    Carbon crown race area looks chipped

    I've attached a picture of my full carbon fork's crown race area. If you look at the base of the steerer, it looks like there's a bunch of chipped/broken carbon inside the fork crown race. This is the first full-carbon fork I've had and it's only a few months old. I installed it myself and can't tell if it's supposed to be like that or if I did something wrong. Is this something I should be worried about? Thanks in advance!

    I wouldn't be too concerned about what I'm seeing in the photo. The steerer, being the smallest crossection, is usually the greater issue, and it looks to be fine by my eyes.

    But you do raise a point in that when a carbon crown race is somehow damaged or not right what is the recourse. With metal crown seats one can remachine them (to a degree). If a carbon one is so bad as to not allow the race/bearing to sit properly what's to be done? Maybe adding material as in JB Weld? I am pretty sure the manufacturer would say to replace the fork.

    How old is the fork? Any chance of a warranty inspection? Andy.

    If a major brand, the warranty may have been voided by self-installation as opposed to an authorized shop mechanic doing it. Dunno. Just sayin.

    If it's only plastic you need to replace and none of the string's broken, well hey - why not?
