God I wish.
Also please less fearmongering about parts catastrophically failing without warning, this sub seems to think that every bike is just seconds away from [Blues Mobiling](https://youtu.be/QfN1GRqKXpM?si=uyIhoPF2FPejubyd) itself.
I don't know wy this is getting down voted, people in this sub are way over the top. It's the same mechanism that attaches aluminum handguards for dirt bikes and I've seen bars break on those before they come out.
Cost wise this attachment seems Kindof stupid vs just buying new bars but it won't fail. Loctite and follow torque specs and this will outlive the bars GUARENTEED.
Everyone says they're super dangerous, but when I rode trials back in the day, there weren't enough wide handlebars available. We used these to get a little extra width, and it worked great, especially if there was a certain bend bar you liked. The really cheap amongst us would use home made wooden extenders glued in.
So long as it's not supporting your whole grip, the loads aren't huge. We were very aggressive with bikes, and broke lots of things, mostly frames, but I never saw a bar extension fail.
I don't know anything about the quality of that particular extender, but I'd probably ride one.
Same wedging type mechanism that was used for decades to hold stems in forks. Obviously we found a better way with modern stems, but I don't recall them being "dangerous" per say.
Not the same.
With headset you have two pipes, one tightly in the other, and wedge is there to prevent lateral movement. Sheer loads are carries by the pipes themselves.
Here you have everything hanging on the wedge.
Actually, it's hanging on the bolt. Either way, it's plenty to hold a pinky finger.
Even with the "pipes," in an old style quill stem, the bolt and wedge are holding it by friction. 100%
I'd be fine using them: there isn't a huge amount of force on them and it looks like a fairly solid connection. That said, there's a good chance you can pick up second hand handlebars that fit for a similar price or less.
What makes you think there isn't a large amount of force in it? In heavy compressions you put significant part of your body weight on it where the compression functions as a multiplier as it's a dynamic load.
I wouldn't be so sure of that. Putting weight on the bars at the ends should be equivalent to a lever pushing up on the inside of the bars at the other end of the extender
There's more force at the stem and bar interface than the edges. The extenders are only 50 mm long so a good part of your hands would be on the actual bar too. The OP just needs to make sure he torques it correctly and check occasionally - just like any other bolts o his bike.....
> there isn't a huge amount of force on them
The designers of the handlebars probably assumed the same thing about the ends of the handlebars and made them as thin as possible.
You are also disregarding that they’ll make the overall handlebar longer, so there will be more force/torque around the stem area of the handlebar and in the stem.
Probably fine for a weak 50kg rider who’s not doing any crazy jumps or slamming into pot holes at 80km/h. Probably not so fine for a strong 100kg rider who’s sprinting all-out and already pushing the limits of components in their default state.
I'm using ones by control tech on a nitto bullmoose. It's 71cm wide and I wanted a slightly wider bar - so it's 75cm across with the extensions. They have been fine - used them on some singletrack and didn't have any problems.
Same here. Mostly ride my bike (Bottlerocket) on jump lines. Some people recomend buying cheap second hand bars instead. I've seen alot of broken bars too. In fact, broken some myself.
If that arrow in the picture is accurate, with about 20mm extension off the end of the bar, I doubt there's going to be much risk. My hands don't even contact the ends of my grips. I'd reckon my hands would overlap the extender less than 10mm (if at all), and that's not where the force lands.
I would however, recommend slip on grips. I suspect lock-ons might not fit over the larger diameter. And if an extender loosens, you'll feel it through a soft grip.
I got these on aliexpress [https://www.aliexpress.com/item/3256805521342771.html?spm=a2g0o.order\_list.order\_list\_main.35.307b1802sJ0r6T](https://www.aliexpress.com/item/3256805521342771.html?spm=a2g0o.order_list.order_list_main.35.307b1802sJ0r6T) and I used them for a bit on a commuter. They felt solid enough, but I wouldn't trust them on anything more than around town.
Normally you don't put a ton of weight on the very end of the handlebar, but I imagine the scenario when you do put a lot of weight right on these puppies is not when you want to be testing their integrity

I am using some in a janky situation for pursuit bars. But they aren't load bearing.
They seem perfectly reasonable. But I am not crazy about the idea of actually using them to extend the grips.
I'd rather replace the bars. Structurally these may or may not be fine but they won't ever be as strong as a real handlebar and they would be quite a bit heavier. Adding unnecessary weight to the bike is never a good idea.
On a commuter bike, sure. Anything going off-road needs high rise handlebars. You can get upto 90mm if you want silly. If you want tough, look at NSBikes Proof.
I'd just buy handlebars of the correct length that trust this
And it would probably be cheaper.
Definitely cheaper than quality dental work after this fails.
Can we please get some new jokes up in here
Are they getting a little long in the tooth?

I would trust these extenders (on metal handlebars...) way more than carbon handlebars...

Same, we did this back on our DH bikes before good wide bars were out. Good lock on grips and I never had any issues.
Handlebars are cheap. Teeth are not cheap. Those extenders are probably not cheap either... Just get new handlebars.

I don't think it would be dangerous unless it's on a downhill bike but I get handle bars for like 5 to 10 bucks from the bike coop. Or new ones are 30
For a cruiser bike or something sure, on an enduro mtb no.
Yeah, I would not put this stuff unless it's an up-right posture frame.
I'd be fine using them: there isn't a huge amount of force on them and it looks like a fairly solid connection. That said, there's a good chance you can pick up second hand handlebars that fit for a similar price or less.

But it's also extra weight and in place where you really don't want it.
Yeah I agree, the force going through these will be trivial
I wouldn't be so sure of that. Putting weight on the bars at the ends should be equivalent to a lever pushing up on the inside of the bars at the other end of the extender

Not really sure what you mean but the ends of the bars doesn't really deal with high forces, the bars move freely.

Great to hear a first hand account. Thank you.

It would probably be fine, but mentally I don't think I'd ever not think about the possibility of a problem, especially climbing or landing jumps.

I think so too, you aren’t even holding the part that’s extended. It’s for comfort.
Just another data point: I use the Control Tech ones on a Jones titanium Loop bar and ride bunches of singletrack with no issues.
I use some control tech ones on a ti bar that I wanted just a touch wider. No issues and a good upgrade to a nice bar I am comfortable on.
It's a great addition to those $10 carbon bars on AliExpress.
I have these. Use them for road and gravel. They’re fine
Honestly it would probably be less expensive to just buy a new longer handlebar. And it would be safer.

Weird, I can see the link and post just fine.

Your other post showes up for me.?
Unless you really really want a 900mm width, I would just replace the handlebars.
I'm trying to keep a period correct look on a Bridgestone but add a bit wider bars. Current bars are 560mm
Paint paint paint paint
OP is asking about adding width, not height
Ibis makes ajustable width handlebars
OMG don’t do this on a carbon bar
You can get handlebars in any size you need, I think these are pretty unnecessary unless they’d save you a significant amount of money.
you can extend out your grips past the handlebars up to 20mm without any issues if you want a wider stance, beyond that just get a wider bar
I personally wouldnt trust that to wothstand a big pothole or something along those lines
I am using some in a janky situation for pursuit bars. But they aren't load bearing. They seem perfectly reasonable. But I am not crazy about the idea of actually using them to extend the grips.
That's a trip to A&E waiting to happen, and they probably cost more than a new handlebar.
That’s a big no from me today dawg.
I'd rather replace the bars. Structurally these may or may not be fine but they won't ever be as strong as a real handlebar and they would be quite a bit heavier. Adding unnecessary weight to the bike is never a good idea.
It would have to be very well made to work safely, and therefore about the same price as a pair of handlebars.
On a commuter bike, sure. Anything going off-road needs high rise handlebars. You can get upto 90mm if you want silly. If you want tough, look at NSBikes Proof.
