Yes. you'd want your shim to be flush with the top of the steerer tubeDaveM said:Ok thanks for the reply andy, I cut the steer shorter than the stem but do I have to cut the stem shim (1 inch steer) so that the shim is 4mm shorter than the stem?

A 1" steerer inside a 1 1/8" headset ?
And you're asking if the shim needs to be exactly the same height as the steerer itself ?
Wouldn't have thought so, providing both steerer and shim are just a few mm shorter than the stem enabling you to be able to tighten-up the top cap to load-up the bearings, and neither far too short so that the stem isn't solidly gripping the steerer, I'd think it's fine.
