Are carbon bars dangerous?
#27
I wonder if there is any objective statistical evidence based on a large enough sample to be meaningful that carbon bars are any more prone to JRA failure than are alloy bars. If someone could point me to such a study, I'd really appreciate it.
In the meantime, every time this topic comes up it seems we get a lot of personal anecdotes one way or another but no real data. I've used both, taken the same care with both (yes, I own a torque wrench), and had zero issues with both. But that doesn't prove anything.

If both side break off, you have to grab the stem. This takes practice. A good training aid is to make up some wooden drop bars. Most carve them out of old hickory. Mount them up and then ride the bike and then break them off with your hands. As your face falls toward the head tube, learn to grab the stem. If you miss, all that should happen is you get a ding in your forehead. Shouldn't be a big deal.

I'm pretty sure the torque wrench is required to ensure you don't OVER torque, thus cracking the carbon.

With all due respect, check the statistics. Somewhere between 44,000 and 98,000 deaths were due to preventable medical errors according to the report published by the Institute of Medicine in November 1999

The health care system, including doctors, is far more likely to kill you than carbon handlebars. Be very afraid indeed.

Based on a single experience, second hand, with many unknown factors, aluminum bars are the ones that will kill you.

I have had carbon bars on my bike for six years without any problem. Unless you are in a nasty crash or you over tighten them, you will be fine.
By the way, I picked carbon because I could get the bar shape I wanted. However, aluminum is now available in ergo shapes.

As to bars, I have them on the tandem. No problems in two years. I have them on my go-fastie CF bike, and no problem.
I have aluminium on my old touring bike. In 2003, it fell over in a campsite, and bent the right drop in 10mm or so. I've been meaning to replace the bars since, but because they haven't broken, and I haven't tried to pull them back into shape, I figure I don't need to fix something that is not broken.

This is NOT meant to be in bad taste, but who knows... but Carbon Unit, maybe you should talk to your surgeon about inserting carbon fibre mesh in your hernia. A bit of good quality weave, and it should last forever.

Hey, I like the idea if it worked. The carbon bars on my bike may never break because it may only see trainer duty if the doc won't let me ride on the road again.

Sorry if you took it personally. Definitely not my intent. Maybe it's the irony that escaped you. I mean, here we are once again wringing our hands over a perceived hazard for which there's not a wit of empirical or statistical evidence when there are other well documented dangers out there that few pay much attention to at all. Just sayin'...

Oh, I understand the nature sarcasm quite well. You just got a sample of my particular brand of it

No. He's probably right. I think we should all just quit so that we stop killing people. I'll just become a waiter or a lifeguard or something. I'd hate to cause more harm.

Like I said, it's all about the warped perception people have of risk. Besides, waiters and lifeguards can do some pretty serious damage too

Crap. Now I have to move to that deserted island. Wait. Look at all the damage Gilligan did! Oh, I give up

dont forget the carbon paste,works great ,you dont have to tighten the bolts as much and no slipping. That said i ride carbon bars,love em,but i'll tell you they suck after hitting my face on the stem after they blow up so whatever.

Can you be a bit more specific about this hitting your face on the stem? It seems that if we are to inject at least one real incident into this "reality" we might as well have the details. When, how, what side, where, result, and any previous incident that might have led to the failure.
