Cracked carbon forks? Opinions needed!

So I think I cracked my Alpina carbon forks, heard quite a significant sound like someone snapping a piece of plastic and pulled over and under the dim light of an ATM saw what seemed to be a crack. Not sure if it's in the carbon or just the paint, feels like a crack after running my fingernail over it but have put roughly 50km on it since and it's fine, accidently twatted a pothole today as well, Opinions? Greatly appreciated etc. yadda yadda

1 - take the wheel out, and grasping the fork blades, try to spread them with all your might.
2 - remove the stem and place forks in the bin.

You'd need to X-ray them to find out for sure I think, I would recommend following Prav's procedure.

As a point of interest, I now have two replacement teeth after hitting the deck with my face- they cost ~£2,600 each.

How much are a new pair of forks?

Holy Balls. What broke?

Just buy a new fork

• you could sell the cracked ones to somebody who a) can mend them, b) will just use them on a turbo, c) has big balls
  
  

Could put £20 back in your pocket, my mate sells all his knackered old gear, cracked frames, bent bars etc :)

^ i had a big crash, wrote off my frame but my forks look fine. I'm still too paranoid to ride them though.

don't bother, £100 or your face?

this is why cheap carbon is the best carbon. Had a crash and got some doubts about it? It's cheap enough to replace so no worries.

get a ct scanner http://road.cc/content/news/52205-canyon-proud-their-new-ct-scanner-their-what

it would be actually nice to have a place where you could send your frame/forks to be checked like that after a crash....

it's what insurance is for.

and then put something in your headtube that isn't made of plastic.

Mrs Bobbo runs the imaging department in a well respected hospital in London's famous London, hold on I'll give her a call and explain the situation just to see what she can do.

Mrs Bobbo laughed so hard it is highly probable that she has just wet herself.

She also says that it is a "silly idea"* to ride those given the potential consequences.

*not her actual words I have interpreted as her language made me blush.

How did you crack them out of interest?

^ the frame in an MRI and see what happens...

Worst case scenario, you would need to quench the magnet. VV expensive.

Only if someone is stood above the boil off outlet, which has happened before. Generally speaking if you have to manually quench a magnet it is because someone has become trapped between a ferrous object and the bore so you will not be able to remove them from the couch until the magnet is quenched.

could actually be an idea someone sets up shop scanning carbon frames, just think of spesh, in the uk ONLY for example, how many returns on potentially dodgy carbon do they have?
BrickMan Industries Crabone Fib'rey Scanning Division is now recruiting...

Holy Balls. What broke?

Cycling back from the forums second birthday, I was pissed and was involved in a collision, initially with a car, then ultimately with the road.

Broke my jaw on both sides, smashed two teeth off at the gum line, and sheared ~40% of the others diagonally resulting in a bit of a mess.

Which is a bit misleading- the reason I mention it is that the injuries I sustained are consistent with a fork failure, which, rather cheerfully, tends to be rather sudden for carbon fibre.

Reading this makes my mouth feel funny. And not in a happy joy joy way. I need to go to my safe place now, goodbye.

leaves forum and burns cycling equipment

Shitting hell. And here's me trying to get over my broken wrist. Hope you're doing ok now. That sounded (nearly) lethal.

Might not be your forks, could just be your bars. If your bars are not tightly secured they move slightly when significant sharp force is put on them. This noise is incredible and sounds exactly like plastic/carbon cracking. It happened to me when I rebuilt a bike and it shit me right up. I took out the forks repeatedly but could not find an issue,but the noise still occured each time I hit a bump. I found I could make it happen at will by standing over the bike, raising the front and forcibly bringing it down (at a non-fork breaking magnitude).

Took my whip to Bike Magic who were amazed. They found no fault and decided just to tighten everything. Issue solved. They said Charge Plugs or summin had a similar issue which causes concern to new owners, can't remember the full details.

Balmain on a TNRC had the same issue last year. I heard the noise, we tightened his bars and it was sorted.

^Yeah, but his fork looks like it has a massive crack in it.

Cracking noise + Appearance of crack in fork = cracked fork.

I wouldn't risk spinning around with that timebomb ticking over my front wheel. You'd be buzzing along, full of the joys of spring, then suddenly you find you've given yourself a 'Kerby' and a Toyota Yaris is trying to get a piggy back.

New fork, every time.
