Help slam the stem of my bike - Giant

[mustafah009]

Does anyone know where to get a shallow conical spacer to slam the stem of a Giant Advanced Tcr 2?
Picture attached.

Thanks!

Have you looked under the conical spacer?

Possibly you have a setup like this? In which case just remove it.

Yes I've checked under the spacer, there's nothing there.
Thanks for your comment.

I would get a -17 or -12 stem before trying to reduce the conical spacer size. Or do both while you're at it

Thanks. I've just bought a -17 stem, will give that a try.

Conical spacers are amongst the hardest part to buy in isolation in my experience. It must be made to fit the top race bearing. Your Giant, being 1 1/2" steerer, would pose an even harder challenge. I suggest getting a new headset might be easier. Take the conical spacer and the rest can serve as your spare parts. GL

It's a standard 1 1/8'' at the top on this model (hence the deda stem)

This is correct

Recently slammed the stem on my defy advanced (guessing it's the same headset). Used a Ritchey comp dust cover with a 5mm (or 3mm, can't remember exactly..) spacer underneath. The Ritchey cover centres perfectly on top of a standard headset spacer, and the spacer aligns with the wedge to load the bearings. The setup leaves <1mm gap to the top of the head tube, resulting in a super low stack hight (around 4mm).
