After a thin washer that sits above the upper headset crown

primalcarl

Where can I find one of those super-thin washers that sits on top of the split crown on the upper part of the headset? Have tried the usual places like CRC/Wiggle etc!

it will depend on the headset, there're umpteen different types

there're headset shims, for instance...

...but not much use if it doesn't match your headset

Thanks for that, looks spot on. When you say different types, different how? It's gotta be 1 1/8th, thin and wide enough to cover the top contact area of the tapered ring
