I'm glad you weren't hurt, but honestly, I don't believe we're getting the whole story. This just doesn't add up. You don't just ride around at a reasonable speed and have both sides of your fork fail simultaneously in the same spot.

I'm really not trying to be a jerk, but I don't believe what you're telling us is the whole story.

i just crashed my caad9 6 this very morning... 24mph. just coming down from a slight overpass and nothing happened to my frame or fork and i weigh 212 lbs as of last saturday. i had to go to the doctors to deal with the neck soreness and road rash.. along with the pride of ruining my best morning commute gear... i smell foul play, but if im wrong i apologize.

vibrational fractures in carbon dont tear in unison because when it fractures it does not pull other strands with it such as this example of extention stress.... all im saying

Did you crash the bike at all prior to this accident? Micro-cracks in carbon fiber are usually not visible to the naked eye; this might be a case where previous damage resulted in catastrophic failure.

Glad you are doing OK all things considered.

The people in cars behind us that saw it happen said the forks hit the ground, me, being clipped in caused the bike and everything else to go over the handle bars. landed on my left shoulder blade and left hip. sliding for a few feet and finally stopping.

I would guess that this is not a spontaneous fork failure. The forks failing at the same height on both sides seems pretty random. Possible something from a passing car got thrown at us or kicked out at us and caught in the wheel. We searched for anything that could have caused this and found nothing. Assuming that in order to sheer forks like this it had to be fairly substantial. Nothing was found.

I am guessig that the frame bent as the stubs of the left over fork slammed into the ground with my weight and momentum on it.
That kinda sounds like your front skewer was loose and some road vibes caused the wheel to come out of the dropout.

Please don't show me this! I just got a call that my new CAAD9-4 would be here on thursday. Now I'll have to keep him from going on the internet and being traumatized by the carnage.

That's exactly what it sounds like, but the pictures show the remains of the fork tusks clamped in the skewer. I have to assume the OP didn't pick the pieces up and put them back in. Anyway, the ends would be seriously messed up if that happened and it'd be obvious.

Solved! Good detective work.

But wouldn't the same thing apply to the ends of the sheared section? If the place where the forks sheared hit the ground with enough force to BEND A STIFF ALUMINUM RACING FRAME don't you think the carbon would at least be severely chipped and more likely destroyed.

Plus he says he basically injured nothing, no statement of road rash (except on the bike, which cannot really be seen it the pictures), broken collar bone, dislocated shoulder, etc. seems strange, not impossible but strange.

OP, I am not saying it didn't happen and am glad that you aren't hurt but from our point of view you have to admit it seems very fishy.

I never said that I was unhurt. I have a huge case of road rash all the way down my left side. From left shoulder to left hip. Bibs were completely torn and ripped. helmet was dented in the back even. The buckle on my left shoe was even blown apart from impact with the road.

the ends of the forks that are still attached to the wheel are the same as they were when I picked the wheel up after it happened. the skewer was still in place and holding tightly to the sheered ends. The fork ends on the bike were/ are chipped and splintered and otherwise destroyed.


The front wheel did not come off due to vibration. Something had to of gottne in the wheel and hit the forks hard enpugh to break them. that is the only explanation that I can think of that fits.

DScott 10-26-09 06:35 PM
I see no reason why you wouldn't be telling it like it is.

Do the broken ends of the fork tips match up with the stubs still attached? I'm wondering if the impact ground down the stubs at all, or if the pieces still fit together...

Why are you all out to get the OP? Really, I mean, what's the deal? Fork snapped for whatever reason, bike turns and hits a different part into the ground (headtube or handlebars?).. and there you go. The remains of the fork on the frame don't have to be smashed, chances are the bike did not continue to go perfectly straight after it lost the wheel. Think people, come on.

I'm not out to get the OP,but I just think there are parts of the puzzle that are missing.

To OP:

Did you buy this bike new or was it used?

Has there been anything that could damage the fork?

The old 'frame pump in the spokes' trick takes out almost all the spokes and then kills the fork, there are still a good portion of the spokes left in that wheel.

What are we missing here?

Relax, cubbie. You have no idea what happened, and neither do we. That's why we're asking questions. I for one, would like to know how and why this happened so I might not suffer the same fate.

I'm just sayin it seems like everybody wants him to not receive help from cannondale. They all want to be able to laugh since he's out a nice bike.

CyciumX 10-26-09 07:56 PM
the frame damage is the oddity. even if the forks snapped and they hit the road the angle of impact would have the frame flying the backend over.. channelling a lot of energy into other forces not related to a bone in impact. the headset would need to have hit dead center to allow the bike to bend and come to a dead stop.

my crash accrued zero damage to my caad9 frame and fork....of course i had to buy new bartape and reset my brakes and its all scratched to hell....

I think its Victor plum with the candlestick in the library?

mmmdonuts 10-26-09 09:00 PM
Whatever got into your wheel was at least as tough as a squirrel.

Cannondale frames are not that tough either. Just because they are stiff doesn't mean the tubes won't dent and bend when hit. It doesn't take all that much of an impact against an immovable object, such as the ground, to mess one up.

Squirrels take out wheels, they don't take out carbon forks.

I learned from watching 'House' that all patients lie. One way or another, this is the case here.

Squirrel + Carbon Fork = :eek:

I stand corrected. What was the chain of events?

Was it: squirrel in the wheel, takes out the spokes, fork hits the ground, fork breaks and catapults rider.

or

Was it: squirrel in the wheel, fork breaks and catapults rider.

Either way it looked ugly, but I'm surprised that a small animal can take out a fork all by itself.

You walked away, good for you

I won't add to the speculation.

The story is: Squirrel went into wheel, snapped fork, rider went down and sustained serious injuries, squirrel didn't make it.

Wheel/spokes were not destroyed and fork legs were still attached to the axle. Much like the OP's.

I was riding to work. Going 25 (according to Garmin). A gust lifted up my front end. Seriously, I got lift, and turned my front wheel a little. When my wheel touched the ground the fork snapped in half, broke. I tore up my arms something fierce. My heart rate monitor chest band is scraped out of commission (thank god I was wearing it and my chest is ok.) My fork snapped in half. My front wheel had a few spokes pull out of the hub. So I need a new wheel and fork. I've got some road rash and maybe micro tears in the muscles in my shoulders. All things considered, I'm alright.
It was an unpleasant experience, accentuated by the fact I've been waiting for a month to get my steer tube cut, which I finally got this morning. My poor, poor bike. She's only got some 500 miles. RIP(es) fork.

Well, there's your problem. They used packing tape on the fork instead of duct tape.
