What to Compare Before Buying

  • Headset size: Check that the 1-1/8 and 44 mm fit matches your frame and fork setup.
  • Fork tube diameter: The stated 28.6 mm fit matters if you are matching the expander plug and nut to your fork.
  • Fork type: The wording mentions carbon fibre forks and mountain suspension forks, so confirm your fork matches the intended setup.
  • Threadless build: Make sure your bike uses a threadless headset arrangement.

Compatible With the Right Fork Setup

This headset is presented for a threadless MTB build with a 1-1/8 size and 44 mm fit. The expander plug and nut are stated to suit a 28.6 mm front fork tube, so that measurement is the main compatibility check.

If your bike uses a different headset size, a different fork tube diameter, or a non-threadless arrangement, a different version is likely needed.

Before You Decide

Confirm the 1-1/8, 44 mm headset size against your frame and fork. Check the 28.6 mm fork tube fit for the expander plug and nut, and make sure your bike uses a threadless setup. The black finish and double-sealed steel bearings are part of the stated configuration.
