Stem spacers spinning

Yes you need to say remove 5mm below and put 1cm above (except you might not like the look) so ideally remove say 5mm below, put in a 2mm and put the 5mm on top.

picture all spacers below stem atm reckon the gap at the top between stem and edge of steerer tube is between 1 and 2 mm
you just need a gap between the top of the steerer and the cap.
whether this is provided by the stem or the spacer is a moot point..The camera down the willy isn't anything like as bad as it sounds.

so long as both bolts are on the stem, all is cool..

This is just one of many articles and forums saying you shouldnhave a spacer above the stem https://www.velonews.com/gear/technical-faq-spacers-above-stems/

only because they're risk averse and want to be sure the stem is actually properly clamping on the tube and not crushing it by having a clamp above the top.elbowloh said:

SLAM IT. (just cut it properly too)
EDIT: having a 5mm spacer above is worth doing not least because it gives you more flexibility. which might be to change stems or to rise slightly.
Also this whole slam fetish thing is a bit daft really.1 -
That's not a description of being risk averse, that's a description of sound engineering and assembling as designed.david37 said:

well the whole system doesnt require a spacer above. it does require a sufficient gap between the cap and the steerer. Its easier to encourage the use of a spacer to achieve that since its more forgiving for home mechanics and more in line with most bike shop mechanics powers of thinking things through.elbowloh said:

The MFs are right. sort of

It's also to prevent crushing/fraying the carbon at the top of the steerer.0

Both ways are equally acceptable and have their advantages and disadvantages
Spacer above- less critical cutting of steerer, more flexible height setting, slightly stronger?
No spacer- neater, better if using a short bung/expander as the bottom of the stem is still supported internally.0 -
If the OP is still around,
When tightening the top-cap/preloading the bearings, don't overtighten the bolt. It can cause the bearings to bind and accelerate wear and pull up the bung. If using an allen key to tighten, just using the stubby side is enough0 -
Cutting a steerer to suit a slammed stem only requires a level of precision.*
Using spacers requires less precision. Other than that a properly assembled headset and clamped stem is clamped regardless of the number of spacers.
*It also requires never buying a higher profile stem.The above may be fact, or fiction, I may be serious, I may be jesting.

FFS How long is this going on for? Anyone with half a brain who has never seen a bike before could have sorted this basic bike problem in a few minuets. Anyone without half a brain could have found out what to do on you tube even quicker.
I just hope nobody with a rocket problem contacts this forum.0 -

FFS.
If everyone just listened to MF and slammed their stems and cut their steerers properly in the first place none of this would happen.
its not that difficult.

do you know how difficult it is to crush a carbon tube from any direction, let alone with a 5mm allen key?elbowloh said:It's also to prevent crushing/fraying the carbon at the top of the steerer.

You better tell Froome his stem is setup all wrong. The fool has a spacer under the stem. (refer back to your pic)0 -
no, they don't. they strip threads and phuck stuff.elbowloh said:

True. Mmm and his recent loss of form.......maybe stem related too.0

well, I'm not saying thete isn't smoke without fire but Boonen didn't have any of that rubbish under his stem and never fell off into pavements..

Geraint Thomas also has spacers under his stem and look at how he falls of basically every day........
