How to Install your Saddle onto this Carbon Seatpost

Step 1: Loosen the Clamp Bolts

Use a hex key to loosen the bolts on the seatpost clamp. Do not remove them completely; just loosen them enough to release the top clamp.

Step 2: Remove the Upper Clamp Piece

Carefully lift the upper clamp piece off the seatpost. This will allow space to position the saddle rails.

Step 3: Prepare the Saddle Rails

Align the saddle rails with the lower clamp section on the seatpost. Ensure that the rails sit securely in the designated grooves.

Step 4: Position the Upper Clamp Piece

Place the upper clamp piece back over the saddle rails. Make sure the rails are evenly positioned before proceeding.

Step 5: Insert and Lightly Tighten the Bolts

Reinsert the bolts and tighten them slightly with a hex key. Do not fully tighten yet; you may need to adjust the saddle angle.

Step 6: Adjust and Secure the Saddle

Adjust the saddle position to your preferred angle. Once positioned correctly, tighten the bolts evenly to the recommended torque setting (≤ 5.1 NM). Ensure both sides are tightened evenly to prevent damage.
