FACT 11m carbon frame on S-Works, Pro, Expert, and Comp Carbon models. M5 premium aluminum on Comp Alloy and Base Alloy models.

Frame Geometry

The adjustable headset and Horst pivot flip chips enable a steeper/slacker head tube angle or seat tube angle, as well as affect the other geometry measurements. Note: The Base Alloy model is not compatible with the adjustable headset cups.

Horst Pivot Flip Chip

All models are assembled with the flip chip in the high position. Switching to the low position lowers the bottom bracket height by approximately 7 mm and slackens the head tube angle by approximately 0.5 degrees.

To adjust the Horst pivot flip chip:

  1. Remove the Horst pivot bolt from the frame (A in image below)
  2. Remove all four flip chips (B)



  3. Align the Horst pivot spacer in the slot to either the low (A) or high (B) position as shown below. Ensure that both parts of the flip chip are aligned in the same direction.

  4. Reinstall the flip chips in the desired high or low position. Make sure they are fully seated and aligned with the chain stay protector before you tighten the bolt.
  5. Torque the pivot bolt to 10 Nm / 90 in-ft.

Adjustable Headset

The head tube angle can be adjusted with the adjustable headset cup. The bike is shipped with the zero degree offset cup installed (A). The +/- 1 degree headset cup (B) is in the small parts box.

The headset uses standard bearings, with a 1 1/8" upper bearing and a 1 1/2" lower bearing.

Note: The Base Alloy model is not compatible with the adjustable headset cups.

To change the headset cups:

 Click here to expand...
  1. Loosen the stem bolts (A) that attach the stem to the fork steerer
  2. Loosen and remove the top cap bolt (B) and cap
  3. Remove the stem (C) and spacers from the fork steerer (D) and remove the fork from the frame


  4. Remove the zero offset cup from the head tube and replace with the +/- 1 degree headset cup. The offset is etched onto the headset cup. Orient the offset you prefer toward the front of the bike. 
    *Note, you do not need to change the bottom headset cup as it works with all upper headset cup options


  5. Clean and grease the headset parts and bearings before installing into the frame (A: headset cover, B: compression ring, C: upper bearing, D: adjustable headset cup)


  6. Reassemble the stem assembly:
    1. Slide the fork steerer (D) through the head tube and headset parts 
    2. Install the spacers and stem (C) onto the fork steerer 
    3. Install the top cap and thread the compression bolt (B) into the star nut in the fork. Tighten the bolt until all parts are snug and settled. The stem should rotate freely, but there should be no fore/aft play in the system
    4. Pull the front brake and rock the bike back and forth to ensure everything is well seated
    5. Re-tighten the headset compression bolt if needed
    6. Torque stem bolts (A) to 5 Nm or 44 in-lbf
