15. With all front-end parts of the bike installed, check again for proper 

headset tightness by engaging the front brake and rocking the front of 

the bike back and forth, looking for knocking in the headset. If needed, 

loosen the upper crown bolts, tighten the headset top cap, and repeat 

the relevant portions of step 11 to remove any play in the assembly.

AIR PRESSURE FILL PROCEDURE

1. Unthread and remove the negative air chamber cap found on the 

bottom of the spring leg.

2. Attach a high-pressure, suspension specific pump to the valve and 

using the pump’s bleed button, remove all pressure. Remove the pump.

3. Locate the positive air chamber cap at the top of the spring leg. 

AIR SPRING SETUP

The Bartlett uses MRP’s FulFill™ air spring system with independent 

positive and negative chambers. It is critical the you follow the steps 

below in order for proper suspension function.

 

Because the Bartlett is a high-performance fork and its desired 

feel is highly subjective, we recommend experimenting with different 

air pressure settings in conjunction with Ramp Control settings and air-

volume modifications (using the included Huck Pucks).

 

In testing, we’ve found that the common usable range for air 

pressure is between 90-200 PSI. A good starting point for most riders 

seems to be a positive pressure (in PSI) equal to approximately 

65-70% of body weight in pounds (lbs.). For example, a 175 lb. rider 

should start with 118 PSI in the positive chamber. Most riders like slightly 

more pressure in the negative chamber. You may inflate the negative 

chamber to as much as 10% or 10 PSI (whichever is greater) more than 

the positive chamber.

 

If you are unfamilar with lbs. (pounds) the conversion from kg. 

(kilograms) is: 

kg. x 2.2 = lbs.

Here are some examples:

RIDER WEIGHT

150 lbs. / 68 kg.

175 lbs. / 79.5 kg.

200 lbs. /91 kg.

225 lbs. / 102 kg.

POSITIVE PRESSURE

101 PSI

118 PSI

135 PSI

152 PSI

NEGATIVE PRESSURE

105 - 111 PSI

122 - 130 PSI

140 - 149 PSI

158 - 167 PSI

IMPORTANT BRAKE INFORMATION:

THE BARTLETT FORK FEATURES A POST MOUNT FOR 180mm 

ROTORS. SHOULD YOU WANT TO USE A LARGER ROTOR, MAKE 

SURE TO USE THE APPROPRIATE DISC BRAKE ADAPTOR AS 

RECOMMENDED BY YOUR BRAKE MANUFACTURER. FAILURE TO DO 

SO COULD RESULT IN SERIOUS INJURY OR DEATH.

Unthread and remove the positive air chamber cap and attach a high-

pressure suspension specific pump to the valve.

4. Fill the positive air chamber to the desired pressure. Remove the 

pump and re-install the positive air chamber cap.

5. Return to the negative air chamber; attach the pump, fill to the 

desired pressure, remove the pump, and re-install the negative air 

chamber cap.

RAMP CONTROL™ ADJUSTMENT

 

Ramp Control gives you the ability to 

adjust, on-the-fly, the air spring’s ending-stroke 

curve. Ramp Control is completely independent 

of your damper or air spring pressure settings. 

All MRP forks feature super-supple small-bump 

compliance, but with Ramp Control you can set 

your fork up to be super plush but still resist 

bottoming. Cadillac-plushness not your thing? Dial back the Ramp 

Control and up your pressure to enjoy a more linear fork that rides high 

but uses every inch of travel effectively.

HUCK PUCK (AIR VOLUME) TUNING

The Bartlett comes stock with two Huck Pucks installed. You may 

install as many as 5 total (3 additional) Huck Pucks. The installation of 

Huck Pucks reduces the volume of the positive air spring and thereby 

changes the overall spring curve. With additional Huck Pucks, the 

biggest change occurs at the end of the stroke, where it becomes 

more progressive (less susceptible to bottom-out). This change in 

performance occurs at all compression speeds, where the Ramp 

Control function mostly increases ending-stroke ramp on high-speed 

compression events.

HUCK PUCK INSTALLATION OR REMOVAL

1. Release all air pressure from the negative air spring by depressing the 

Schrader valve core on bottom of the air leg of the fork. Fully open the 

Ramp Control adjustment and repeat the same for the positive spring 

(at the top of the air leg of the fork). To ensure all air is released from 

both chambers, cycle the fork 2-3 times and depress the positive valve 

core again.

2. Use an 11mm socket to remove the lock nut on the positive spring’s 

schrader valve and allow for removal of the Ramp Control knob and 

The Ramp Control cartridge assembly is located at the top of the spring-side 

fork leg, and adjusted via a 16-position knob there. Clockwise adjustment 

of the knob will reduce the forks tendency to bottom-out on hard hits and 

increase the ending-stroke spring curve.
