Need a dedicated helmet for my Gloworm X2

1680 Views 17 Replies 8 Participants Last post by  Hawaii Dave
Hi everyone,

The added weight on my helmet causes an unsafe fit. If I jerk my head back, not too hard but like whiplash, the helmet slides back and exposes my forehead. I think everything is adjusted properly. The same thing happened with my older Bell. The Sena in the photo below arrived yesterday but didn't solve the issue.

I need a new helmet style for my light system. Have you guys found anything that works really well with the added weight?

The light is the Gloworm X2 Adventurer. I think 280 grams.

Thanks,
Dave

Maybe get the battery off the helmet and into a backpack. More awkward to be sure and not as well balanced, but a lot less weight on the helmet.

There are pros and cons to each approach but I do not like keeping the battery separate. That can be a supreme PITA. On a Bell Super 2, strapping the battery to the back of the helmet works really well for me. Zero issues, and I am a picky prick when it comes to things like this.

That said - agreed. Short of buying a new helmet, keeping the battery separate is a fantastic idea (my daughter keeps hers separate using the same helmet as me).

First from your description I question whether your current helmet fits you properly. Without a snug fitting helmet it will be almost impossible to keep it from rocking around making you uncomfortable after a very short time. Next it looks like your using Gloworm's universal Gopro mount which positions the light much higher than their side attached mount (see link). The side attaching mount uses the hole you see in the side of the lighthead as its attaching point (pivoting from there for vertical aiming) and from what I see will cut the mounting height to less than half of what your picture shows which will make the light seem MUCH lighter + less likely to catch on anything. That should negate the necessity of having to reposition the battery from the helmet to your backpack but only if your helmet also fits correctly.

Interesting. Thanks for the input guys.

I did wonder if my helmet fit correctly. The adjustable strap around the head is tight and secure. The chin strap is tight, somewhat uncomfortable. The adjustable piece the cradles the base of the skull feels like it's in a good spot.

Can you do me a favor and test your good fitting helmet. If you grab the front of the helmet and go to take it off like a ball cap, does your helmet stay stuck to your head or does it rotate back? If it does stay stuck what is holding it in place? Is it the chin strap or something else holding it on? I don't think the adjustable headband can hold a helmet on alone with that motion.

Thanks,
Dave
Yeah, if you can't adjust the height of the retention system to hold your head more secure than that, then you need a better fitting helmet. My helmet has barely any movement, but I also wouldn't put the battery on my helmet either.
I can't imagine riding with a heavy battery strapped to the helmet. Its so easy to stash it inside a hydration pack and forget about it.
it sounds like your main problem is that your helmet does not fit right. either it's not a good shape for the shape of your skull, or it's a size too big.

otherwise, don't but the battery on your helmet. attach it by a cord and put it in your pocket or wherever you can carry it.
Never seen the battery attached to the helmet... I agree with previous poster's... run the cable to the backpack. Or spend your money on a new one piece unit/light like the NiteRider Lumina Dual 1800. Unless you just want a new helmet.

it's very common. I used to do that with my Niterider Minewt until I got sick of the weight. I regularly participate in a weekly night ride with over 50 riders and about half of them do this.

2 cell with separate lighthead is my favorite helmet setup. Combo a 5000mAh 2 cell with a efficient long throw 1200 lm light like the Gloworm Alpha will give you more than 3 hrs of high mode runtime and even using higher output lights (Gloworm XS, Magicshine Monteer 3500) you end up getting 1.5 - 2hes. I also don't mind running a cable to my pack when I need a larger battery for longer rides but it's nicer not having to unplug your light every time you remove your helmet. Mounting as shown in the pictures spreads the weight out and keeps it low so actually much more comfortable for me than something like a full sized single emitter Lumina.

Hey, thanks guys.

I'm still trying to figure out what a proper fitting helmet does to keep it secure with the backward movement.
If you pull a helmet up from the top the chin strap will keep it secure.
But, what part of the helmet keeps it in place when you rotate it up and back?
  • chin strap
  • tight fitting adjustable head strap
  • plastic brace the cradles the base of your skull
I would go to the bike shop and try on a bunch but the helmet shelf is bare.

Thank you very much,
Dave

the chin strap is there to keep your helmet from flying off. the chin strap should NOT be the part of the helmet that keeps it in one place on your head. the helmet should have some sort of basket mechanism that make the helmet stay put. you should be able to put the helmet on, cinch down the retention mechanism that sizes it down, and tip your head forward past horizontal without the helmet falling off. if you have to cinch the chinstrap down tight to keep the helmet from shifting around and falling off, it's either poorly adjusted or it's too big for you. the fact that a little extra, balanced weight from a light makes your helmet shift around is further evidence that the helmet is too big or your not adjusting it.

Thanks. You are going to have to trust me that my helmet is not too big. I do have some experience with helmets going back to the leather hairnet that I raced with back in the 1980's. I have 3 helmets and none of them will stay in place with the backward rotational movement. I never became aware of this until I put the added weight on the helmet.

At any rate, did you put on your helmet and try rotating it back? I'm starting to conclude that this is a very difficult motion for a bike helmet to resist.

I understand that I'm coming across as a bone head. I ask for you to please give me a little grace. I'm really trying to understand the issue and go back to my question...

What part of the helmet keeps it in place when you rotate it up and back?
  • chin strap (mine don't unless they are not adjusted properly)
  • tight fitting adjustable head strap (I don't think this alone will hold a helmet in place due to the shape of a head)
  • plastic brace the cradles the base of your skull (possibly?)
Thanks again,
Dave

I just tried your test with my helmet. Tightened it down, no rotating backwards. I don't even need to buckle the chinstrap. The brace that cradles the base of your skull is what keeps it from rotating back. On my helmet, that part can be adjusted up or down to get the fit right. My helmet fits my head like a glove, but not all helmets do.

I still wouldn't put the battery on my helmet...
Sweet, great info. Thanks. The problem is my helmets don't lock in at the base of the skull. It clicks out of place with the pressure and the hold is broken. I need a better helmet. My other helmets are old.
The battery weight is a negative. But the power of 2000 lumens is fantastic.
I got a Specialized Tactic 4 today and it solved my issues. Nice, secure hemet. No problem with the weight. I think the way the MIPS system slides around is helpful with the added weight.
Here's a photo from this evening's ride.
Thanks for the help.
