Fork Installation
Fork Installation
Warning
DVO Suspension strongly recommends that your fork be installed by a trained and qualified bicycle mechanic. Special knowledge and tools are essential to properly install DVO Suspension forks. Common mechanical knowledge may not be sufficient to install a DVO Suspension fork. If you intend on installing the fork by yourself, the whole job needs to be inspected by a trained and qualified bicycle mechanic. Please note, that improperly installed forks are extremely dangerous and cause damage to the product, serious injury or even death. All DVO Suspension forks come with a threadless steer tube. Do not add a thread to it! DVO Suspension fork steer tubes are for one-time press fit only which cannot be removed. Do not try to replace the steer tube with a threaded steer tube. This will void the warranty of your fork and result in a failure of the product or cause serious injuries or even death to the rider. - If changing a fork on an existing bicycle, remove the front wheel and brake from your fork. After, remove the headset crown race from the fork.
- Using a headset race installer, install the headset crown race on new steer tube. Make sure it is firmly against the fork crown leaving no space between the crown race and the fork crown. (Refer to your headset manufacturer’s instructions to make sure the crown race is properly installed)Measure the steer tube length of existing fork and transfer this measurement to your new DVO Diamond steer tube. If you do not have an existing fork to measure you must install the fork into the bicycles head tube with the complete headset, stem and spacers. (Refer to your stem manufacturer’s instructions to be sure there will be enough clamping surface for the stem.) In this case you may need to cut your steer tube slightly shorter (3mm) to allow enough clamping surface so that the stem cap bolt can pull up on the steer tube, ensuring a snug and proper fit.
- If it is necessary to cut the steer tube, MEASURE TWICE CUT ONCE. It is recommended that a cutting guide be used when cutting the steer tube.
- Install the star nut into the steer tube using a star nut installation tool to the proper depth.
- Install the DVO Diamond fork into the frame head tube. Tighten the star nut bolt so that there is no play or drag in the headset when turning the steer tube.
- Properly align the stem and handlebars then torque the stem clamping bolts to the stem manufacturer’s specifications.
- Install the front brake according to the manufacturer’s instructions and make sure you adjust the brake pads properly. Ensure that brake line length is the correct length to not effect steering or compression and extension of the fork. NOTE: Rotor size must be between 160mm-203mm
- Install the front brake hose through the cable guide. Make sure the hose is routed on the inside of the leg. Use a 2mm allen key and torque to 3nm to secure hose and cable guide.
Wheel & Axle Installation
Wheel Installation
- Insert the front wheel back onto the bike. Make sure the hub fits into the drop outs, then insert the thru axle from the non-disc side. Slide the axle until it makes contact with the threads of the axle bolt on the disc side.
- Rotate the axle lever clockwise until there is a small gap between the lever bolt and drop out on the non-disc side. The axle bolt should sit flush inside the grooves of the lower. If the axle bolt is not sitting inside the grooves release tension on the axle and line up the axle bolt so that you can lightly press it into the grooves. The axle bolt will secure itself when you tighten the axle again.
 Axle Bolt Open |
 Incorrect Position |
 Correct Position |
- To secure the axle, position the lever in the open position. When you flip the lever half way you should feel resistance and the lever bolt should be touching the drop out. Flip the lever to the closed position by hand strength only. The lever should feel very secure. DO NOT USE ANY TOOLS FOR LEVERAGE.
 Open |
 Resistance Starts |
 Closed |
- If there is too much or too little resistance adjust the axle bolt on the disc side. Unthread the axle 3 full turns then push the axle to the drive side. This will push the axle bolt out so you can adjust it. If the axle has too much tension then turn the axle bolt counter clock wise. If the axle did not have enough tension then turn the axle bolt clock wise. Rotate axle lever clockwise again and secure lever until there is proper tension in the closed position.
- Remove bike from stand. With the front brake on, lightly rock the bike back and forth to ensure the headset preload is at the appropriate torque value. THERE SHOULD BE NO PLAY IN THE HEADSET.
Fender Installation
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
| Using a 3mm allen key (ball end recommended), carefully thread in the 2 snap-in bolts into the lower holes on the rear of the arch and torque to 3Nm. Once these have been installed these bolts do not have to be removed. *Be careful to not scratch the stanchions during installation. |  |
| Line up the fender with the snap-in bolts and press down until secure. Fender will “snap” into place. BE SURE TO APPLY PRESSURE OVER THE MOUNT BOLT AND NOT THE TAIL OF THE FENDER. |  |
| Using a 3mm allen key, insert the fender mount bolt into the center of the arch and torque to 3Nm. There should be no play between the fender and the arch. |  |
| FENDER REMOVAL Unthread the center mount bolt first. Then pull the fender upwards to release it from the lower snap-in bolts. DO NOT PULL UP on the tail of the fender. The snap-in bolts will stay threaded into the arch. |

Air Pressure Guide
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.
View one of the lower tabs to learn more about your OTT
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.

Sag
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 |

OTT “OFF THE TOP” Guide
 |
The Off-The-Top (OTT) feature is an exclusive DVO Suspension design. It allows the rider to adjust the initial sensitivity of the fork. Typically, a firm feeling fork (higher air pressure) will have poor or no small bump sensitivity. DVO has solved this problem with OTT. Now a firm set-up can also have amazing small bump sensitivity. This is accomplished by externally adjusting the preload on the negative springs. Increasing (rotate clockwise) the OTT will make the fork more sensitive (softer) at the beginning stroke. Decreasing (rotate counter-clockwise) the OTT will make the fork less sensitive (firmer). The OTT feature will not change the middle or ending stroke of your fork.
YOU WILL NEED A 5MM ALLEN KEY TO ADJUST THE OTT FEATURE. OTT Range: 14 full rotations total (6 clicks per rotation) Clockwise = Increase Sensitivity |
Rebound and Compression
| 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 |
- Why do you need rebound?
Rebound is how fast the suspension returns after it is compressed. It needs to be slow enough so the rider isn’t bucked off their bike but then fast enough so that in a series or impacts, the wheel returns in time to absorb the next impact - What happens if your rebound is too fast?
If rebound is too fast, your wheel will fall into more holes, instead of skipping over the top of them. Handling will feel twitchy and hard to control, it will be easier to be thrown out of control on jumps and landings. - What happens if your rebound is too slow?
If rebound is set too slow it will pack on successive hits because the fork cannot extend fast enough keeping you in the mid stroke. This will result in the wheel going deeper into the travel on every hit and riding towards the end stroke.
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
- Why do you need Low Speed Compression?
Low speed compression affects the suspensions performance when the shaft is moving up and down at slow speeds. Low Speed affects small bump performance and controls dive under breaking. - What happens if you have too much Low Speed Compression?
Too much Low Speed Compression will result in harshness over small bumps and traction will be reduced. Turning performance may also suffer because the suspension will ride to high in its travel. Ride may become harsh. - What happens if you don’t have enough Low Speed Compression?
Not enough Low Speed Compression will result in the front end diving to quickly under braking. The suspension will have a mushy feeling and may bottom out to easily.
HIGH SPEED COMPRESSION
High Speed Compression controls the damping force under faster suspension movements regardless of the rider’s speed. HSC comes into effect on fast, rough, technical trails, g-outs and hard landings. If you find yourself easily going through the travel then 1st make sure your sag is correct then adjust your HSC accordingly.
High Speed Compression (HSC) Range: 29 clicks total
- Why do you need High Speed Compression?
High Speed Compression damping affects the suspension when the shaft is moving up and down at high speeds. High Speed Compression helps with large impacts or sharp/sudden impacts. High Speed Compression can be used to reduce bottom. - What happens if you have too much High Speed Compression?
Too much High Speed Compression may result in the fork not being able to reach full travel, and or spiking on large impacts. - What happens if you don’t have enough High Speed Compression?
If you don’t have enough High Speed Compression, The fork will blow through it’s travel to easily on jump faces, and will bottom out to easily on large impacts.
Base Tune
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.
