i.e without a spacer, I presume this is ok?

Yeah as long as your stem sits a bit higher than the steerer.

Edit; It's strictly not okay if it's just for looks.

If that where it's most comfy, then do it!

Just be aware that short steerer-ed forks can be hard to sell on...

On a road bike it's mandatory. No need to justify it, just follow the rules.

You need at least one spacer in there don't you? To avoid crushing/damaging the headset. Even if it's only 2mm. The base of your stem isn't necessarily the best thing to contact the top of the headset with.

Yeah, this is what I'm wondering and not sure about...

No you don't need any spacers at all, they have no functional purpose apart from lifting the bars. Bars lower is one of the top tips I got from a training day with shaums march a few years ago, ever since all my bars are as low as possible to move more weight forward.

I've run a stem straight onto the split collett (no top cap) to get the bars low enough.In addition to a 17 degree negative rise stem- Elite roady!! 😯

It makes absolutely no difference whether it's the stem or a spacer.

Why not? The force is identical.

If its a carbon steerered fork, I believe you can need at least 5mm of spacers between stem and headset and at least 5mm of spacers above the stem/below the top cap. I think I read that for rockshox carbon steerers at least?

No, there is no minimum (from RS manual)

[i]Carbon crown-steerer: remove any burrs
from the stem clamp edges then install your
stem according to the manufacturer's
instructions. Install a 2 mm spacer above the
stem to allow for proper headset adjustment.
Do not exceed 30 mm stack height when
installing spacers[/i]

"slam it". Most retarded sounding phrase of the decade. Must add that to the "phrases you hate" thread.

Remember you can bend your arms if you want to go lower.
Mine have been raised for a more sustainable aero position when in the bunch

Makes no difference at all if its a spacer or a stem. Its still a cylindrical bit of metal in compression, aslong as the stem cap bolt is done up tight enough. i suppose you could cause some slight cosmetic damage to the top surface of the headset top insert if its the stem clamp in contact with it, but no more than you'd do to a spacer.

Both of my mountain bikes have their stems, ahem, slammed, due to length of head-tubes and length of steerers.
