Just picked up a used xs Pivot for my daughter.
Needs a new cockpit to get it sized down.

Does anybody make a superlight handlebar for kids? I've got a Wren stem and Trailcraft cranks so its already established that this bike has a rider weight limit. If somebody made a 640mm wide bar with a 100# rider limit that would be perfect.

I went with a set of cheap ($20) carbon bars from EBay. They were just over 100g, they appear to be more than enough for a kid, I would even consider a set for my bike as well.

We did a Chinese carbon one as well, was stupidly light. Paired it with the thin ESI racer's edge grips and it works great for small hands. The chunky's are a hair cheaper and only 2mm thicker as well.

Protaper Junit bars are nice for small hands and can be cut down that small.
I second these as a potential option. The combo of bar and grips is around 230g I think which is usually on par with a light carbon bar and adult grips. I think itll be a bit more compliant being alum and small diameter stuff. We've been happy with them on our 24" with wren stem etc.

Just need to double check, are you sure about that weight?

I just (today!) received the Junit handlebar/grip kombo and they show 327g on the kitchen scale (uncut bar at 680mm). The bar is 260g and grips 67g. I'll cut the bar to 600mm which should shave a few grams.

Before we used the KCNC SC Bone flat bar (aluminium, 600mm) at 131g with the Spawn/Brood grips at 98g.

So the very nice grip diameter reduction (from 28mm to 22mm) comes with about 100g weight penalty for us ?

Ah I'm sure you are right and that I'm transposing some numbers.

About the same as I'd observed in my prior write-up about them: https://forums.mtbr.com/families-riding-kids/protaper-junit-bars-grips-1104307.html

I measured 71g grips and 260g for uncut bars (240g after cutting down to 580mm)

The only published spec on their site says "245g" -- not sure what they were measuring to get to that number:

Am I the only one concerned about strength of a chinese carbon bar? I'd hate for a kid to get sliced open on a broken bar from a crash. I initially considered swapping to a carbon bar and seatpost on my kids' bikes for easy weight reduction but just couldn't do it.

You definitely aren't the only one concerned. But IME for a kid, at least the one we got, there's no way they're going to break it under anything close to normal riding. I've tried breaking one, it would take either a defective one or an absolutely spectacular crash.

I wasn’t too worried, if you get one, you will be amazed at the quality. I have put a lot of force on this one and it doesn’t budge.

I am sure there are some out there that are questionable, but this particular one was impressive.

Yes, I would be concerned if a normal weight person was riding it on aggressive trails. I've seen name brand carbon bars break from unimpressive crashes.
However, for a 75# rider who isnt jumping yet, I think thats a safe application
