Have you tried contacting Biknd and see if they can send you a new bladder? Same thing happened to mine and they sent me a new pair. Good luck!

Would be happy to contact them, but have not been able to do so. Contact Us on site does not seem to work. If all else fails, I might write to them by snail mail or call them in Canada.

A free replacement would be nice. I know I can buy a new bladder, but they are not cheap.

Thanks for the suggestion.

Do you have the original or V2 model? I found a puncture in my original but in the V2 I found the internal seams where the bag is bonded to form the ribs had seemed to be pulling apart probably from over inflating and that being exacerbated when you put in an aircraft hold and the outside air pressure makes it worse. I just got a tube of silicone and put a thin smear over all the leaks and areas and fixed it up. The original I just put a bike tube patch on.

I know it is the original Helium, but I'm not sure if it is V1, V2, or V3, but it is not the V4, which is a re-design.

I haven't even looked for the puncture.

Thanks for letting me know an ordinary tube patch worked. May try that if I don't hear of anything more Helium-specific.

Sorry I meant the V4 not V2.The V4 bladder is made of a different material and silicone works well on but a patch was fine on the original.

Found a few small holes in mine, and used a tube patch kit sticker to cover the punctures. Basically, the small circular clear adhesive patch sticker.

Further confirmation that a simple tube patch will work.

Thanks

I have 8 brand new Biknd bladders. I don't use them as I have found a much more effective way of packing my wheels without them.

Unfortunately Biknd has gone out of business so, if you need replacement bladders let me know

If those bladders are for the V4 helium I will purchase them. I need 2 rights and 2 lefts.

I have had 4 different Biknd bags over tge years and they have all used the same bladders.

These one are from the Biknd Oxygen wheel bags.

I would be interested in a pair.
Do you still have some?

I replied to your question but I can't find the post.

Yes I have 4 pairs.

Hi, I will happily take your spare bladders, I live in Madrid, I will happily buy then and pay postage. Thank you

Indeed - that may be the case. Although organizations as large as Outside/Velo don't seem to know this publishing this glowing review of the Helium Case just last Fall - https://velo.outsideonline.com/road/road-gear/biknd-helium-bike-case-review/

I've personally owned and used a Helium Case for 5+ years. I've had a few over the years, but I must say the Helium is the best of ALL of them. It's take the best attributes of a hard and soft case and combined them into one product and added the extra protection element of air filled protection bladders. You can carry 2 pairs of wheels with limited extra bulk. Bikes pack up reasonably quickly, and they roll and move effortlessly.

I have got the art/science of traveling with this down pat - I have gone away for up to 3 - 4 weeks on riding trips traveling with the bike, with a Carry-On and the Helium Case! Because of it's semi-rigid build, the Helium is not the lightest case out there, but you can still pack a good amount of extra gear in it and keep it under the magic 50 lbs number!


Unfortunate they are out of business. When this Helium case wears out. Not sure what I will do?
