They came with a bike second hand. I didn’t notice it till I took the bar tape off. I haven’t ridden them.
It looks as though the broken and cracked areas may just be fairings that wouldn’t affect structural strength but I don’t know for sure. I have seen carbon bars that don’t have this bit.
Can anyone shed any light on this? Can I do a strength test at home?

The first pictures wouldn’t worry me. The crack in the last few however would.

Call me a fuddy duddy (and I’m not an engineer who can offer any insight on the photos) but having had a bar break on me once, I’d change it if I have the slightest doubt.

I agree with you

broken and cracked areas may just be fairings that wouldn’t affect structural strength

Are the bars branded?

I’d assume looking at the pictures that the bars are made in one process and the fairings are added later- I’d be suprised if they added strength.

But if its on your mind…

yes they are New Ultimate handlebars.

thanks for the replies so far, I’m still in two minds.

I wouldn’t be putting that back on….!

I’m not sure it’s worth the risk. The extra bits do look none structural but i am not sure what the bit is in the last photo.

They are in a bit of a state and have either had a hard life or were not particularly well put together/thought out in the first place so I would say retire them and get some nice new ones.

It’s your teeth, but I wouldn’t be too worried about those bars. If you don’t want them my email is in my profile.

This is what a crack looks like 😉

Dead stop at 20 mph. Wrist snapped the bars (and wrist in three places).

As above replace them. You’ll never trust them anyway and always be riding with a nagging doubt that every ripple in the road could be your last.
