Please can you give the spanner size to fit this item.

These Brompton headsets require a 36mm spanner to fit them.

What Is The Crown Race Dimesion On These 9/8 Headsets?
24 Apr 2014
I have a early 90s trek 830 that I'd like to change the headset on .. it's the 9/8th size and I think the crown races is 27.0 .. but you don't list this dimension for most of these head sets which is surprising. Not sure how you'd buy one wihtout knowing that. Pls advise.

This headset and a few others I measured have 29.8mm crown races which is the standard size for 1 1/8" headsets. The reason we don't list the size is because as far as I'm aware all 1 1/8" headsets use the same size crown race, they don't differ like the old 1" versions used to.
