Carbon steerer problems... eek do I need a new fork?

So, now, when I take the stem off and look at the top of the steerer,
I can see that I've sort of dented and slightly squashed the top of
the steerer.

See if you can sell the fork s/h to someone who will be able to
cut it down to below the damage (which will be safe to use),
then buy a new fork and chalk it up to experience.

If you've squashed the steerer then the stem isn't going to
grip like it's designed to. This will a) make for a weaker
coupling and b) make the stress uneven. Both of these are
bad things.

Of course, it's you that has to ride the bike, but please
don't crash in front of me!

i don't think that carbon gets fractued like alu does so it shouldn't
degrade in that way though it doesn't like impacts nor sun i'd guess.

I forgot to mention the crash damage...

mind you any frame if you'd attaully damadged it then it's probably
worth bining the frame.

I don't see why it would cause a problem as long as the bung is in the
right place - the steerer should squash back into the right shape when
tightened, and I imagine the critical part is just below the stem rather
than inside it (the bit just above the crown is probably the most
stressed area, but I imagine that will have extra layers of carbon - if
it doesn't then the top end is probably well over-specced anyway).
