Carbon steerer tube scratches
Hi , when i was changing my stem today i found a few scratches on my steerer tube. There is a particularly long one which is deeper than the others. The scratches are very shallow but deep enough so that i can feel them when i rub the tube with my finger. Since this is a carbon steerer tube i am worried about cracks developing and eventual failure. I read somewhere that carbon products may fail if the scratch is beyond a certain length in deepness. Please advise.

What direction do the scratches run? If they are lengthwise along the steerer tube they probably aren't a hazard since, at worst, they will cause the steerer to split lengthwise. Not good but it won't cause a catastrophic accident. If thete is a deep crosswise scrarch, I'd be concerned since a fracture across the steerer tube will be very serious.
You might want to contact the fork's manufacturer for a better judgment call.
