Why Flip the Chip?

The Epic 8 and Epic 8 EVO come with different geometry out of the box:

Epic 8: Ships with the flip chip in the high position.
Epic 8 EVO: Ships in the low position.

Specialized says that switching from low to high:

Raises the bottom bracket by 5mm
Steepens the head tube angle by 0.5°

I run my Epic 8 EVO in the high position after installing 120/120mm RockShox Flight Attendant to keep pedal strikes down, increase efficiency, and improve handling on tight, punchy courses.

Tools You’ll Need

4mm and 6mm hex wrenches
Digital torque wrench (highly recommended)
Microfiber towel
High-quality grease
Loctite

Step 1: Remove the Shock

Get the bike into a stand and remove the rear wheel so there’s no weight on the rear triangle.

Microfiber towel protecting frame — I like to tuck a microfiber towel behind the shock extension to protect the frame while working.

Loosen and remove:

Front shock mounting bolt
- 4mm hex
- Torque: 6 Nm
Rear shock mounting bolt
- 6mm hex
- Torque: 20 Nm

⚠️ Carefully track the washers:

Front mount: 2 washers per side
Rear mount: 1 washer on drive side

Step 2: Flip the Chip

Once the shock is off, you’ll see the flip chip insert at the bottom of the shock yoke.

Bottom view of flip chip positions — High vs. Low position. It’s a simple rotation of the chip.

Rotate the chip 180° to change the position:

Low → High: Raises BB, steepens head angle
High → Low: Lowers BB, slackens front end

Make sure the chip is fully seated before reinstalling the shock.

Step 3: Clean, Grease & Reinstall

Cleaning the front shock axle — Clean the axle and threads with a microfiber towel.

Before reinstalling:

Clean the front shock mounting axle
Reapply high-quality grease to:
- Front axle
- Interface between front bolt head and axle
- Rear bolt’s non-threaded shaft
Apply a drop of Loctite to the front bolt

Then reinstall the bolts:
