Damaged Carbon Steerer Tube, repair/replacement? I cracked the top of my 2007 Schwinn 1 1/8 fork black label steerer tube.
What kinds of repair are available? Should I just buy a new name-brand carbon fork, e.g., Canondale, GT, Trek on ebay?
The standard line from the carbon repair shops is they don't do forks because new ones are a lot cheaper. My understanding is that safe steerer repairs are technically possible in a lot of cases, so if you want to go nuts or if the original is unique in some way you might be able to find someone to do it, but it's probably not worth it. I think in practical terms, the real problem is that a lot of the time if one part of a carbon fork is destroyed, the rest might be pretty well-loved also.
The usual approach is to measure the axle-to-crown and offset dimensions of the original and go shopping for something close. Among carbon rim brake road forks, there's not a lot of variance. A number of companies make what are essentially repair forks for this kind of situation.
