Helmet strap question!

I am currently wearing a Giro helmet. But one annoying feature is the adjustment buckle keeps slipping down and the under chin gets loose and floppy. There is a small rubber O ring that , I guess, is supposed to act as a locking mechanism. But it doesn't seem to be working.
Anyone have this bit of annoyance? How did you fix it?
Thanks!

The o-ring is just to keep the strap from flapping around. It doesnít really serve any other purpose. The buckle is supposed to hold the straps in place by friction. I have noticed that some buckles arenít made correctly to have the proper friction and/or some straps are slicker than they should be.

Thereís not much you can do to fix either, however. You might try roughing up the strap material a little to increase the friction. For me, itís usually a self-correcting problem when the strap gets soaked in sweat. Then the strap canít be adjusted because itís stuck together.

I have a Giro helmet too. I don't mind this aspect to their strap(s). I just snug it up when necessary. this time of year, I'm adjusting the back knob & strap due to changing headwear underneath. been trying out a Basecamp helmet lately which has a red cloth velcro wrap-around under the chin, maybe it serves a similar function to the Giro o-ring? if you're not using that o-ring to contain the loose end maybe if you did the added friction (of all straps against ea. other) would keep it from moving as much? maybe you can get an add-on chin cushion that wraps the strap & maybe it will help keep it from slipping. & maybe a short narrow piece of tape of your choice (color to suit) in place of the o-ring will keep it from slipping. I know electrical tape comes in may colors

I've taken to sewing the buckle in place once I've determined the proper adjustment.

I have found the strap webbing length always miserly, in it being too short.
the one I use is at the very end of adjustable length..
I have several that are to Frickin' short .. by now

don't get old...

Guitarists sometimes use resin to hold a "floating" bridge from sliding on the guitar. Might work for a helmet strap?: https://www.ebay.com/itm/222732829464

Have the same issue on my Lazer helmet. I had thought about sewing in position as @JohnDThompson suggests; however, because I need some adjustability when I wear a cap or beanie under my helmet, I am not sure that it would suit my need. Unless I keep it a bit loose.

Bending the subject a bit: My observations is that 9 of 10 helmet wearers have the straps too loose, which limits its effectiveness. This is even worse amongst children, who typically wear their helmets on the back of their head.

My Giro helmet is the same...I have to re-tighten it every month or so. Interesting idea about sewing it...the straps as they are stink.

In my experience it happens with pretty much every make of helmet. I'm currently using a Giro helmet which seems better than average in that respect.

You should be able to put two fingers under the strap under the chin. That will make the straps look a bit loose. However, modern helmets depend less on straps than older styles due to the retention devices in most helmets now. The straps are still needed but they just aren't as important as they were on the Bell Biker.

All I've ever owned are Giro helmets. The straps are the worst part of the system.

This isn't quantum physics guys.

If adjusting a helmet strap is too much of a bother then perhaps a different hobby is in order.

Reach up, grab the strap and pull. You can stop pedaling and just coast if you want.

I would try positioning a cam buckle on the loose ends of the strap so it wouldn't pull through the adjustment buckle.

I only use the type of helmet that has the screw adjustment on the back of the head and let the straps dangle loose or as soon as I start huffing and puffing it feels like the strap is strangling me. I only have this problem with bicycle helmets for some reason.

Yes, Lazer straps are terrible.

I previously tried making a secondary band out of a strip of an innertube, so it would hold the ends together right at the buckle. It didn't help.




~~~
Even worse is the slider that controls the merge of the two straps. It slowly slides down over a few rides until it's all the way down near the buckle. Grrr. This design only uses a friction fit, unlike my older Bell that clamped the slider in place.

So I tried a couple of dabs of Gorilla Glue on the back side. This slider never needs to move once it's set. Gorilla Glue worked great on my saddle bag clip that kept moving.
But it didn't hold here, the slider has slid. I might try sewing it in place.

Front:


The back side, with the glue spots.



My new fix
After reading this thread, I added a slice of an 18-23mm innertube. It's a good fit over the buckle, and keeps the straps tight against the buckle. I'll see if it actually retains the buckle in place. Should at least slow it's movement.

I sent a note to Giro about the problem. They responded saying they do not have replacement parts but will exchange the helmet. As long as I can get the same model I may go this route.

Only 2 fingers? My observations are in the range of 8 fingers, 2 thumbs, and a couple of Snickers Bars. Loose enough that you don't need to undo the fastener to take it off. Sneeze and the thing will be flung into the air. I see so many riders that way.

Thanks!
Just use a needle and thread, and put a couple of stitches through the strap and tie a knot. It is clean, durable, and does not ship. Use the heaviest thread you can find. nylon thread works best, because you can melt the ends of the tread together. I have used this method on several helmets including the last 4 which were Giro.

We used the same method on our parachute harnesses once they were dialed in.

Thought about the sewing idea but as I wear different hat thickness es as the weather changes it would loose the ajustabilty. Thinking of filing a "tooth" in the buckle to give it more bit.

I use hockey tape. Just cut to 1/2" wide and wrap it a few times around. It never slips.

I use the same tape to wrap my CO2 cartridges.
