Safety

WARNING
Tighten hardware properly
Always tighten hardware to the specified torque.
Over-tightening hardware could deform or break the hardware or components. Under-tightening hardware could cause hardware or components to become loose.
Either situation could damage the bicycle and result in injury to the rider.
WARNING
Re-apply threadlocker
All reused-fasteners with a pre-applied threadlocker must be cleaned with isopropyl alcohol and have new threadlocker applied before re-assembly. If a threadlocker is not applied, the fasteners may loosen, which could damage the bicycle and result in injury  to the rider.

Dérailleur hanger

Tools

• 8 mm hex tool
• Torque wrench (left-hand thread) with 8 mm hex bit

WARNING
Do not apply grease to the derailleur hanger or bolt. Only apply grease to the thru axle.
This bicycle frame is designed to use a Universal Derailleur Hanger (UDH).
NOTICE: The thru axle must be compatible with a UDH and must be M12x1.0 with a 12.7 mm thread.
NOTICE: The washer is frame-specific. Install only the washer compatible with your frame.
NOTICE: Do not over-tighten. Over-tightening the bolt could cause the hanger to break.
For additional information about the UDH, refer to the SRAM user manual at www.sram.com.

Active Braking Pivot (ABP)

Rocker pivot and seat stay

Adjust the geometry

Flip the Mino link in the seatstay pivot to change the bike’s geometry to fit your riding style or the terrain.
Notice: If using a 29″ wheel up front and a 27.5″ wheel in the back, the minolink must be in the high position.
Steeper head tube angle

• Pulls in the front fork for quicker steering
• Raises the bottom bracket for improved climbing

Slacker head tube angle

• Pushes the head tube angle back 0.5° and pushes out the front fork for slower steering that is more stable at high speed
• Lowers the bottom bracket up to 9 mm for more stability

Tools

• 5 mm hex tool

1. With the bike on the ground, loosen and remove one Mino Link chip.

2. Loosen and remove the other Mino Link chip.

3. Position the bike:
   Mino Link high : Lift the bike by the seat tube. This will pull the rear triangle up and forward.
   Mino Link low : With the chips removed, gravity will pull the rear triangle down and back.

4. Place one Mino Link chip into the desired position. Slightly tighten the Mino Link bolt.

5. Install the other Mino Link chip into the same position. Slightly tighten the Mino Link bolt.

6. Torque both Mino Link bolts to 17Nm.
