Safety

WARNING
Properly tighten hardware
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
Reapply thread locker
All reused-fasteners with pre-applied threadlocker must be cleaned with isopropyl alcohol and have new threadlocker applied before re-assembly. If threadlocker is not  applied, the fasteners may loosen which could damage the bicycle and result in injury to the rider.

Adjust the geometry

Flip the lower shock mount Mino nut and spacer to change the bike’s geometry to fit your riding style or the terrain.

Steeper head tube angle

Mino nut and spacer in the high position

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

Slacker head tube angle

Mino nut and spacer in the low position

• Pushes the head tube angle back 0.5° and pushes out the front fork for slower steering that is more stable at high speed

Suspension

The first step in suspension setup is to determine the sag. All other settings should be adjusted after determining the sag.
Refer to the suspension setup card included with your bike or the suspension calculator at Trekbikes.com/suspension-calculator.
For recommended rebound settings refer to the suspension calculator at Trekbikes.com/suspension-calculator.
