I'm a muppet...let carbon forks drop from frame!

I was dismantling the headset on my Scott Foil which was in the workstand, and for some reason I didn't think I had released the front brake cable yet but I obviously had because the forks dropped to the concrete floor in a massive clatter before I could stop them!
I've built so many bikes over the years I feel like such an idiot for being so stupid!
The paint has chipped on the bottom of both dropouts, and on one dropout there is a crack in the edge which is a sliver of carbon (see pic).
I'm probably going to have to replace the forks aren't I? A costly mistake this!

Still ridable I think, but keep an eye on it (take the wheel out after ride and check if parts come loose)0

I wouldn't risk it0

300g from a few feet, nothing compared to 90kg at 50mph through a pot hole.0

They're made from carbon fibre, not glass - if you want to satisfy yourself youtube "Cannondale Taurine vs Hammer".Make mine an Italian, with Campagnolo on the side..0

I'd waggle the dropout a bit to see if it's cracked, but I reckon that's OK.- - - - - - - - - -

Having looked again, it looks like it's mostly part of the raised safety tab that's tried to peel off and hopefully not the dropout itself. I see Westbrook sell Foil forks, well they have 2013 ones on their website anyway, for £1800

the lawyer tab is part of the carbon drop out isn't ?
i d pay the £180 or whatever, as just knowing that it was damaged would take the edge of riding the bike but thats me, you may take a different view to risk.0 -

Not the same thing at all.0 -

True; when you hit a pothole the force is transmitted to the forks via the interface between the dropouts and the axle / clamp, so a larger area takes the stress compared with the very tip of the dropout bouncing onto the garage floor scenario.
But looking at the photos I still think they'll be safe to ride..0 -
If this were a pair of lightweight aluminium forks it had happened to then I don't think I would be worrying. But the fact they're carbon makes me nervous, not sure if I should be or not!
Someone on Singletrack has said the dropout is actually alloy, but I don't know if that's right?0 -
That looks like a paint crack. I'd be tempted to flake it off and see what it's like underneath?0

The dropouts on my CR1 are carbon. I believe it says so on the rear stays somewhere. Still pretty much pristine after 2 years of clamping / unclamping wheels and riding through potholes. Can't say the same for the wheel rims.0 -

Off you go and do a full finite element analysis then! :P0 -

Why bother? It doesn't take that to understand that your simile was poor.0 -

You might want to go and look up the definition of simile instead...0 -

What it really comes down to is do you trust them. If the answer is no, then bin them and buy a new pair.0 -
Me too. It's quick and easy to whip the front wheel out occasionally to check.
To me the meaty bits of the dropout that take all the force from the axle / QR clamp look fine0 -
I went out on the bike last night and felt confident enough for some steep descents and country lanes. I really can't afford £180 right now0

I'd have to agree with that, I'd just ride them.To me the meaty bits of the dropout that take all the force from the axle / QR clamp look fine0 -
I`d ride on them. A short drop like that should not cause any fatal damage.Trek,,,, too cool for school ,, apparently0
