressure |
120-139lbs | 54-63kg | 90-100psi |
140-159lbs | 64-72kg | 100-110psi |
160-179lbs | 73-81kg | 110-125psi |

240+lbs | 109kg+ | 140-170psi |
SAG is the amount your fork compresses under your body weight (don’t forget to include your riding gear), also referred to as Rider Weight. Since this is an enduro specific fork, measure sag by mounting your bike with your riding gear on, standing up and in the ready position. The ready position is basically, knees and elbows slightly bent, bars weighted but body weight on your feet. Every rider has a different riding weight and ready position based on rider height and style.
The recommended sag is 15%-20%. Setting proper sag is the only way to find the right air pressure for your fork. Refer to the chart below to find the proper sag.
Travel | Sag in % | Sag in mm |
140mm | 15-20% | 21-28mm |
150mm | 15-20% | 23-30mm |
160mm | 15-20% | 24-32mm |
Proper position when measuring sag
Rebound Range: 20 clicks total
Rebound controls the speed at which the fork extends after compression. Rebound damping control is relative to the amount of air pressure used. Higher air pressure requires more rebound damping and lower air pressure will require less rebound damping so please adjust accordingly. Slower = More Rebound Damping Faster = Less Rebound Damping |
LOW SPEED COMPRESSION
The Diamond comes with a “Quick Range” low speed compression adjuster that has 6 clicks of adjustment. Setting “1” is wide open and recommended when descending or riding on technical terrain. When you are climbing, you can switch the LSC to “6” to give you the firmest setting and best pedaling platform. Don’t forget to change this back when you start to descend!
Low speed compressions controls the slower vertical movements such as climbing or slower paced trails and bumpy whoop sections. A good example of low speed is rolling slowly over a large rock and riding to its downside, this is where the suspension will fully compress but at a slower rate and low speed compression circuit comes into play. LSC refers to the shaft speed of the suspension and not the actual riding speed. LS compression is best controlled through a low speed oil circuit and or shim stack.
Low Speed Compression (LSC) Range: 6 clicks total
High Speed Compression (HSC) Range: 29 clicks total
Setting up your fork is one of the most important things you can do to get the most out of your suspension. Follow these base tunes and get your suspension dialed. Remember, these are starting-points. Rider ability, preference and track conditions will vary.
When setting up your compression and OTT, start from Wide-Open. Wide-Open is characterized by taking the adjuster and turning it counter-clockwise until it stops. The Compression and OTT adjustments below refers to making adjustments clockwise from the Wide-Open setting.
When setting up your rebound, start from fully closed. Starting from closed is the best way to find your perfect rebound setting. The rebound adjustment below refers to making adjustments counter-clockwise from the Fully-Closed setting.
