Works Components EC44/ZS56 1.0 Degree Angle Headset

The Works Components angle headset makes it possible to change the head angle of any mountain bike that uses ZS44/ZS56 cups. The only catch is, in order to have room for the additional angle, a ZS44 will become an EC44, which also increases stack height by 15mm. If you have 15mm headset spacers to spare, this angleset will work without the need for a longer fork steerer.

Use of this headset requires measuring your head tube length to select the correct headset. If your headtube is between sizes, it it advised to size up to the larger size. 


    • Upper cup is external (EC) - will fit frames using ZS44 (ZS) upper headcup as standard
    • To suit standard 1 1/8" to 1.5" Tapered steerer tube forks. (28.6 - 39.79)
    • Insertion depth: 9mm Upper, 16mm Lower.
    • Proudly machined in the UK from 6082 T6, Black Anodize finish
    • Headset comes complete with top-cap (star-nut included), bearings and crown race - all parts required for fitment

      Thank you for purchasing a product from Works Components.
      The Works Components Angle Headset is installed in much the same way as a ‘normal’ headset; please ensure you have the correct tools to hand for installation. (headset press, Allen keys, crown race remover)  
      Installation Order: 
      1. Upper bearing cover
      2. Bearing compression ring.
      3. 41mm OD AC bearing (Upper and Lower).
      4. Head cup (Upper and Lower).
      5. Lower bearing sealing washer (Inbuilt into the tapered crown race).
      6. Fork crown race.

      Liberally apply grease beneath the crown race and upper bearing cover to ensure bearing longevity – Jet-washing is not advisable and will force water past seals and remove grease.
      It is essential that the Works Components cups are installed with correct orientation. If you install the top head-cup with the offset towards the rider (sitting on the bike) you must install the bottom cup in the opposite manner, this will ‘slacken’ the bikes head-angle. If you reverse the orientation you will ‘steepen’ the bikes head angle.

      It is our recommendation that you install the cups one at a time starting with the top cup:
      • Set the top cup in the frame – Tie string around the seat-post and pull taught towards you or use a large set-square: Align along the 2 machined grooves in the cup and push the cup into place firmly by hand, stand back and re-observe the cups position to ensure correct placement.
      • Using the correct tools then install the cupper cup making sure it is fully inserted, a little grease will help. – If your previous headset’s insertion depth was shallower you may notice the headset requires more force to push fully home.
      • Line up and mark the lower cup using a set square or similar to ensure you have a straight line from the upper cup – When you are happy the cup is aligned correctly install in the same manner.
