Hi. I have a Scott Genius plus 2017

According to CraneCreek the headset is a zs44/zs55.

The closest I can find on the Superstar site is ec44/zs56.

Is this right? Is zs56 close enough to zs55?

What were you testing for? Did we pass?

Apparently my ability to click on the post button accurately. I missed it a couple of times this afternoon.

Works components do some that would fit, eg: https://www.workscomponents.co.uk/10-degree-ec44-zs55-angle-headset—to-suit-tapered-steerer-tube-409-p.asp

You can get 1, 1.5 and 2 deg headsets from them.

55 refers to the diameter. Zs56 would be 1mm too wide to fit and tolerances are tight on headsets.

Ec means external cup so you would gain some stack height under your stem but if you have spacers already you can just swap them out.

Much thanks
