Carbon Fork - Aluminum Crown(3 posts)

I'm riding a Time Stilleto fork that has a white painted finish. I noticed a small horizontal crack about 3/4 of an inch from the top of the fork on 1 blade. Contacted Time and they said that the aluminum and carbon flex at different rates resulting in the paint cracking -isn't supposed to structural - and that this shows up on some painted forks. Apparently the clear coated forks don't have a problem as the clear coat is a little more flexible.

Anyone else seen this??
Thanks.

Yes, it's fairly common. It really shouldn't happen, but it does. Just keep and eye on it an see if it gets larger which would indicate a bond failure. You don't even want to contemplate what happens next....

trek even named their frames after this, one crack 'long void, to indicate that at all of their lugs, this will occur. ;)
