    You can only do that if there are currently spacers above the stem. In which case you just move the ones that are above to below the stem.

    If there are no spacers above the stem then you'd have to either get a new stem with more rise or new forks with a longer steerer.

    You can do this if there are already spacers above the stem, you just place them beneath the stem instead. If you don't have any above the stem you can't just add spacers, you can only have the stem as high as the fork steerer tube (to which it clamps) allows.

    The other options are to buy a stem with a greater angle of rise (or and adjustable one); buy a steerer extender, or buy a new fork and don't cut the steerer tube down so far.

    damn, beat me! :evil: :wink:
  • Can you spin the stem around? would that increase the angle?

    Flip the stem. If it has a drop/rise on it and is currently in the drop orientation then flipping it will indeed raise the handlebars slightly.

  • WHS ^^^ the original stem is + / - 6 degrees (looks level when viewed from the side due to the rearward angle of the frame steerer tube), so turning it over will give you a useful rise in the `bars.

  • I have flipped it it looked fine then a noticed the rattle. It does not seem to fit on the spacers as well its a couple of mm gap.

    Strange, it should fit exactly the same. Have you got a photo to show us the mm gap?

  • Sure you didn`t drop a spacer? If not, are you sure you`ve tightened down the top cap properly BEFORE tightening the stem bolts? Top cap bolt just need nipping down to take the free-play out of the bearings before the stem bolts are tightened.

  • I have cracked it now. It spoils the look of the front end but it feels nicer. I think i must have short arms.

  • i don't mean i cracked it as in broke it. cracked it as i solved the problem. The sleave that fits into the stem was nor in the correct position.

    Short arms would mean a shorter stem is required. If it's uncomfortable as it was then that more likely suggests your back isn't flexible enough. Not a problem but you'll be more comfortable if both length and height are correct.

    If you have a sleeve in the stem, is it an adjustable stem like this? If so, rotating or swapping the shim allows for stem angle adjustment.

  • I'm not getting any pain in my back. It feels like i'm straining my neck looking up from the riding position. I thought getting my head further upright might make things better.
  • You`ll get used to it, your neck muscles will adapt to letting you look ahead better. I was like this at first when I got a road bike, after mor eupright MTB position.

  • Just got back from a ride after changing the stem. It feels a lot better. However i got my first puncture when looking at it i was moving the handlebars back and forth it didn't feel as smooth as i'm guessing it should. It has a bit of resistance. I thought maybe i over tightened the headset when adjusting. Just loosened it, it not that. Could i have done something wrong putting it back together? Do you reckon it was always like that and just noticing now? Could riding it with the puncture done something? its not totally flat it just lost some pressure.

    Sorry if it is stating the obvious, but if you loosen the top cap whilst the stem bolts are tight, nothing will change (you could even run the bike without the top cap once the stem bolts are tight). Loosen stem bolts then adjust top cap, retighten stem bolts when smooth but no play (grasp the bottom of the head tube around the headset, put front brake on, rock back and forth, you will feel any play).

    But I guess you knew that :wink:
