Carbon Fiber frame crack... Just one more ride..?(26 posts)

Carbon Fiber frame crack... Just one more ride..?-Dave-
Jul 26, 2002 6:57 AM
Hm... looks like that first attempt didn't post, Well I have this new carbon fiber bike, Got a crack between where on frame shifters would be. I have not dropped it done anything traumatic enough to crack it so I am going to send it in but i was invited on this ride tomarow... Is it safe to ride? It shouldn't be the most strenuous ride but I am just wondering if I ride it, will it break in half or something insane like that?

Don't ride, send it back. Go for a run or something. And call them ASAP to let them know.

How old is the bike? Call the place who made it and see what they say.
I have heard of spinergy carbon wheels failing and riders getting really hurt. Imagine the frame breaking and the twins get caught up on some carbon fibre uuuuughhhgh.
duct tape it back together?JackDanielsFSU

Duct Tape it together! Man that stuff is great!

Jk. I woudlnt ride it. Borrow a bike from someone else or rent one from your LBS. See if they will give u a loaner till you get your frame back.

Ah alright, Well the deal is, It is a new bike, only a month old. There are two bolts on the frame across from eachother and the crack runs between them, I am asuming someone didn't tourque them right at the factory, It just showed u p a couple days ago, I have been doing nothing but normal riding, no crashes, haven't dropped it or anything.

and what about your frame "expertise"?Jekyll

Unfortunately your thesis is a bit in error - the CT1 has a Ti main triangle and as the crack is apparently between the shifter bosses that would rule the CT1 out. Sorry.
Oh and to the original poster, don't ride the frame.
was just kidding around........nmafrican

Just kidding. Paul

OK, CF1 is full carbon fiber and could be a culprit here...
I miss read the post to read CT1 and not CF1. Apologies.
I kind of doubt it sucks either way.
At that price it better not fail!! nmafrican

What frame is it?

I responded on the racing board, but I'll repeat here -- don't ride it. Carbon fiber is very notch sensitive (probably why the crack appeared in the first place -- bad placement of bosses. Any way, the down tube takes a pretty big beating in torsion, even when you're not in an all-out sprint. Borrow another ride or skip it. My $.02
Do you feel lucky?grzy

Seriously - composites tend to fail suddenly and catastrauphicly. That you have any warning at all and that you happened to notice it is about as lucky as one should expect to get. The stress crack is there b/c of stress and the fact that it can't handle it. Who knows maybe it will be OK on your ride and maybe it won't. Question is do you want to find out since no one can tell you with any sort of confidence.

Dear Magnum, do you still want a CF frame?Lone Gunman

Bending a frame as opposed to this? Yes I know this is an extreme case, but it can/does happen.
