I have recently bought a Felt Z35 which has a sloping spacer beneath the stem, which sticks out a bit in front of the other spacers.
There is a close up of this stem on this website -

In the picture they have the sloping spacer above the headset which isnt how mine came and it wont sit flush when I try it that way round.
Does anyone have one of these and how do you have it set up?
