Color Coding

The color coding in this manual provides a quick way of understanding the action that will be performed in each step of the installation. Refer to this chart for more information about how each color is used.

Cassette Installation

1. Apply grease to the driver body threads.
2. Install the cassette onto the driver body until it is fully seated with the splines engaged.
3. Tighten the cassette to 40 N·m.

NOTICE
Cassette lockring tool splines must fully engage the cassette lockring or locktube (XD). Splines must be between 7 and 8 mm in length for XD cassettes.

DUB™ BSA Bottom Bracket Installation

1. Apply grease that is safe for the bottom bracket frame material.
2. After confirming the five-way dimensions of the bottom bracket shell, select the corresponding BB part number.

DUB™ Bottom Bracket Installation

1. Apply grease that is safe for the bottom bracket frame material.
2. After confirming the five-way dimensions of the bottom bracket shell, select the corresponding BB part number.

1. Remove the left side cup from the center tube.
2. Remove the right side spacer from the right side cup.

NOTICE
Make sure the right spacer is removed before installing the cups. Failure to remove the spacer will damage the bearings.

1. Use a bottom bracket bearing press tool or a headset press to install the left side cup into the non-drive side of the frame.
2. Install the right side cup and center tube bearing cup into the drive side of the frame.

NOTICE
When pressing in, be sure to check that the boot is properly aligned to the left BB. Failure to correct it will result in damage to the boot.

1. Install the spacers.

1. Apply grease to the spindle.
2. Tighten the crank arm bolt to 54 N·m.
3. Use a rubber or plastic mallet to tap the drive side crank arm until it is fully seated.

1. Turn the preload adjuster in the + direction until it stops or makes contact with the bearing shield.
2. Tighten the bolt until the adjuster edges touch.

NOTICE
Do not overtighten the preload adjuster as this could damage the bearing. Do not overtighten the bolt. It is okay if there is a gap in the adjuster, as long as the top edges touch.

Check the crankset for play by rocking the crank arms back and forth.

If there is play in the crankset, remove the crank arms and apply additional grease to the spindle. Turn the preload adjuster in the opposite direction of the + sign until it stops. Repeat the installation procedure until play is eliminated.

SRAM® Battery Installation

NOTICE
Do not discard the derailleur battery block (A) or the battery cover (B).

Insert the fully charged SRAM battery into the derailleur and close the battery latch. When installed correctly, the latch will snap into place.

System Pairing

1. Press and hold the AXS button until the green LED blinks slowly, then release.
2. Press and hold the AXS button on the controller until the green LED blinks quickly, then release.
3. Press and release the AXS button on the rear derailleur to end the pairing session, or wait 30 seconds for the pairing session to time out. The green LED will stop blinking.

AXS™ Button Shifting

Press and release the AXS™ button on the rear derailleur once to move the derailleur outboard one position, or twice quickly to move inboard one position.

Rear Derailleur Installation

NOTICE
Do not apply grease to the mounting bolt or derailleur hanger threads.

Push the B-adjust washer forward when installing the derailleur. Make sure there is no gap between the B-Adjust washer and the derailleur hanger. A gap can cause poor shifting performance.

1. Shift the derailleur outboard to the smallest cog.
2. Install the rear derailleur onto the derailleur hanger and tighten the derailleur bolt.

1. Wrap the chain around the chainring and largest cassette cog.
2. For full suspension bicycles, add one inner link and one outer link where the chain starts to overlap. For hardtail bicycles, add two inner links and two outer links where the chain starts to overlap.
3. Use a chain breaker tool to break the chain at the inner link.

1. Place the chain onto the smallest cassette cog.
2. Rotate the derailleur cage forward and press the Cage Lock lock button to lock the derailleur in the extended position.
3. Route the chain through the derailleur pulleys. Make sure to route the chain below the tab in the cage.

PINCH HAZARD
The derailleur is spring loaded and will return from the Cage Lock position rapidly. Keep fingers clear of pinch points.

Pull each end of the chain together and install the PowerLock. Press the PowerLock connector links together.

NOTICE
The arrow must point in the direction of chain travel before locking the PowerLock into place. Once locked, the PowerLock cannot be disconnected.

Chain Gap Adjustment with Gauge

1. Shift the rear derailleur inboard to the largest cog.
2. Install the chain gap adjustment gauge onto the upper pulley.
3. To make an adjustment, rotate the derailleur clockwise around the B-Adjust washer to relieve tension on the B-Adjust screw. Turn the B-Adjust screw, then release the derailleur.
4. Reinstall the gauge to check the adjustment. Repeat this procedure until the cog aligns with the gauge.

Chain Gap Adjustment without Gauge

1. Shift the chain into the 2nd largest cassette cog.
2. The gap between the tallest teeth of the largest cassette cog and the upper pulley must be 5 mm.
3. To make an adjustment, rotate the derailleur clockwise around the B-Adjust washer to relieve tension on the B-Adjust screw. Turn the B-Adjust screw, then release the derailleur.
4. Reinstall the gauge to check the adjustment. Repeat this procedure until the cog aligns with the gauge..

Rear Derailleur Adjustments

1. Align the upper pulley with the center of the 2nd-largest cog by adjusting the rear derailleur:
2. Press and hold the controller AXS button while pressing the paddle. Press downward on the paddle to adjust the derailleur inboard, and press upward on the paddle to adjust the derailleur outboard.
3. The rear derailleur may not appear to move. Watch for the derailleur LED to flash to confirm the derailleur executed the command.

1. Shift the rear derailleur inboard to the largest cog.
2. Adjust the low limit screw (L) so that it lightly contacts the outer link of the derailleur, then back the screw out a 1/4 turn.
3. Shift the rear derailleur outboard to the smallest cog.
4. Adjust the high limit screw (H) until it lightly touches the inner link of the rear derailleur.

AXS Controller Installation

1. Apply friction paste to the inner clamping surface when installing on carbon fiber handlebars.

CRASH HAZARD
Failure to apply friction paste may lead to the clamp slipping which may cause the rider to crash, resulting in serious injury or death.
