Cutting a carbon fiber steering tube(3 posts)

I've been riding my new bike for nearly a month now and I feel pretty comfortable about doing the final cut on the fork and taking out spacers for the steerer tube.

My question is this: Is there any reason to cut the steerer tube other than weight and cosmetics (i.e., losing the spacers on the top of the headset)? Is it more dangerous to ride with spacers?
I've heard that there is a reason to keep some space (I assumebill

you're talking about cutting the steerer to eliminate spacers on top of the stem, not the headset, correct?) above the stem. By clamping the stem onto the steerer a bit below the cut, you supposedly clamp where the steerer is a little stronger and less prone to failure. Some stems themselves seen seem to incorporate some space on top of the clamping point, leaving space without spacers.

Assuming your talking about the spacers above the stem, I don't think there's a real need to cut down unless there is alot of steerer tube/spacers exposed and you risk impailing yourself in a crash. If you have more than 3cm below the stem, you run the risk of steerer tube failure.
