This service should take about 10 minutes. Always check your air pressure after servicing. The pressure should be 250-300psi when the post is fully extended.
STEP 1: SEAT CLAMP ASSEMBLY
Unthread rear clamp bolt (4) using your 5mm hex key. Remove clamp nut (1) & upper clamp (2). You can then remove your saddle & the lower clamp (3). clean assembly and put aside until you have check the air pressure at the end of this service.
TIP: Leave front clamp bolt (4) & dont adjust it. When you reinstall the seat, torque the rear clamp bolt to 8Nm (70 in-lbs) and your seat angle will remain correct.
STEP 2: VALVE CAP OR COVER
Once seat clamp assembly is removed, there will be either a rubber cover (5) or metal valve cap (5). Either can be removed by hand or with needle nose pliers to expose the cartridge lock ring (6).
STEP 3: REMOVE CARTRIDGE LOCKRING
Using your needle-nose pliers, unthread and remove the cartridge lockring (6).
Holding the post upside down, unscrew the green actuator (16) from the lower tube (12) using your wrench.
Once free of the lower tube (12), you can slide the lower tube up the upper tube (7) to expose the cartridge (14) & actuator lock bolts (17).
Alternate route: With the cartridge lockring (6) off, the cartridge & actuator (16) can be pulled out from the upper & lower tube assembly. The upper & lower tube assembly can then be set aside. Once the actuator has been removed (step 5) you can skip step 6 below.
STEP 5: REMOVE ACTUATOR FROM CARTRIDGE
Remove the 2 actuator lock bolts (17) using your 2mm hex key. You can then slide the actuator (16) & foam washer off the bottom of the cartridge (14).
STEP 6: REMOVE CARTRIDGE
Now that both the cartridge lockring (6) & actuator (16) have been removed, the cartridge can be pulled out the bottom of the dropper.
The cartridge push rod is held into the cartridge (14) by the actuator (16). When the actuator is off, the push rod can fall out of the cartridge. Be careful not to drop the push rod from the new cartridge before or during assembly.
STEP 7: CARTRIDGE WASHER
The cartridge washer (13) is included with your replacement cartridge (14). Before installing the cartridge, Make sure this washer is sitting correctly in its seat around the air valve at the top of the cartridge, as pictured below. This washer will not only stop grit and moisture but it also stops the cartridge from spinning as you tighten the cartridge lockring (6). If you find your cartridge is spinning with the lockring, it may be because this ring is damaged or not present.
STEP 8: INSTALL ACTUATOR
Slide foam washer and actuator (16) back onto the bottom of the cartridge (14). Thread the actuator lock bolts (17) into the cartridge with your 2mm hex key & snug down. Do not over tighten as you risk stripping the small 2mm tool interface.
STEP 9: INSTALL CARTRIDGE
Slide cartridge (14), air valve first, back up through the bottom of the lower tube (12). Guide the cartridge air valve up through the hole in the upper tube (7). Thread actuator (16) into lower tube using your wrench.
STEP 10: CARTRIDGE LOCKRING & PRESSURE CHECK
Install & tighten cartridge lockring (6) using your needle nose pliers. You can now safety actuate the post to max extension. Attach Shock pump to valve. Inflate post to 250-300psi in the fully extended position. Thread valve cap (5) back down onto the valve.
Note: These cartridges are high pressure in a small volume. The pressure loss during removal of the pump & equalization of the pump upon installation will produce a lower pressure reading than what was originally in the cartridge. This pressure loss can be as much as 50psi depending on the pump size and quality.
STEP 11: SEAT CLAMP ASSEMBLY
Place lower clamp (3) into the cradle of the upper tube (7). Make sure the arrow is pointing forward. Place your saddle on the lower clamp. Holding your saddle, slide the upper clamp (2), arrow forward, under the front clamp nut (1) and place it on top of the saddle rails. You can then drop the rear clamp nut into its seat at the back of the upper clamp. Thread rear clamp bolt (4) into nut and tighten to 8Nm.
Congratulations, you have now successfully completed the V2 dropper cartridge replacement service.
