Hello Jordan, would it not be logical to get an aero carbon bars with no holes ... It seems to me that the 2 or 4 or 6 holes on some bars weakens the structure.... The more cable holes the greater the chance of breakage? Do no cable hole aero bars exist ? What brand? I spent 8 hours on the net and the products rarely indicates how many holes or where ....

I have broken 2 race face next carbon handlebars in my first years of riding and my last nukeproof horizon carbon bar is like new after 5 years of heavy riding.

After watching this I'm even more happy I ditched the $300+ plastic, wing-shaped, flared, skewed, swept, etc. thing that came on my new gravel bike for a $30 aluminum drop bar in a totally normal shape. Couldn't be happier!

Thank you for sharing J. Great video as always.

Awhile back, I over torqued a stem bolt and cracked some carbon handlebars in the center. Before I tossed them, I tried to see how hard it would be to break them along the drops and it was near impossible.

A bit unnerving seeing s few pro riders losing their bars. I've had round conventional carbon bars and semi aero baro by 3T on bike for some time and no issues. I think tbh the main concern is if you drop the bike you really don't know how damaged the bars might be.

One word: Titanium. More words: I chose titainium for that exact reason. I never trusted alu, as I did bike trials (as in jumping around) and had one crack (not break entirely). Since then I purchased steel, and now with my latest bike, I decided to go all in and buy a custom titanium version of my preferred geometry. Titanium, unlike alu, doesn't mind flexing. Alu, if flexing will be fatigued instantly. Alu corrodes when robbed of air. Carbon: Hidden cracks and delamination. Neither a problem with my titanium version. That said, the holster and the foot itself on my prosthetic leg is carbon fiber, and the hardware and tubing on it is Ti.

But carbon splinters when it breaks. You may get a cut from aluminium sharp edges but splinters from carbon no thanks! Alloy can also Corrode over time and fail.

Nice one - the stress risers on those Specialized aero drop bars were insane: the cable hole and the aero/drop transition are unforgivable. No wonder they broke there. Unless you're at the sharp end of racing and need the aero or hill climb ultra-light, there's just no need. They save no significant weight, they're silly expensive and they fail suddenly. Straight mountain bars aren't too bad because they can be made in one, but they're still vulnerable at clamp areas and from crashing.

I had a carbon stem on my last gravel bike. I took it off to set it up to sell it. I spoted a crack in a top layer of carbon. It looked like it was possibly more cosmetic than structural as it seemed to be an additional layer added to the stem. Or, maybe it never bonded properly?

Carbon forks with aluminium steerers are more likely to break than all-carbon forks. The weak spot is where the cabon meets the metal because they have to be glued together. A quality carbon fork is made from fibers running in one piece from the dopout to the end of the fork shaft. What you still have to do is to clamp your stem with proper torque.

I’ve had my Easton EC90 since 2006 on my cyfac and they are tough.

But what I wanna know and what I have never really gotten a really good answer for is why is it that you can’t repair carbon handlebars but you can repair a frame. If it’s purely from a liability standpoint, then to me, it would negate the reliability any carbon repair. There are chaijstays that are pencil thin. I suspect is much more likely that the carbon frame having more mass in the area has a much less likely chance of catastrophic failure, and hence why people are so unwilling to work on handlebars where if they snap you lose control. but again for me if I am to trust a carpet frame repair, I should be able to trust handleable repair just as well.

There is a reason you can buy cheap Chinese 70 pound bars made of t700 carbon.
