Sirrus Stem Problem

I'm using a Specialised Sirrus Stem on my bike because it just so happened to have the right angle and length on it, but I've found a problem.

The two 'flats' where the spacers come into contact with the stem don't seem to be parallel, the one that would normally be on top but is now on bottom because I've flipped the stem is making the bearing cap sit at an angle.

Here's a picture of one of them online, they don't even look parallel on this, why on earth have they done it? Mine has that spacer looking thing on it too, but is doesn't look like it's removable considering it's part of the inside of the clamp area, so taking it out would make it larger than 1 1/8.

That sounds pretty sirrus. Not sure I can help you.

Ah, this is more evidence of Specialized brilliance- there is a wedge spacer between the stem and steerer, so the axes of the stem hole and the steerer are non-parallel. Loosening the stem and moving the spacer around so that it is 180 degrees around will change the angle of the stem- if you look closely in the hole between the two clamp bolts, you will probably see the angle shown- probably +8 / -8 / +16 or -16 usually- once you pull it apart all will be clear. Don't worry too much about how the cap pulls down, it's not critical and as long as the headset bearing preload is OK, you are fine. The special spec cap is assymetrical but any top cap will work well enough I think.
Good luck.

Thinking about it you may have to keep the spacer with the flange down (if you are intending to FLIP the stem), but inspection will tell you soon enough.

Top banana, you are an utter scholar. Sorted it all out, no longer have any buggeration going on, had to chop the steerer down to lose the spacers above but using the specialised top cap seems to have sorted everything out.
