You't think, right? I can imagine seeing socks over shoes from this person.

It's great that you spotted this, and you even investigated it further. You know you are going to replace it. If nothing else because you put the MoJo on looking into and posting this thread. So now comes another decision and that is...

Do I replace it with another one just like it?
Replace it with Steel or Aluminum?

Either way its replacement is going to bring ya much relief...

Note: I don't have a Carbon bike, but its not because I don't want one... Ha

Not even because there's been structural damage to the carbon fiber tubing... there probably hasn't been. (Although I have no confidence in my ability to sand carbon fiber without damaging it.)

I'd replace it because, while I often have conversations with the voices in my head while riding, I wouldn't enjoy it if one of them occasionally whispered, "Hey... what about that fork? You know, if it broke right now, you'd totally die..." just as I'm braking into a hard downhill right-hander. (Yeah, yeah, I know. Sometimes they lie, and they're often wrong. But they don't always lie, and sometimes they're right.)

Yeah, but not everybody rides bikes like a Fittipaldi. I'd say, if you are not tempting the devil on your bike rides, I'd say it is OK. But if you test how fast you can go downhill and brake later and later into that familiar corner to test your limits, maybe it it not a good idea to ride it. Riding in a city in a heavy traffic also can be just as dangerous even at low speeds.

But if not taken to the limit, chances are very good that you will spot something is developing before it actually fails totally. I mean, we all need our lucky star, guardian angels, else nobody would survive to old age.
