So I have a carbon fork that took a sliding spill. Maybe myself and the bike was dragged for 1 to 3 feet. Crash happened between 8mi/hr - 14mi/hr on an uphill.

Basically I landed on my left side. Some how didnt break my already once fractured clavicle; Yet my helmet this time fractured in two locations (both left side, along two different 'longitudinal spines' (if North and South correspond the the front and back ends of the helmet). The fork's paint is missing very specifically on the outer most edge (where it likely contacted terra). I dont see any other damages to the fork other than shallow scratch.

Is it worthy to have someone repair / relayer some new carbon over the outside; Or just replace the fork? We are talking about an entry level road bike, comes with a semi basic fork. At the end of the day I would like carbon in front.

How do we assign fatal accidents to carbon vs superficial scratches?

The fork blades, just some scrapes? Meh

The thing to think about is steering tube delamination if the bars hit hard enough (which seems like it would have to be a really hard hit). And if you have carbon bars, delamination at the edge of stem interface etc.

The important thing is, do you see any cracks? You may want to look with a magnifying glass as hairline cracks are difficult to see. You may want to take it to a reputable bike shop and have them look it over carefully.

If the verdict is anything unsafe, then replace the fork. If it's only superficial (as it looks in the pics), I would forget about it and just ride it as-is.

And REPLACE your helmet.

Low speed, laid on the side = low risk IMO and no worries. Higher speed front impact or side impact struck by another moving object means remove e fork and inspect steerer and crown.

Remove the fork completely from the bike and take off all the components (wheel, brake, and headset). Take a small cloth and use your hand to hold it the fork at the top of the steerer tube. Use a rubber mallet to tap on the fork legs. You should hear a resonating sound, if you hear a more muffled sound that means there is a crack.

I know every crash is different but carbon is stronger than most people think. I had a car pull out if front of me and I t-boned it at 25mph. I've ridden the bike as is a few thousand miles since.
